First post here.
Tried that in my 7D and no problem there. I was courious as i'm interested in the MarkIII and can't believe a 3500USD camera has this problem. In my point of view is not acceptable. For example, that would have ruined some of my long exposure pics (ex Auroras) and I don't understand how so many people call this a non-issue. For a 500USD camera maybe but for a 3500USD one...?
On my side I guess I'll wait a bit more then before commiting to the MarkIII.
And how, exactly, would this affect your long exposure shots? I just explained that this has no effect when a lens is on instead of the body cap, so unless you're shooting with a cap on, it won't change a thing :p
Dan Chung reported that the 5DIII consistently under exposed by about 2/3 stop compared to the D800. Could this be why?
No. See above.
Thanks for asking. I take most of them with the cap on, I like the look and avoids loosing time with post processing...but seriously, I've taken aurora pics where it was pitch black outside and used to check the time by lighting the LCD (while the pic was being taken). Likelly under that scenario there could have been some shift had I used the Mark3....just speculating.
No, there would've been no shift.
