I'm thinking of buying a fixed focal len with a fixed aperture and in needs of some clarifications.
Say that the fixed aperture is 1.4, can I adjust the aperture to other values by means of my camera, 'A' mode or when I use the 'P' mode?
The reason why I am confused over this is becoz I was using my friend's 70-200mm f2.8. When I was using the 'P' mode, the aperture changed to f3.5 and some other values.
I thought that since it has a fixed aperture, it will be the same throughout. So what happens if I want to use my 'A' mode?
Appreciates your comments.
