The owners of APS-C/DX reflex cameras shouldn’t fear distortion when attaching the tested Voigtlander to them. Our measurement showed that this aberration reaches –0.79% so is not bothersome. On full frame the geometric deformations increase to the value of –1.59%. It is still low – for comparison it’s enough to mention here classic 50 mm f/1.4 devices from Canon and Nikon which can on full frame have the distortion at the level of –2%. Voigtlander features a wider angle of view and still it corrects this aberration better. Small wonder we asses very positively the lens’s performance in this category.
