there will be others that pipe up on this one.

But it has not to do with aperature alone, I go by F ratios, where it is the focal length devided by aperature. hence the shorter your focal length generally the smaller but wider the field of view is. just the same if your focal length is long then your image will be big but your field of view small. hope that helps you a bit
