Input:
I couldn't be happier with the purchase of this lense.  The transaction through Amazon was flawless and it was delivered a 1 1/2 weeks earlier than expected.

This lense is so sharp you could shave with it. I now understand the image quality of an "L" lense.  If you are looking to upgrade your kit, don't hesitate on this one!!
