Hey guys, this is my first post. I just had a few questions. I'm a HS photo student. I just bought a Canon EOS 650 (I know I know, old. But it was in mint condition and cheap!) with a Promaster 80-210mm lens. I'm trying to get my hands on a Canon DSLR, but thats another story. It's great and everything, but I would like to know why the aperture only goes between 4.5 and 5.6. I can't really take a lot of pictures I would like to, such as anything at night without a tripod. Are there any telephoto lenses out there that have a wider aperture range and fit the EOS/EF cameras (and that don't cost $621293482 )? I'll probably have a million more questions i can't think of now, so I'll post em as I get them. Thanks!
