Re: Narutard chat thread
I'm really not too knowledgeable about film cameras either. If it's not too old though it may just have aperture controls on the camera, I have an older lens with an aperture ring but it only works on my DSLR when it's on "Auto" as well. I might be more helpful if you can post pics of the lens and camera in question.
Have you tried using any other brands of DSLR? Nikon, Sony, Pentax? I've got a (now broken) Nikon myself, I personally found it much more comfortable to hold and to have better menus than Canon.
