Noritar 17mm f/4

Great lens for the money. Although this is a "L" lens for a full frame camera it works well with both full frame and APS-C DSLR. Focal length does change when attached to crop sensor camera to the approximate equivalent of 35mm when shooting at wide angle so keep that in mind. But the truth is it really doesn't matter too much so just enjoy shooting with this lens. It takes fantastic pictures with crystal clear details and can be used for any occasions. To portrait to landscape and anything in between. This is probably the least expensive Canon "L" lens available on the market. Highly recommended.

Super carry-around lens Canon L lenses are all superior quality and produce great images. Internal zoom and focus make this one especially nice to handle. Fast, accurate and whisper-quiet focus gives you more usable shots. Using this on my 1.6 crop 60D still provides a good wide-angle for indoor use. My 28 mm Sigma always had me backed into a corner.

The most reasonably priced L series lens that you'll find! Beautifully crafted lens. I loved looking at this lens. Immaculate construction. Solid like a rock. Better than a kit lens? Well, no, not really. The kit 18-55 mm is not a bad lens and if you look you can find one for $50. It also has a bit more range than the 17-40. Photos were sharp but not as sharp as an 18-135 base model lens let alone a nano. If you want to tell your friends that you have an L series lens here you go. They're not all that pricey and they're always available. Good, solid performer and better in low light than a kit lens. Otherwise, get an 18-135 if you're shooting crop sensor. They're better and cost less...
