14mm Rokinon

Impressions of the 14mm Rokinon f/2.8 UWA lens on a Nikon D800 at full frame (FX). This lens is manual focus, but has a coupling chip, so the D800 rangefinder function works, as well as auto exposure. The 14mm Rokinon is extremely sharp across the field with low chromatic abberation. It does have lots of distortion, as can be seen in the un-corrected images. However, Lightroom does have a Lens Profile available for this lens, which corrects linear distortion, CA, and corner light fall-off.

Rokinon 14mm f/2.8

In use, the lack of auto focus is not an issue. The focus indication in the D800 allows focus to be set accurately even very close and wide open. Focus is very smooth, however, the focus ring has a large rotation angle from one end to the other. Build and quality seem to be very good for this moderately priced lens – it costs about 1/4 of the Nikon 14mm f/2.8 and is much smaller and lighter and just as sharp, according to the reviews. Other than being a manual focus, the only failing is the linear distortion, which is mostly fixable in LR. Overall quite a bargain.

The images below were all taken with a D800, uncropped, and sharpened in LR 90% 1.0. The images have been resized to 900PX max size. Some 100% center crops are shown at the end to show sharpness. All of the images below except as noted have been corrected for distortion.
