The Streak Continues: 333<\/h3>\n

Yesterday was a day of trying to deal with the challenges of transitioning from a PC to a MAC after a lifetime of the former…. This blog post, the 333rd in a row, took me about 2 1\/2 hours to prepare. It was published at about 7:15am from my home at Indian Lake Estates, FL. <\/p>\n

After getting back from a morning photo session down by the lake Jim informed me that this was the first blog post inadvertently published without a title. That was rectified at 8:37am \ud83d\ude42<\/p>\n

Image C<\/strong><\/h2>\n<\/td>\n<\/tr>\n<\/table>\n

Image C<\/h3>\n

Image C was created with the EOS-5D Mark III.<\/p>\n

Thoughts<\/h3>\n

If the premise that the images from the 3 camera bodies cropped to the same subject size would be easily distinguishable with the 5D III image showing the best image quality and the greatest detail and the 7D II image showing the worst image quality the rankings would have unanimously looked like this:<\/p>\n

A: 1D X
\nB: 7D II
\nC: 5D III<\/p>\n

Having seen the converted RAW files I would have rated image C as best by a slim margin with images A and B pretty much equal. Even at that, to my eye all three JPEGs looked pretty darned good. <\/p>\n

Results<\/h3>\n

Amazingly, to me at least, eleven folks nailed the test, whatever it was worth, rating image C–from the 5D III–as best, image A–the 1D X image–as next best, and image B–from the 7D II–as the worst of the lot. That said, six folks thought that image C was the “worst” by assigning it to the 7D II. Several folks felt that the images were either very close or virtually indistinguishable. All of the above of course assuming that folks understood the issues involved…. <\/p>\n

Nick, commenting on a similar post here<\/a>, stated that the “test” (my quotation marks) made no sense nor could it provide any valid information. I have no clue as to whether he is right or wrong but he seemed to know what he is talking about. <\/p>\n

Conclusions<\/h3>\n

#1: As I have stated here many times, I simply do not have a good eye for fine detail. Why do I say that? Many folks in addition to the nine who nailed the test clearly identified the 7D II image as having the poorest quality.
\n#2: With more than a few folks feeling as I did that the images were quite close in quality, the 7D II is a seriously good, reasonably priced digital camera body that produces quality images while offering great reach via its 1.6X crop factor sensor.
\n#3: Bogus or not, the test was lots of fun and led to a wonderful exchange of ideas. Flawed or not, I will look for a way to repeat it with a cooperative avian subject.
\n4: For the most part, I will go back to doing what I do best: make good images. And my plan for the immediate future is to continue using the 7D II for nearly all of my photography. Those who see me as a shill for all things Canon need to ask themselves, “Would he be choosing and using the 7D II while keeping his 5D III and his two 1D X bodies in the bag?”<\/p>\n\n\n\n

This image was created on the 2013 Galapagos Photo-Cruise with the hand held the Canon EF 200-400mm f\/4L IS USM Lens with Internal 1.4x Extender<\/a> (with the internal TC engaged at 560mm) and the Canon EOS-1D X<\/a>. ISO 800. Evaluative metering +1 1\/3 stops off the light blue water: 1\/2000 sec. at f\/5.6 in Manual mode was about 1\/2 stop too dark. AWB. <\/p>\n

Central Sensor\/AI Servo-Surround\/Rear Focus AF barely caught the petrel’s right wing as originally framed and was of course active at the moment of exposure.
