Sony A7r: dream camera with crippling autofocus shortfall?

Friends and I have been playing around with the Sony a7R, supposedly the dream camera of 2013. Indoors, it turns out to be very slow to autofocus, to the point that it is almost unusable for conventional family photography. A friend who is a regular Nikon D800 user said “I really wanted one of these but now that I have seen how slow it is, I will stick with a conventional SLR.” This was after an hour or so of taking pictures at a noon to 2 pm party lit by a fair amount of window light and also some incandescent bulbs (i.e., much darker than outside but nowhere near as dark as a home interior at night).

I tried it last night taking pictures of a sleeping baby in a room lit by a table lamp. A Samsung Note 3 mobile phone didn’t have any trouble capturing focus on the baby’s face (though the result was grainy). The a7R hunted, despite blasting the baby with a bright AF illuminator. It really was not a usable device, though in theory it has reasonable manual focus capabilities (hard for an old Canon EOS user to wade through Sony’s interface, though!).

For now I think it is safe to say that the Sony a7R is a dream camera for landscape photographers looking for a lightweight hiking companion but I don’t think it is as good a general-purpose camera as an Sony NEX-6 (still slower than an SLR but usable).

Is all of the excitement about mirrorless cameras misplaced? The old Canon Rebel G film body was very light and compact and had much better AF than this latest Sony (at 10X the price!). I’m wondering if we aren’t all suffering from a collective delusion and if it wouldn’t be better to stick a sensor in the back of a Rebel G.

I’ve posted some example images on Google+ and will be adding to the collection periodically.

U.S. military saves taxpayer dollars by replacing $300,000 helicopters with $6 million ones

A friend sent me this ArmyTimes article about the U.S. Army “cutting costs” by replacing old Bell JetRanger helicopters (the civilian 206B equivalents are available in airworthy condition for $300,000 to $500,000).

For active duty, the $300,000 single-engine machines will be replaced with $20 million twin-engine Apache helicopters. For primary training, students will learn to hover in $6 million twin-engine Eurocopter EC-145s (the “Lakota”). After you’ve paid the $6 million, what do these cost to run? Back in 2011 Conklin and de Decker estimated nearly $1200 per hour (source), i.e., nearly triple the cost of the EC120, a modern equivalent to the JetRangers that will be retiring.

[What do other countries do for primary training, you might ask? Some have decided to use the Robinson R44, whose brand new purchase cost is about $350,000 and whose direct operating costs are about $200 per hour. Where 100LL gasoline is impractical to obtain and brand new helicopters are desired, the jet-powered Robinson R66 is getting some military sales. These are about $800,000 to purchase with direct operating costs of perhaps $350-400 per hour.]

If this really does save money, I think our flight school needs to look into getting rid of our single-engine Piper Warriors ($30,000 to $80,000 in value, depending on vintage and engine time; about $85 per hour in operating cost). We could replace them with brand-new twin-engine jet-powered airplanes that cost $800 per hour to operate and then reduce our prices for customers.

Obamacare = health care for the poor

I’m the secretary for the MIT Class of 1982. I recently sent out a request for news to be published in our alumni magazine. I asked folks if they had anything interesting/exciting/funny to share that related to Obamacare. I promised anonymity to anyone who was involved with the healthcare.gov debacle. This unleashed a firestorm of rage from Obama supporters and I was accused of “ridiculing efforts to provide health care to the poor.” Nobody questioned the equation of Obamacare with “health care for the poor.”

Given that this is a group with a lot of age, experience, and education, I think it is safe to say that Obamacare has won the PR battle. A fair number of people are attributing to it all of the things that they like about Medicaid (the actual government program to provide health care to the poor, established in 1965). I wrote about this in November 2012 and I’m wondering to what extent it is possible for politicians to take credit for doing things that the government is already doing. Could a politician convince voters, for example, that prior to his election there were no streets? That they needed to vote for him and his party in order that surface transportation remained possible? Probably not, but presumably there are harder-to-observe portions of government where the public might forget that a service predated a politician’s claim to have delivered it.

Anyway, it seems as though Obamacare will be permanent because all that supporters need to do to shut down any criticism is to assert that the critic is trying to strip poor people of health care. Especially at Christmas it would take quite the Scrooge to suggest that less than 100 percent of GDP might be spent on aiding the suffering.

[I should add that the most vociferous supporters of Obamacare among the class members, and the ones most likely to take the position that every American had a moral duty to support both President Obama and Obamacare, were physicians, i.e., folks who will draw approximately 67 percent of their revenue from the government. (source: Forbes). Employees of Lockheed Martin must be jealous. If you say that you’d rather our national wealth be spent on something other than the government giving them $200 million for an extra F-35 fighter plane, Lockheed Martin workers who would collect some of this as salary can’t call you immoral.]

Do variable annuities make sense for retirement saving?

Folks:

When I was in my 20s the end of a calendar year was a time to eat 12 plates of food at family dinners. Now it is an occasion for tax and retirement planning. So sad…

I’m poking around looking at ideas that might be better than just sticking money in a taxable S&P 500 index fund.

What I would really like is what state government workers get, i.e., a pension that starts sending me monthly checks when I turn 65 years old and adjusts those checks to account for inflation. So far I haven’t found a product like that. Does it truly not exist? If so, it is interesting that Detroit thought that they could provide this to their workers without going bankrupt. If Goldman Sachs and the rest of the Wall Street geniuses can’t figure out how such a product should be priced, why did states and cities think that they could do what the world’s most sophisticated financial services industry could not?

Insurance companies offer annuities, but they start paying immediately and don’t adjust for inflation. I’m 50 now. By the time I am 65 what seemed like a fat annuity check today might be the price of a Diet Coke. (Note to folks who ask why insurance companies can do this without going bankrupt as Detroit did… life insurance companies save money on their insurance polices when human lifespan is extended so they can use those savings to keep paying annuities that they have promised. When General Motors went bankrupt their oldest pensioned worker was 115 years old and GM had no way to benefit financially from people living longer.)

The “variable annuity” is something that I can’t figure out at all and I want a reader to explain it to me. The basic idea of a variable annuity is that you put money into it today and the investment returns compound tax-free until you decide to start taking money out for retirement income. Vanguard sells them at what they claim (source) are low fees. It turns out, however, that “low” means at least 0.5 percent per year more than the fee on a corresponding index fund. As the S&P dividend yield right now is 1.9 percent (source), that means that one quarter of the yield is raked off to pay Vanguard and its insurance company partner. This sounds suspiciously like paying taxes on qualified dividends plus the new Obamacare rake. If yields were 10 percent and tax rates on dividends were 40 percent this product would make sense to me. But if all of the benefits of tax deferral accrue to the insurance company and/or Vanguard, why go to the trouble and take the risk that the insurance company (think AIG!) will go bankrupt between now and when you need the retirement income?

Are people still buying variable annuities in this low-yield environment? If so, why?

[Oh yes, if you’re looking for a little humor from the financial services industry, here’s a gem from the Vanguard web site: “Note: The American Taxpayer Relief Act of 2012 (ATRA) raised the top marginal income tax rate to 39.6% and the top capital gains tax rate to 20%.” (emphasis added)]

Business opportunity: software to calculate welfare cliffs?

Today’s New York Times has an article “Health Care Law Frustrates Many in the Middle Class” about Obamacare. Amusingly this is summarized on the front page with “While the Affordable Care Act clearly benefits those at the low and high ends of the income scale, many middle-class Americans don’t qualify for subsidies, and are facing steep premium prices.” How is that that people at the “high ends of the income scale”, who don’t get any subsidies and must pay a new 4% income tax surcharge, receive “clear benefits”? The authors of the article explain that rich people are different from the rest of us and don’t mind paying more for the same stuff (“rich people can continue to afford even the most generous plans”).

More substantively, the article talks about a family in New Hampshire that makes $100,000 per year but if they were able to ask their employer for a cut in hours so that they made $94,000 per year they would receive $6000 in subsidies from federal taxpayers. Given that the $6000 pay cut would be pre-tax and much of their health care spending is after tax, these folks would be financially better off working fewer hours and receiving lower wages. Not to mention the fact that the family would be emotionally better off if the wage earners had more leisure time.

The phenomenon of welfare cliffs is well-known for lower income people. This chart shows that a $29,000 job can yield a better lifestyle than a $69,000 job, for example. This is even more dramatic in cities with high rents, such as Cambridge, Massachusetts, where preserving one’s low income status can result in $50,000 per year or more in housing subsidies alone (equivalent to pre-tax earnings of $90,000 per year?).

With Obamacare, though, folks who earn more than average may nonetheless face a welfare cliff. Does this present a business opportunity? What about a web or phone app that takes into account the various subsidies available from local, state, and federal governments and advises the user on the after-tax and after-welfare effects of pay increases and decreases from their current salary? This is now a lot more complex than it was before Obamacare and it isn’t a simple matter of going to ADP.com to use a pre-tax/after-tax calculator.

[The other amusing thing about the article is that they cite “Experts consider health insurance unaffordable once it exceeds 10 percent of annual income. ” But they don’t explain how it is that adding layers of complexity and bureaucracy can somehow make it affordable for a nation to shovel 18 percent of its GDP into the maw of the health care industry! (and it will be “close to 25 percent of GDP in 20 years” according to this fall 2013 Brookings Institute paper)]

Why doesn’t economic inequality bother us within a field?

Income inequality has been in the news lately, notably with Barack Obama’s pitch to raise the minimum wage. The statistics are kind of ugly. Some people get paid a fortune while most of us do not.

People can differ when comparing wages across fields. In October I was at Korean BBQ restaurant in Manhattan sitting across from Venus Williams. One of my companions said later “I don’t see why she gets paid so much to hit a tennis ball. My friend is a cancer researcher doing much more worthwhile work and he doesn’t get paid a lot.” My response was that people dropped dead every day from cancer and therefore his friend wasn’t doing an obviously great job. Venus Williams, by contrast, inspired tens of millions of people all over the planet as to what were the limits of human capabilities.

What about within a field, though? I have taken over all of the shopping and cooking in our apartment since our baby was born (1.5 weeks ago). In addition to making the inconvenience of pregnancy and the pain of childbirth seem insignificant, the results of my kitchen experiments I am sure are convincing the rest of the household that the chef of a Michelin-starred restaurant should be earning at least 100X what I might earn in the same field.

Consider also writing. In theory this is something that nearly 100 percent of Americans learn how to do. Yet some people cannot put together a single grammatical sentence while others can write a complete bestselling novel. It doesn’t seem unreasonable that the minimum wage is too high for a writer whose work is disorganized and needs thousands of dollars worth of copy-editing and at the same time that Stephen King might earn $20 million per year (source: Forbes).

In fact, considered in this light we would expect tremendous income inequality in any field except those where productivity is fixed (assembly line) or irrelevant (government).

So why are we continually surprised and, in some cases offended, that people earn different amounts? Is it because of people who get ahead seemingly unjustly, e.g., Bob Nardelli collecting hundreds of millions from Home Depot shareholders while earning a place in the “Worst American CEOs of All Time”? Aside from my friend, who is more passionate about cancer researcher compensation, most Americans seem to think that it is fair for sports stars to earn a lot. Is that because, absent doping, it is obvious that the sports star reached the top through fair competition?

[Separately, it might be worth looking at what politicians are proposing. As a remedy for income inequality, Obama suggests in his December 4, 2013 speech “strong application of anti-discrimination laws” and cites the figures that “women still make 77 cents on the dollar compared to men.” Given that government and government contracting is now nearly 50 percent of the economy, how can this be the result of sex discrimination unless the government itself is discriminating? Does it make sense for the CEO of the largest employer in the United States to say “Employers nationwide have to stop discriminating”? Why hasn’t the government snapped up all of these highly qualified underpaid women (this would roughly double their compensation (see this study))?

Obama’s next solution is “immigration reform” but immigration is a huge contributor to income inequality since a person who is new to the U.S. and may not speak English is going to earn less than a native-born citizen.

Obama then decries “disparities in education” but generally politicians like Obama fight against school vouchers that would allow poorer Americans to send their children to the private schools that are favored by wealthier Americans. Obama says that “obesity” among the poor contributes to income inequality but the New York Times reports that the USDA encourages industrial food companies to cram more cheese into everything. Why wouldn’t Obama use his executive authority to shut this down instead of decrying obesity? Obama attacks “absent fathers” without mentioning that a lot of state governments encourage this by making divorce and child support lawsuits highly lucrative for mothers (see “Child Support Guidelines: The Good, the Bad, and the Ugly” by Brinig and Allen for how some states encourage divorce). Obama complains about “isolation from community groups” without mentioning that higher tax rates and a bigger government will necessarily crowd out community groups. When the government is providing housing, food, health care, etc. to the poor there is less of a role for a community group to play. (This may be why Bill Gates and Warren Buffett, for example, concentrate their charitable efforts outside the U.S.)

Obama argues that a higher minimum wage will not eliminate jobs or raise costs to consumers. It will be truly a free lunch. But maybe there is a third possible consequence: it will eliminate poorly skilled Americans from the work force in favor of additional immigrants. As I noted an August 2010 posting, the cost of a poorly skilled person in a factory or office is now much higher than it was. Add that to a high minimum wage and an employer will simply fire poorly skilled Americans and learn more heavily on the H-1B program. So there can be the same number of jobs and roughly the same costs to consumers, as President Obama says, but more Americans on Welfare and more immigrants working.

Obama says “I challenged CEOs from some of America’s best companies to give these [long-term unemployed] Americans a fair shot.” Yet, as noted above, Obama himself is the CEO of America’s largest employer. Why doesn’t he hire these folks? The government spends huge quantities of taxpayer dollars recruiting young people fresh out of college. Why not shut that down and hire folks who just graduated from 99 weeks of Xbox? The government provides excellent jobs in air traffic control (more than $200,000 per year in total comp) and trains people for those jobs. Currently the government discriminates against anyone over age 30 by flatly refusing to hire them (FAA policy). Obama could adjust this regulation to allow 35-year-olds who’ve been unemployed for at least two years to apply.]

A relaxing lunch with an emergency physician

I had lunch today with a friend who is an emergency physician. She congratulated me on the recent arrival of our son and said “Oh, don’t let anyone touch him for the first couple of months.”

Why not?

“If he gets a fever he needs to go to the ED and will get

  • stuck with a needle for blood and blood cultures
  • catheter urine specimen or needle into bladder (via suprapubic route)
  • lumbar puncture (what the lay public thinks of as a spinal tap) to rule out meningitis (newborns don’t have a well-developed blood-brain barrier yet)
  • IV antibiotics
  • +/- chest xray
  • hospitalization until results back (culture results take a couple days or so)”

Armed with a little knowledge, I feel much more relaxed now…

Christmas Gift Ideas for Photographers

If you’re shopping for a photographer this Christmas, here are my best gift ideas (sorted in order of increasing price):

Michael Freeman’s Photo School Fundamentals: Exposure, Light & Lighting, Composition. Michael Freeman has been writing my favorite photo tutorial books for decades. Even experts will find some inspiration here and the book is also good for experts because experts are often called upon to teach beginners.

CowboyStudio light tent. Camera phones have pretty reasonable macro capabilities. If placed outdoors on a sunny day, this will enable some interesting photos of smaller items. Usually it is better to improve the lighting and background than to get a fancier camera.

Westcott folding reflector is a great way to work with natural light but remove shadows from eye sockets and/or add some warmth to the image.

tripod plates and/or ballheads for existing cameras from Really Right Stuff

Genesis by Sebastiao Salgado, arguably the photo book of the year.

On This Earth, A Shadow Falls or Across the Ravaged Land by Nick Brandt. Amazing books because he used film(!) and short lenses to photograph elephants. It is a totally different perspective than the usual long-lens wildlife photo.

a softbox lighting kit is the foundation of most portrait studios

gift certificate for aerial photography at your local flight school (helicopters are ideal)

A Sony NEX camera is perfect for parents because nearly all of the models have rear LCDs that flip up, enabling eye-level photographs of younger children without the grown-up having to bend down. The kit 16-50mm lens is remarkably compact (it retracts when you shut the camera off) and high quality considering the price. The NEX-6 has an eye-level viewfinder that is useful in very bright conditions. The NEX-3 and NEX-5 offer excellent image quality and are as cheap as $370 including lens. Add a Think Tank Mirrorless Mover camera bag if you’re planning to get additional lenses.

Apple iPhone 5s. The practical capability of the iPhone camera is vastly better than similarly spec’d Android devices. The 5s in particular has some interesting innovations that improve image quality.

Carl Zeiss Optical 8×42 Victory HT Binocular. Photographers love good optics. If your loved one does not have binoculars, these are at the top of almost every comparative review.

Sony a7R (check this review on The Verge). This camera has the image quality of the Nikon D800E, the world’s highest quality conventional camera, but in a point-and-shoot-style “mirrorless” format. The body doesn’t do anything without a lens, so add the Sony/Zeiss 35/2.8 lens. Don’t get this camera if the recipient’s main interests are photographing sports, wildlife, or portraits. For those, he or she will still need a traditional Nikon, Canon, or similar SLR system.

Zeiss Otus 55/1.4 lens for Nikon (also available for Canon). Check the DxoMark review. This may be the best consumer lens ever made and is perhaps the only lens that can bring out the full potential of the Nikon D800/D800E.

Canon 200-400/4L 1.4x soccer mom lens. This is a revolutionary zoom lens for Canon EOS system users. Good for sports and wildlife. Don’t forget the Lowepro Lens Trekker 600 AW II Backpack for when the recipient needs to walk more than 10 feet from the car.

Hasselblad H5D-60 medium format digital camera. Good for studio photography of people and clothing. Budget another $20,000 for a few lenses…

[Comments from readers with better gift ideas would be welcome. Also I wish someone who uses a medium format system would tell me why it is better than a D800!]

End of year charity idea: Kids on Computers

If you’re doing end-of-year accounting and tax planning and trying to find a way around the new Obamacare taxes, perhaps a charitable donation is in order (though when you add the Obamacare taxes to the Alternative Minimum Tax, it is probably unclear to anyone other than KPMG partners what the actual savings from charitable donations might be). One of my personal rules about charity is that I avoid donating to organizations whose employees earn more than I do. I check the Form 990 using Guidestar.org to learn about the compensation of the best paid employees. (Side note: I designed the Oracle data model for an early version of the site and then loaded a huge data set from the IRS into Oracle. To see whether hundreds of thousands of organizations had loaded properly I did a few queries. Harvard quickly popped out as the richest non-profit organization in the U.S.! Side note 2: This doesn’t mean that I think the work of a non-profit where the CEO earns $1 million is unworthy, only that I think the donations for that non-profit would more logically come from hedge fund managers, investment bankers, et al.)

One 501c3 group that readily meets the above standard is Kids on Computers. It is an all-volunteer organization currently led by Avni Khatri (avni@kidsoncomputers.org). Because nobody draws a salary, 100 percent of donations go to fund operations. (I wrote about them back in July 2013 seeking laptops.) What kind of folks in this day and age actually need any introduction to the digital world? Avni just came back from setting up a lab in India and the school was a two-hour drive from the nearest hotel with flush toilets.

Here are the bragging rights possible:

  • $25,000 will fund a local employee to work for three years on a part-time basis visiting and maintaining labs in one of the countries served (Mexico, Nepal, Argentina, India; your choice). You’ll get credit with a blog posting.
  • $10,000 will fund a new computer lab, to be named after the person of your choice. You’ll get credit with a blog posting and permanent credit on http://www.kidsoncomputers.org/labs
  • $1,500 will fund a volunteer’s travel expenses to go to Mexico for two weeks to maintain the computers in up to eight labs and provide continuing education for the teachers and the students associated with those labs. You’ll get credit with a blog posting.
  • $250 will buy one computer (you get a photo emailed to you of a student using your computer; label attached to computer with “Donated by YOUR NAME” or “Donated in honor of YOUR CHOICE”)
  • $120 will buy shipping for four laptops to an international location. Laptops are shipped in USPS Medium Flat Rate boxes, each of which holds two laptops.
  • $35 provides one child access to a computer, educational software, and internet (where accessible).

[For the last two, add your own bragging rights by commenting on this posting saying why you wanted to help these kids.]

You can donate via PayPal (link). Please contact donations@kidsoncomputers.org if you’d like to mail a check.

You can skip out on Obama’s new tax on capital gains by giving appreciated stock or mutual fund shares directly to the 501c3. The Vanguard form is a good example of how to do it.

Avni is also looking for computer-skilled volunteers who speak Spanish fluently to travel to Mexico for a two-week period and help with the labs. Mostly the kids are learning the basics of using a file system, editing and saving documents using Open Office, watching Khan Academy videos and using offline Wikipedia. So you don’t have to be a wizard programmer to contribute.

If you’re interested in volunteering for the Mexico trip, please send me an email with your qualifications. I will pony up the $1500 to send you to Mexico if you will agree to write a guest entry on my Weblog, complete with photos and a video (to be edited and uploaded by you to Youtube!).

An insured day in the American health care system

Being the parent of a newborn means never straying too far from the medical system. Today was our son’s first pediatric appointment outside the hospital. Alexander Daniel is on a gold-plated Blue Cross policy so cost is not a concern and we have our choice of physicians to see.

After a short wait and some paperwork, we bounce between the doctor’s office for discussion and an adjacent exam room. Every time we go back and forth or need to adjust an item of the baby’s clothing, the doctor runs out to see a patient whose visit is running in parallel. I’m not sure if this is standard procedure, but given the paltry amounts that insurers pay for office visits (see this 2010 posting about my doctor billing $510 and collecting $83), I can’t think of any alternative for the doctor.

The pedi does apologize that things are a little slow/chaotic on this particular today. How come? “We’re just installing a new electronic medical record system. And to make it work we had to get new computers because the system didn’t support Windows XP.” Was he going to run Practice Fusion, the free Web-based system? “No. We have to run eClinicalWorks. It is required by Mt. Auburn Hospital, with which we are affiliated.” Was he then upgrading to Windows 8? I could see how that would throw the office into disarray for a few months (or years). “No. eClinicalWorks doesn’t support Windows 8 so we installed Windows 7. But on the other hand they are talking about switching everyone over to Epic so we might start over in a year.”

The doctor suggested that we get flu and Tdap vaccines, but since we are not technically his patients he cannot give it to us. So we’ll need another encounter with the health care system to get these.

Then I went to the neighborhood (old-school family-run) pharmacy to get a prescription filled. They had to do some compounding. “We can’t bill your insurance company,” the pharmacist noted, “because even though we start with an FDA-approved drug, if we’ve compounded it then it is no longer FDA-approved. You can submit the receipt to them and try to get them to pay it. Usually the deductible is so high that it isn’t worth it.” I handed over $45 and didn’t ask for a receipt.

I’m wondering why Americans are so confident that they need health insurance and that, indeed, health insurance is such a good idea that people who don’t want it should be forced to buy it. Food is more important than medical care since without food a person will surely die. Yet we don’t force people to carry “food insurance” and then have the food insurance company authorize particular food providers to serve meals at times and places of the provider’s choice. If people are poor we give them a debit card (SNAP or “food stamps”) that they can use at the supermarket of their choice, with roughly the same shopping experience as a customer using cash. Poor people are lifted up to enjoy a middle-class shopping experience. In health care, it is the opposite. Middle class people are dragged down to endure the same customer service experience as a poor person dependent on Medicaid. If we hadn’t been forced by convention and now law to hand over $20,000 per year to insurers for our family’s medical care we would have been delighted to pay $160 for an appointment with a doctor who could spend a calm 30 minutes with us, rather than $83 for a rushed 15-minute appointment. And the $45 bill for the prescription wouldn’t have bothered me at all if I hadn’t already paid for prescription drug insurance that, I thought, paid for prescriptions.

The pharmacist put it in terms of dollars and cents: “People think that they can save money by buying insurance. They never wonder how it is that all of the people who own insurance companies got to be billionaires.”
