Hi all
I sure did try it out in "real" light.....set it up on a tripod out of the wind and did my "brick wall test"...first shot the 5d3 with same lens, same exposure etc all with 2 sec timer delay like I use in the field all the time, then the same setup with 5d4.
When I uploaded the images, the 5d4 was just slightly out of focus. So I thought, it's got to be vibration etc. so I retried it. Sure enough, still not looking good.
So then I thought it's got to be an AFMA issue. I set up my AFMA apparatus and tried. Still soft. The interesting thing was that the entire focal range was slightly blurry, but it was "clearest" on the marker indicating that the lens was not focussing either in front or behind the target, ie it actually seemed to be "on the mark".
Then I tried this again using live-view focusing. Razor sharp.
That's when I ran out of experience and knowledge and posted here. Also called Canon, tried a few things with AF settings but this did not help.
So now camera is on road back to NY....B and H was awesome to deal with, no problems at all....but with the holiday, I doubt I'll see a new one for a couple of weeks.
Too bad, since I will be in Yosemite all next week and Great Smoky Mountains the week after. I was really looking forward to shooting the 5d4 on these trips.
Luckily my 5d3 won't stop taking good pictures just because the new one's out.
I almost went with the 5DSR...........maybe I should have. But the touch screen on the 5d4 rocks, and the AF using Live View does too.
