Sry, its a bit off topic but WHY THE HELL does it say "AE Bracketing +/- 3 EV) in almost every report I read? You can bracket up to 7 shots +/- over 8 EV, thats a lot! I was confused when I read that the 5D III had only +/-3 beacuse I thought its not better vor HDR than my 7D, but +/- 8 stops is a lot. Although I had the 6D in my handy on tuesday, I didn't check if its the same with the 6D. But it's not ok to write "AE Bracketing +/- 3EV", because it would mean its the same as for example the 7D where you can only take 3 shots up to +/- 3EV, thats it. With the 5D III its the same if you want to take 3 shots, but you shouldn't leave out that you can get a whole more EV range when you push up the shots. Whats your opinion on that?
According to the 5D3 manual (page 170), the camera brackets the exposure up to
+3 stops. This can be done with 2, 3, 5, or 7 shots. So, regardless of the number of shots, the AEB is still within
+3 stops.
It then says you can set Exposure Compensation (which is another + or -5 stops) in combination with the AEB. I am not sure if the Exposure Compensation can be bracketed (on the + and -) similar to AEB, or is it set only in one direction (darker or brighter). Perhaps those who have tried it can verify this.
In either case, the specs for 6D and 5D3 seem to be similar on this feature.
Despite all the other differences (minor or major as noted by others); for me, the biggest question is how 6D's new AF system will perform. For this, I will wait until 6D is released, tested, and reviewed....Unless 5D3 price gets closer to my budget
