The comparing with the cars that Neuro made is just the same. If you are not used to drive a Porsche with manual gearbox and manual clutch and compare that with the car you are used to with automatic gearbox. Then you will decide an hour later that it is to complicated, that he is missing the contact between driver and road, but if you learn to use that car, then you will regret to step in your regular car again.
Don't get me wrong, for portraits and landscape the 6D is much better then the 7D2, but for action, no men, that will be won by the 7D2 when you can drive that car .
Here is the car comparison problem as it relates to these two bodies.
You are comparing cars.
You should be comparing a car to a pickup truck.
An action camera to a stills camera.
I found the 5DII to be more accurate for still photography than the 7D. It wouldn't be beyond possible that the 5DIII or 6D would be more accurate than the 7D II for still photography.
What this guy said.
I normally test with still objects or parts of the scenery - signs, patterns, buildings, desk items. It erases the variation in movement. As basic as it gets. The unit was a dud. No big deal, but it would have been a big problem for the canceled shoot.
I havent posted the pictures of the af errors because im not out to attack a camera, thats pointless.
However at some point ill post some 7d2 long exposure images (spot AF point) along with the 6d comparisons. They wont be anything surprising to those that do FF night photography.
