Hi all, am new here...currently i'm still using a nikon D50 kit. Recently there is something inside my lens a smart mark...not sure what it is but it doesnt affect my pictures so i have just stick with it. BUT i'm sick of the limitations of the lens so I would like someone to recommend me an all rounder lens (events, sports, wedding, night shots, some fashion photos? nature etc.) preferably below the 1000 range as i'm still a student and not working. Ty!
