Technically and visually minimal vignetting at f/1.4, all gone from f/2 to smaller apertures (DX). Minor barrel distortion, very good for a lens this wide.
Sharpness at f/1.4 is fair but already at f/2 it's very good, improving all the way to f/2.8 from where it's excellent. While some say it's not good for daylight shooting I have tested it to equal detail at f/8 when compared to the mighty 17-35mm at 28mm f/8. In the same test photos, 28/1.4 had better shadow detail. (F100 and Kodak UC 200).
Paints a very smooth bokeh and gives brilliant low light color and contrast. I'm doing available light event and wedding photography with this lens and am constantly reminded by its performance in the form of photo quality appraisal from customers.
If you shoot available light, stage performances, indoor or night sceneries this is the king of your choices. Results straight out of the camera. Production ended because of the banned use of lead in the construction, only 7300 were ever made.
this lens cost me more than my car. With that said, if you shoot available light and need a wide angle, this lens is worth every penny. It is sharp at every aperture and having owned a leica m 28mm f/2 summicron for years, I have seen sharp 28mm lenses before. In the digital format, especially combined with the full frame Nikon D3, there is nothing like this lens. Canon has a 24mm f/1.4 that for me is too wide and a 35mm f/1.4 that is very sweet, but in many cases too tight.
28mm is a favorite focal length of mine and this Nikon f/1.4 version has quickly become my all around lens. Combined with the 85mm f/1.4, you have a perfect low light kit for documentary shooting.
Think the purchase through, Nikon will probably come out with a new version soon that will be around $1500, but if you need it now, the image quality is amazing.
This is an extrodnary lens, the lens provide amazing image when shooting indoors, the BOKEH is fantanstic. The image is very sharp when aperture was above F2.0. The only problem is the lens is easy to collect dusts and IT IS expensive!
This is the Prime Wide lens. There are no other lenses. Super Fast Super Sharp Pro Lens. The only dislike I have is that Nikon's list price is still about $2000. No kidding two thousand bucks.
