I get that this is an inexpensive lens and it is a nice addition to the the standard kit 18-55 (or what ever) - but honestly I don't think it's worth it.  I am sending mine back.  I like crisp, sharp images and this little lens just doesn't do it for me.   I would suggest saving a few more $$ and getting a Sigma 17-55 2.8.  It will replace you kit lens and give much better IQ.
