Leica digital cameras tested by DxO

DxO has published a test of three very costly Leica digital rangefinder cameras, heirs to the legendary M-series of film cameras.  The results of the objective test are not pretty: “these cameras offer the worst image quality DxOMark have tested on a full frame sensor, with the exception of the 10-year-old Canon EOS 1Ds.”

The CCD sensors in these Leicas turn in numbers that are more like those of a point-and-shoot Sony RX100 and far behind the disposably-priced-by-comparison Sony NEX cameras.

Either the objective tests are missing a lot of what is important to the human eye or humans who praise the results from these Leicas in non-blind tests are highly suggestible.

How do stockholders today compare in wealth to those in 2007?

The stock market is up in nominal dollars (“mini dollars”). How are U.S. investors doing compared to 2007? The S&P 500 peaked at 1565 in October 2007. According to the Bureau of Labor Statistics, it would need to be 1738 today, about 12 percent higher, to yield the same spending power.

If we measure spending power in bars of gold, the S&P 500 has a lot farther to go to recover the losses since 2007. Gold was $800 per ounce in October 2007, so the S&P 500 was worth 1.9 ounces. With gold at $1600 per ounce today you’d need the S&P 500 to be over 3000 to have the same buying power.

If wealth is to be measured in spending power another consideration is tax rates. The only way for an investor to get a return is via capital gains or dividends. Taxes on that kind of income have gone up by roughly 11 percent of the total received since 2007 (federal income tax adds 5 percent; state income tax perhaps another 2 percent; ObamaCare surtax tacks on another 4 percent for people in households making $250k/year or more). Consumption taxes, e.g., sales tax and hotel and restaurant taxes, have gone up 2-3 percent. So it seems reasonable to conclude that the S&P 500 would have to go at least 15 percent higher in order to compensate for these new taxes.

My back-of-the-envelope calculation is therefore that the S&P 500 would have to rise at least another 33 percent, i.e., to about 2000, in order to yield the same spending power that it had in October 2007.

Catching up with old friends this week

Nearly thirty years ago I worked at an MIT spinoff company populated by troll-like computer programmers. In the midst of these frogs was a beautiful blond princess, the treasured daughter of a WASP family in Maine. Despite the multi-decade interval, she recognized me at the Whole Foods in Weston yesterday in the mid-afternoon [note: Weston is one of Boston’s wealthiest suburbs]. Despite being in her early 50s she was little changed: slender, beautifully dressed, perfectly coiffed. Her phone was full of photos of three healthy attractive children. I felt very happy for her as I watched her get into her Mercedes SUV. She had dodged so many bullets to get to this point in her life without anything truly bad occurring.

Today was unfortunately not as joyful. It started well when I gave an Antarctica slide show at my daughter’s day care center. One big difference between teaching 4-year-olds and MIT undergrads is that the MITers very seldom hug the lecturer at the end. The questions got fairly technical, though. One child asked how it was that whales were able to rise to the surface after diving deeply. This led to a discussion about buoyancy due to air inside the whale and the fact that the air expanded a bit every time the whale rose to a higher point in the ocean. Another child asked how were whales able to move forward when swimming, which prompted a discussion about Newton’s Third Law.

After lunch, however, I went to visit a 61-year-old friend who has been suffering with liver cancer (I lost a dog to this disease in 1991). He had been enjoying working and had planned to work until nearly the end, but a decision to try chemotherapy forced him to stop: “The side effects from chemo just destroyed my ability to do anything. But I didn’t want to just do nothing. Anyway, the chemo had no positive effects, which was the most likely outcome.” He was trying to stay home as much as possible: “Being in the hospital is horrible. They woke me up at 4:00 am once to ask whether I was sleeping well.”

Diversity training and outsourcing

A friend of mine is a top science researcher working as a professor at a state university. Every year he is required to take several hours of diversity training and sexual harassment training. With a lab full of grad students and post-docs, an experiment on another continent, a full schedule of talks, and young children at home, how does he find time for this? “You can’t just turn the videos on and try to work. The software monitors your mouse movements. So I hire this company in India that Tim Ferris, the four-hour workweek guy, promotes. They take the training on my behalf.”

What do we get 40 percent more of from the federal government compared to 2007?

A friend sent me this editorial cartoon showing the federal budget and proposed $85 billion “sequestration” put into perspective with a pie illustration. I think it a fun data visualization exercise, but when I looked a bit deeper I became skeptical. The cartoon shows federal spending as having grown 40 percent since 2007, from $2.7 trillion to $3.8 trillion. That did not seem credible but it is backed up by

What is it that we’re getting 40 percent more of?

[Related: my own attempt to make federal budget numbers comprehensible by dividing by 10 to the 8th power (April 2011). This analysis caught the public imagination and appeared in a bunch of magazines and Web sites, usually with the original source long forgotten.]

Sony RX1 image quality measured objectively

The cruelly objective folks at DxOMark have tested the Sony RX1, a camera that has inspired Leica-like devotion (e.g., see the reader reviews at Amazon). It turns out not to be that exciting from an objective measurement point of view. The fancy Zeiss lens tests out with similar numbers to a Canon 35/2 lens and it lacks the Canon’s image stabilizer. The Sony’s Zeiss lens does come up with a better overall score but the notes say that is mostly because the Sony sensor is better than the Canon 5D Mark II sensor that was placed behind the Canon lens for the test. How about the sensor? Really great.. just like the same sensor, more or less, that Sony sells Nikon to put into the D600.

So for the price of a Nikon D600 and a good 35mm lens you get the same image quality and seriously compromised picture-taking capabilities compared to a standard DSLR (see the conclusions in the dpreview.com review).

The Sony does seem like kind of a fun toy for people who love the 35mm lens perspective (I’m not one of them) but the test results don’t show it to be magic compared to a modern Nikon body and well-engineered 35mm prime lens (e.g., from Sigma!).

What do we know that Roman physicians did not know about diet?

A friend of mine passionately follows New York Times articles about new medical diet studies, e.g., “eat blueberries and you won’t get Disease X.” My response to her admonishments to read and then adhere to these diet fads was always “You can read all of the best medical literature on diet and by the end of the project you won’t know any more than a good physician in Ancient Rome. The Roman doctor would have said ‘Don’t eat too much meat. Eat a lot of vegetables. Maybe some fish. Get exercise.’ What more or different would a modern doctor say?”

Now it turns out that even the New York Times is confirming what I was telling my friend for the last 10 years with “Mediterranean Diet Is Shown to Ward Off Heart Risks”. After 2000 years of progress the 10 lb. heads behind the study advocate that people eat “olive oil, nuts, beans, fish, fruits and vegetables, and even drink wine with meals.”

So that gets back to my question… what do we know today that the Romans didn’t know about diet and lifestyle? The main thing that I can come up with is the dangers of lead exposure.

[Separately, this video is a very thoughtful analysis of the latest diet bestseller… Wheat Belly.]

Linguistics and government: What does a spending “cut” mean?

Yesterday’s New York Times carries an article entitled “Fear of U.S. Cuts Grows in States Where Aid Flows.” Google Chrome says that the word “cut” occurs 32 times on the page. It sounds like a natural disaster: “The impact would be widespread as the cuts ripple across the nation over the next year”. Yet buried near the bottom is an interesting paragraph: “Even with the automatic cuts, the analysis found, states are still expected to get more federal aid over all this year than they did last year, because of growth in some of the biggest programs that are exempt from the cuts, including Medicaid.”

So.. federal spending is being cut. Which is why more money will be spent this year than last year.

High tax rates discourage women from pursuing promotions?

Sheryl Sandberg is getting people excited about her new book, Lean In. It seems as though this would be a good time to add to the “Aid to Evaluating Your Accomplishments” page (hit reload a few times to see the names change). Most of us would be happy either to (1) care for an infant child, (2) run one of the world’s most valuable companies, or (3) be the author of a bestselling book. Sandberg is doing all three simultaneously.

Sandberg’s life sounds pretty good but not every female executive can rise to such levels; there simply aren’t very many jobs as good as being Facebook COO. The typical female (or male) executive can expect to end up somewhere in the middle of a pyramid.

The men that I know seem to seek promotions uncritically. They don’t need a much larger salary in order to take on a larger responsibility. They’re happy to go from “Director” to “Managing Director” or “VP” to “Senior VP”. As Napoleon said, in reference to medals, “It is with baubles that men are led”.

Some women friends though, tell a different story. One who lives in San Francisco is typical. She earns a very comfortable salary, more than $200,000 per year, managing a small team. She was offered a promotion recently that would have paid her about $9000 per year additional. She cited federal income taxes, California state income taxes (among the highest in the nation at up to 13.3 percent), and an additional San Francisco city payroll tax in calculating that at most she would be able to spend about half of the additional money, netting perhaps $4500 per year. She decided that it wouldn’t be worth it because the bigger job would involve more hours of work and more travel time. Her hourly after-tax wage would actually have fallen. Other women talk about being bored to death watching PowerPoints in endless meetings. The higher up in the pyramid, the more time spent looking at PowerPoints and the less time doing anything productive and therefore satisfying. Asked about the value of titles, a female MBA said “I care about the hours that I have to work and the salary that I get paid. They could call me ‘secretary’ and I would be just as happy.”

It is far from obvious that it is rational to want to climb a corporate hierarchy. There are a lot of good jobs near the bottom of the pyramid for talented people. One can get paid $250,000 per year without having to manage anyone. If you don’t manage anyone you can work flexible hours and not lose sleep at night over whether or not a subordinate will complete an assigned task. The first step into management brings a radical reduction in quality of life and, typically, only a small raise. Being a COO or CEO is great (and being fired from a CEO job is even better; Robert Nardelli got paid $210 million to stop working at Home Depot) but being a middle manager is not necessarily a great job. As there are thousands of middle management jobs for every CEO or COO job the probability that a career in management will lead to one of those great jobs is tiny.

Sandberg and others posit complex reasons for women failing to claw their way slightly higher in management pyramids. Perhaps part of the answer that women, on average, do a more rational cost/benefit analysis.

[Note that the same can be said about programming jobs, albeit typically at lower wages than the ones above. To be a programmer can be heaven. To manage programmers is often hell. Why go from heaven to hell for a 15 percent raise that, after taxes, will have only a tiny effect on one’s lifestyle? If money is that important, why not do a little consulting on the side instead?]

Federal Aviation Administration cited as government agency where there is no fat to be cut

Politicians and newspapers talking about upcoming scheduled cuts in government spending are concentrating on the dire consequences from any cuts to the Federal Aviation Administration (FAA). The implication is that this is an agency with no fat and any cuts will go straight to the bone. (They probably felt that way in Spain when they couldn’t pay air traffic controllers $1.2 million per year anymore; in 2011 they started a process of competitive bidding for control tower operation and the results have been a roughly 50 percent cost saving (source).)

This gives me a chance to recycle my June 2011 posting about how three FAA employees came out to my house on two separate occasions and from as far away as Florida in order to make sure that I was surprising myself with random drug tests… of myself.  Also to point out the 2004 Government Accounting Office report that says “Historically, the modernization program has experienced cost overruns, schedule delays, and performance shortfalls of large proportions and has been on our list of high-risk programs since 1995. To date, FAA has spent $41 billion and expects to spend an additional $7.6 billion through fiscal year 2007.” Have things improved since then? This fiscal year 2013 report says “Increasing airspace capacity and reducing flight delays depend on the successful implementation of the En Route Automation Modernization program (ERAM)—a $2.1 billion system to replace hardware and software at FAA’s facilities that manage high-altitude traffic. FAA originally planned to complete ERAM by the end of 2010. However, software problems have impacted the system’s ability to safely manage and separate aircraft and raised questions as to what capabilities ERAM will ultimately deliver. FAA rebaselined the program in 2011, which pushed its expected completion to 2014 and increased cost estimates by $330 million.” Four years and $330 million over budget… but actually “If software problems persist, the program’s cost growth could exceed $500 million, and delays could stretch out to 2016.”

It seems safe to assume that the FAA is representative of other federal agencies, neither dramatically worse or better in terms of efficiency.

If the unprecedented did occur and federal spending were to be cut it would be interesting to see what these agencies would do. Companies get more efficient when revenue falls but they have to worry about competitors. A government agency with no competition could simply cut back on services delivered. On the other hand, the agency could do that even without a budget cut if they were truly indifferent to output and productivity. Perhaps it is fear of being privatized or having responsibilities assumed by another agency that drives government agencies to try to deliver services. If so, in the event of a cut they should be motivated to do as much as possible with the available funds.
