Title: Versatile lens...a workhorse!
Review: I do a lot of night long-exposure photography and this is my lens of choice. For long exposure photography, you don't necessarily need a "fast" lens so this f/4 L glass works great. Perfectly priced!PROS:- Tack sharp! (especially between f/5.6 and f/11 at night!)- lightweight for L glass- non-extended zoom- good zoom range...makes it a versatile walk-around lens during the day- excellent performer on a 1.6x FOVCF body (I used it on the XTi, 10D, 30D, and 40D). On a full-frame body, I have heard of some vignetting and soft corners when wide open or even close to it.- comes with the hood and bag (although the hood is quite useless on a non-full-frame body)- fast focusingCONS:- hood is useless on a crop sensor...still get some flare
