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

Bought this secondhand a few years back and it's probably been my primary lens since. The only thing I wish for is the weatherproofing, but given the cost and size, I'm happy to use a shower cap. I find it sharpest at an apature 7-9

Another great lens, wide angle. Great build and sturdy

Being a keen church bell ringer and church visitor I appreciate the ability to get wide view from close range such as the interior of belfries using the 10mm focal length. The wide aperture is advantageous for low light in similar locations. Being able to zoom in close with the 22mm focal length. Similarly for landscape photography I can get much wider appreciation of the scenes before me. All images are crisp and tonally correct. Light weight for its size and comfortable to handle.

Good Points: It's a UV filter it does what a UV filter should do what more can be said? Improvement Points: Cost.

Great wide angle lens for a small price. Works well for majority of landscape including using a Cokin P system. The slight curve on the front lens does protrude slightly so you need to watch out for vignette great.
