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

The lens has been great so far and performed very well. The images do have a soft focus when using the maximum aperture f/2.8.

Lightweight; quick focus

Soft focus

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

I purchased this lens used (1 month old )and was a little cautious about it's value.Took some pictures and was very pleased.Having other wide angle Len's to compare with 24-105,24-85 and17-40 I can say this 20mm lens is as good or better tan most of the other lens.I like the build quality and how...

build quality; sharp; light weight

If you were actively seeking a review of this lens, the chances are that you've already seen another one written by Mr Ken Rockwell, who I believe it's fair to say divides opinion on many photography matters.

Fast and accurate focus; sharp frame centre; attractive colour rendering

Soft corners; field curvature; colour fringing

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.

I bought it to use with my Canon 5D Mark III for street photography and the occasional landscape. Very true colors and little distortion (nice) but serious vignetting, especially noticeable in the landscape shots.

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...

Utilisant le plein format plein depuis peu , avec un 6D je viens de compléter mon zoom EF 24-70 mm f :4 IS avec ce 20 mm f: 2.8 dont la définition et le piqué sont excellents dès 2.8 et l'on peu travailler avec l' hyperfocale très utile avec cet optique
