Just wondering on this issue..
currently i have a 20d paired with a 17-40L
what other lenses suitable for this part of photography..
i do know that 70-200 f2.8 or f4 is a so called "industry standard" among many photographers...but damn expensive uh...
how about primelenses?wat is a preferred focal length for cropped bodies?85mm?135mm?50mm?
i was thinking of getting a 2nd hand 40d/50d as a main camera and my 20d will be a back up so as to minimize lens changing on 1 body.,.
