Tokina 50-135 f/2.8 is a tele zoom designed especially for small APS-C/DX detectors. We were curious how it performs in our next category: vignetting.

The situation is good at 50 mm. Here, at f/2.8, light falloff in corners is 18% (-0.57 f-stops) and when we stop down aperture to f/4 it lowers to 5% - a level which is insignificant.

Situation is worse for longer focal lengths but never reaches level that would make us complain about it. At 90 mm, f/2.8 vignetting is 18% ( -0.75 f-stops). And again, if we stop down aperture to f/4 it almost disappears (10%).

At 135 mm, f/2.8 light falloff in corners is 27% ( -0.91 f-stops). Here stopping down aperture to f/4 did not fix the problem and vignetting was still noticeable at level of 12%. However it almost disappeared (6%) when we stopped down to f/5.6.

In this category Tokina again won with Sigma, which at maximum aperture scored between 24% - 33%.
