hey djus, thanks for the comment.you're right, i'm having a hard time with the 70mm end, that's why i am thinking of an all around lens, though, the f/2.8 will be a great loss for me if i'm gonna ditch the sigma.sharpness is also a problem in the 200mm end. if i can't get 18-200mm, i might just have to wait to get myself 24-70 f/2.8.don't know, we'll see. thanks

hey ricky martin,i don't know what the f**k you are talking about...
