Canon EF-S 10-22mm f/3.5-4.5 USM

Review Date: Oct 25, 2005 Recommend? yes | Price paid: $700.00 | Rating: 9 

Pros: Sharp, light, focual length, USM.
Lose manual focual ring, soft at 17mm from f5 & above for this copy.

Just got this lens today. Did a little test indoor:

At 10mm is a little soft around the corner at f3.5, very sharp from f4.

At 17mm, it's very sharp at f4, but from f5-f8 is soft then sharp from f9.

At 22mm, it's very sharp at f4.5 but little soft at f8

Overall, very good lens, perfect for 1.6x crop cameras.
