range limit on AEC
I don't normally need too much AEC and the + - 2 range of the 5D2 is sufficient most of the time.
But there are time that I want to try something different or just to test out something. Then I wish I have more range.
The problem I have is that, there is no good reason that I can think of that cause them to limit the range.
Why the top LCD and the view finder can display shouldn't be the limit (like in my 550D, where it can go to + - 5 (or 7, I forget) even if the view finder only can show up to + - 2.
AEC should just linearly adjust the shutter speed (until I hit max or min) when I use it in Av.
Why do they have to limit this?
Manual exposure mode?
