This was the kit lens on my old 300D, and it fits my 20D too, is there any real use for this lens? I mean Ive tried it completely stopped down for night photography and the results were not very good. I have yet to really put it through a f11 daylight workout since it seems too finicky as to when it will decide to be sharp. contrast is also really bad with this lens... To me its worth it to use my 28-75 2.8, or even the 50mm and just walk back further.. lol Anyone have any tricks m or ideas where this lens would come in handy? I never never use it anywhere, I should sell it to someone who bought a rebel with no lens and just shoots family outings... any thoughts..? Anyone want it ?
