Nikkor AF-S DX 10-24mm f/3.5-4.5G ED - Review / Test Report - Analysis
Lens Reviews - Nikon / Nikkor (APS-C)


10 mm is a rather extreme focal length and some barrel distortion is to be expected here. However, at 3.1% the Nikkor shows a fairly large amount of it, certainly more than the competition. The good news is that at longer focal lengths distortion is very well controlled at around or slightly above 0.5%, switching from barrel to pincushion distortion between 14 and 18 mm.

Lenses with reduced image circles designed for APS-C digital SLRs usually show slightly pronounced vignetting. This is not really the case here, allthough there's almost a 1 stop penalty wide open, the amont of vignetting is actually moderate for such a wide angle zoom.

MTF (resolution)

The lens produced excellent center resolution figures in the lab and shows very good to excellent borders at all focal lengths, an impressive performance. At the extreme corners things are a little different though. While very good at the longer focal lengths (with the exception of 18 mm wide open), the corner resolution at 10 mm is very poor wide open and the lens needs to be stopped down to f/8 to reach good resolution figures (but only just "good").

Below is a simplified summary of the formal findings. The chart shows line widths per picture height (LW/PH) which can be taken as a measure for sharpness. If you want to know more about the MTF50 figures you may check out the corresponding Imatest Explanations

Chromatic Aberrations (CAs)

With maximum values of around 1.6 pixels at 10 mm, the level of lateral CAs (color shadows at harsh contrast transitions) can be considered moderate for an ultra wide angle lens. Interestingly, stopping down does not have any influence on the amount of CAs, and with longer focal lengths CAs drop only slightly to values just below 1 pixel at 24 mm. CAs can easily be removed in post processing, though, and some of the newer Nikon DSLRs already do this in camera (if you shoot JPG).
