ah! woops lol I totally didn't see that post. I kinda noticed that I have to use at least 1/40s exposure while shooting with my nifty fifty to get sharp images that's one of the reasons why I don't use it often.



Anyway I was reading some reviews the other day and in one of them the author actually compared the image quality of the 18-55mm kit lens with the much more expensive 17-55 IS USM lens and it really surprised me how crappy that kit lens really is.
Just scroll down and you will see the pictures:
