Q: If I set the lens to let's say f2.0 and put the 5DII in Av mode, will the camera get the right speed to match the correct exposure by itself?...or I'd be condemned to use it on M mode.
A: You can set the camera to A mode and it will expose more or less correctly. It will work, but if the exact right exposure is important to you you'll need to find out at what aperture openings some exposure correction will be needed. That's easy to do, sometimes harder to remember.
