Bjørn Rørslett says (referring to Nikkor 35 mm f/1.4 AIS) "Nikon has offered this superspeed lens for two decades now, so must believe the design is good. This is an excellent lens for low-light and general photography, although the results are not stunning when it is used wide open. Partly this stems from the tendency to internal flare that needs stopping down to f/2-f/2.8 in order to disappear. Its imaging capacity quickly increases when the aperture is set to f/2.8 and peak performance is reached between f/4 and f/5.6. In this quite narrow range it produces tremendously sharp images. To illustrate its imaging potential: In the peak range it is possible to discern objects that actually measure <1 mm within a recorded area of 5 by 8 m. You'll need at least 40X magnification to observe these tiny details on the film, but they certainly are there . This shows the unbelievable level of detail that can be resolved on film by this lens! At f/8, however, performance starts to decline and by f/16 it's just another ordinary lens. Flare isn't usually a problem with it and ghosting is well controlled, too.

The peak sharpness of the 35 mm f/1.4 lens declines towards the corners, partly because of curvature of field. Seemingly its optical design is optimised for central sharpness, which should suit PJ-style users. However, if you put this lens to use for nature photography, you do well to acquaint yourself with its sharpness distribution across the image area. For digital camera users, there is less noticeable decline of sharpness away from the dead centre of the frame.

The 35/1.4 features CRC and thus is a capable performer even up close down to its near limit at 0.3 m. There will be quite visible barrel distortion, though, when it is focused this close.

On DSLR cameras, you will observe some chromatic aberration towards the corners of the frame with nearly all models. Only the combination with D2X behaves nicely in this respect and although there is some CA, it is generally negligible (or caused by field curvature). On the other hand, D2X images are very sharp even at f/1.4 and excellent in the peak range f/2.8 - f/8. Critically sharp and contrasty images still can be had at f/16 with the D2X. Similar behaviour is seen on the D200."
