Summary: What a little jewel! I ran into an online review saying I have to get a copy for my full frame camera. Apparently it has a problem with vignetting, but modern cameras including my 6D come with software that automatically corrects for it, so you can't tell.
Excerpt: I absolutely love this lense. It is just wide enough that it doesn't distort my image quality, yet is very versatile. I use it for landscape shots around NYC and have already printed multiple images.
Excerpt: 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.
Excerpt: This is becoming my new 'favorite' lens. First it's 2.8 so it's pretty fast. On my 7DMII, crop sensor it gives a little step back, which is great for architecture and landscapes. (90 degree field of view) Note: This is not a portrait lens, not for closeup people photography.
Excerpt: Very flexible and sharp - versatile, light and sturdy. we are using this for a special teaching video shot under hard circumnstances on location and hot and dusty environments.Gives excellent results!
Excerpt: 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...
Excerpt: I shoot this as a wide on 7D. With full frame one day, I'll review again. Right now I like the results I'm seeing. This lens is easy to use, gives consistent very good results, is sharp and I'm not seeing obvious distortion, CA etc.
