I bought this lens with some skepticism because of some bad reviews. The truth is that I found this lens to be an exceptionally high quality lens, with great IQ and well built. It has become my walk around lens, I have learned to appreciate the wide view provided by this focal length.

There are a lot of bad reviews about this lens. It does have it's flaws, but overall it is great wide angle lens for the price. I was in the market for as wide of a lens as I could find around the $500 price mark. And this what I took a risk after reading multiple bad reviews.

Digital SLRs like the Canon D30/D60 have sensors that are smaller than a 24x36mm "35mm" frame, and t

This is a nice little wide angle for your Canon DSLR. It is EF, meaning it's designed for full-frame Canons (series such as 1d, 5d, 6d etc) which gives optimal results. I decided to go for this wide angle purely based on budget; I have previously used a 17-40L and found that extremely good, though...

This lens has a great clarity to it, being a prime lens, and also has little distortion around the edges of the shot.

Used lens was as described: clean and in great description. The lens is a great one for landscapes and wide angle people/action shots.

Agree with the other reviewer RE crops. I'm using this on a trip and with a 7D @ 18MP I get fantastic 100% crops. This is a great landscape lens and I think a great buy if you can deal with primes.

awesome lense.

I played around with wide and ultra-wide lenses over the years. The best lens for a full frame camera that I have found is this 20mm lens. It seems to be wide without exhibiting extreme distortion. The nice part if the field curvature works well taking photos of small rooms.
