6. Distortion

Telephoto lenses with this kind of aperture have practically no problems with geometric deformations, no matter whether they work on a full frame or on an APS-C sensor. In the second case, the distortion is practically on the zero level. You can see it in the picture below and it is proven by the measurements, which indicate only very slight – 0.28% barrel distortion.

The distortion will be more easily perceived on full frame. Here, its value reaches –1.03% so a level distinguishable on a test chart but not very bothersome in real life shots.
