8. Vignetting

Vignetting was the biggest slip-up of the extremely well done Zeiss Apo Sonnar 2/135 and its only flaw– that’s why we were very curious what the Makro-Planar 2/100 might show in this category. First let’s check the results on the APS-C/DX.

You have some chances to notice any vignetting only at the maximum relative aperture and even there its level is moderate, amounting to 21% (-0.67 EV). The problem disappears completely on stopping down to f/2.8, with the brightness loss decreasing to an imperceptible value of 6% (-0.19 EV).

Let’s check now the performance on full frame by looking at thumbnails, shown below.

At the maximum relative aperture the vignetting gets to 38% (-1.36 EV). It is a quite significant result, exactly the same as that of the Apo Sonnar. On stopping down to f/2.8 the vignetting decreases to 22% (-0.71 EV) and it becomes imperceptible by f/4.0 where it reaches just 8% (-0.23 EV).
