What People Say
After reading some reviews of this lens, I began to have doubts about its quality. After buying one, and using it for just a few days, all doubts have vanished. This is a great lens! It is as sharp as the best of Nikon’s lenses in the center, with only a slight loss of sharpness in the corners. It is almost as sharp at f/2.8 as at other apertures. It does have some coma in the corners, noticeable when photographing stars, but not too bad. Thee is some distortion, but not too bad. There is vignetting at maximum aperture on my Nikon D700, uncorrected, but with the D700 vignetting control feature, that eliminates the problem. There is very little ghosting or flare. The color rendition is excellent and the contrast is superb. AF is not lightning fast, but acceptable. All it lacks is AF-S. On a scale of 1-10, with 1 being a Coke bottle bottom and 10 being a perfect lens, I give this lens an 8.
The lens built reasonably solid with a slight play at the front barrel that doesn’t bother me. Manual focus operation is fantastic, very smooth and even well damped.The optical quality is on par with the more sophisticated pro zoom lens, its sharp even wide-open, great contrast, and very few flare & ghosts despite somewhat complex design.This lens is the most reliable companion for street and vast nature photography, thanks to the very compact design, it’s not eye-catching and will not scare the subjects off like the big chunky zoom lens, and the fast f/2.8 aperture let me shoot via street-available lights at night.
Safety concerns aside there really are a number of other advantages to short, lightweight lens when you’re running around festivals and events all day and night.
After much research on the 20mm 2.8 lens the finale outcome seemed mixed to me with most of the reviews leaning towards the “nice but buy something else”. I got one anyway for 3 main reasons:
1)I wanted small and lightweight – equal to or faster than 2.8 lens.
2)I needed an ultra wide 20mm ( somewhat wide 30mm on my camera)
3)I wanted to stay well below $1000 since I no longer work for a studio and I do this for fun and the occasional computer graphic work.
Here’s what I’ve found about this lens on my D300:
There is a little light fall off at 2.8 but not enough to mean anything to me.
It does seem to be a little soft but in looking at the images I’m noticing some back focusing.
At 2.8 the center of the image is the best as the more you move to the edge the softer you’ll get.
I got better than I thought hand-held shots at 2.8 and 1/30 to 1/60.
When the camera is held level barrel distortion is not as noticeable as I was lead to believe although it is there. If you plan on using this for professional interior/architectural work you will need some software to help remove what little bowing is there IMO.
All in all I think it is a very good lens for the money when you look at what you get which is a small, well made, fast, bright lens, with very good color and contrast.
If you can live with or I should say learn to work with the “quirky” parts, it’s a good lens.
It’s not a professional lens but I’m not sure it was ever made to be a digital pro lens.”
