Techy question for the uninitiated - my understanding of A mode is that you get to set the aperture and the camera then decides the appropriate shutter speed. If you are using non native lenses with an adapter ring, the camera body doesn't know what aperture has been set, does it? So how does it decide what shutter speed? I have been woosing out and shooting in intelligent auto which seems to do most of what I want so far. So - am I labouring under false wotsits? Should I be in A mode all the time? Why?
