Okay, thanks to both of you. I'd have a look at eBay and see if that Dandelion or Euro EMF programmable chip previously mentioned can be shipped to where I'm at.

The McNamara fallacy, named for Robert McNamara, the United States Secretary of Defense from 1961 to 1968, involves making a decision based solely on quantitative observations and ignoring all others. The reason given is often that these other observations cannot be proven. (See the example below.)
It refers to McNamara's belief as to what led the United States to defeat in the Vietnam War—specifically, his quantification of success in the war (e.g. in terms of enemy body count), ignoring other variables.
The first step is to measure whatever can be easily measured. This is OK as far as it goes. The second step is to disregard that which can't be easily measured or to give it an arbitrary quantitative value. This is artificial and misleading. The third step is to presume that what can't be measured easily really isn't important. This is blindness. The fourth step is to say that what can't be easily measured really doesn't exist. This is suicide.

"There is terror in numbers," writes Darrell Huff in How to Lie with Statistics. And nowhere does this terror translate to blind acceptance of authority more than in the slippery world of averages, correlations, graphs, and trends. Huff sought to break through "the daze that follows the collision of statistics with the human mind" with this slim volume, first published in 1954. The book remains relevant as a wake-up call for people unaccustomed to examining the endless flow of numbers pouring from Wall Street, Madison Avenue, and everywhere else someone has an axe to grind, a point to prove, or a product to sell. "The secret language of statistics, so appealing in a fact-minded culture, is employed to sensationalize, inflate, confuse, and oversimplify," warns Huff.
Although many of the examples used in the book are charmingly dated, the cautions are timeless. Statistics are rife with opportunities for misuse, from "gee-whiz graphs" that add nonexistent drama to trends, to "results" detached from their method and meaning, to statistics' ultimate bugaboo--faulty cause-and-effect reasoning. Huff's tone is tolerant and amused, but no-nonsense. Like a lecturing father, he expects you to learn something useful from the book, and start applying it every day. Never be a sucker again, he cries!
Even if you can't find a source of demonstrable bias, allow yourself some degree of skepticism about the results as long as there is a possibility of bias somewhere. There always is.
Read How to Lie with Statistics. Whether you encounter statistics at work, at school, or in advertising, you'll remember its simple lessons. Don't be terrorized by numbers, Huff implores. "The fact is that, despite its mathematical base, statistics is as much an art as it is a science." --Therese Littleton
Nikon has lowered its estimates for sales volume, sales amount, and operating income downward for the entire fiscal year, which ends on March 31st, 2014. Reasons for this include slow economic recovery worldwide, even worse compact camera sales than predicted, and slowed growth in mirrorless cameras.
The actions that Nikon is taking to improve the situation include:
- 'Accelerating shifting newer products in the entry class of DSLR'
- 'Reconsider product planning of Nikon 1. Nikon 1 represents the majority of sales volume reduction of 550,000 interchangeable-lens type digital cameras'
- 'Revise development plan for new compact [cameras]. Although our market share had been expanding in recent years, sales volume will diminish more than the estimated market shrink. Will maintain profitability as is.'
Please note that the tests results are not comparable across the different systems. This does also apply for the new EOS tests based on the EOS 50D because of differences in the sensor system (e.g. AA-filter) as well as different RAW-converters.
Miyanari: “Even new EF lenses equipped with USM and STM that
had fast AF drive already, it could be proven that they were even faster,
and amongst the lenses that supported Dual Pixel CMOS AF, in particular
lenses developed awhile ago, and low priced lenses, you will find that the
effect of Dual Pixel CMOS AF is quite significant.”
Has anyone seen any videos of the auto focus continuous?
I want to now how well it would do with a constantly moving subject like a bride walking towards you down the aisle.
