Hey everyone -- complete noob here (I've only ever used a sony cybershot dsc-650). I just inherited a canon ae-1 (film camera... it's old, too) with a 35-135 mm f/3.5-4.5 lens. My problem is that when I took the lens off and adjusted the f-stops, I couldn't see the hole widen or become smaller. When I look through the lens and adjust the f-stops, it looks like it just stays on the maximum aperture. Is it supposed to be like that?? Is this a complete noob question, or is there something wrong? I'll be developing my first roll of film from it this weekend... I'll see how it turns out (probably absolutely horrible). Thanks.
