So background info, I do a lot of head-to-head camera testing for my youtube channel, Ive done this many, many times, most recently with my 5Diii vs D750, no issues. My main lens is a 24-70 2.8 v2, but I have a V1, and my Dad has a V1 as well. Ran into issues with both BRAND NEW out of the box 7Dii's.
Yes MFA is disabled. Shooting on AI Servo, Single Square, Full High Speed Burst- 10 FPS, Av mode at 2.8, shutter speeds are usually over 1/1000, sometimes all the way up to 1/8000 depending on light. Like I said, this isn't new to me.
Results on the 7Dii's looked as per the image posted, almost all of them, unless the subject is very close. I also did a side-to-side test, both cameras missed nearly all of them.
Tonight I thought it might be the v2 lens, so I grabbed mine and my Dads v1 (24-70 2.8 v1), his 70d and my old 7D. For some tests.
Both 7Dii's consistently missed with all three lenses.
The v2 and my Dad's v1 works GREAT on my 7D and sufficiently good on the 70D, though there were some misses.
If the V2 is working on other cameras, and not any of my 7Diis, Im coming to the conclusion there could be some focusing problems with the 7Dii itself. Maybe not all of them, but the 7D whopped both of them tonight in terms of focusing accuracy with the same lenses they were using.
Ill have to return both of them and I am hoping their replacements will be better.
Just my opinion, if someone spends $1800 on a camera, it should be working right out of the box.
The requirement to have to Micro Adjust a Brand new body, to me, seems crazy.
Ill keep you guys posted, should have the next body in on Tuesday or Wednesday.
