Hey guys. I just got a pentax k100d, and was really excited about it. But after using it and reading it. I realized i had a few questions. I was wondering how you can tell the difference between the k100d and the k100d super. Because I'm not sure if I have the super, or normal. Next thing. I thought I read somewhere that my camera can only handle certain large f stops. like f1.4 might be to large for my camera. anyone know if there are limits to my DSLR?
