8. Vignetting

In this category the tested lens can be in lost position at the start. Its rivals are designed for full frame, so on a small APS-C/DX sensor can perform better. How does it look in reality? Let’s have a look at the results of our measurements.

Sony DT 50 mm f/1.8 SAM - Vignetting


At maximum aperture the light falloff reaches significant value of 38% (1.36 EV). Sony comes off the worst here, although Nikkor was only slightly better (35%). Canon, on the other hand, corrects this defect the best, as its result reaches 26%. Fortunately, stopping down by 1 EV (to f/2.5) makes the vignetting fall to 20%. Almost unnoticeable situation is recorded at f/2.8, where vignetting amounts to 13% and vanishes absolutely at f/4.0 (6%).
