6. Distortion

Geometric deformations won’t be a problem, no matter whether you work only with the lens or with the lens with a converter. In the first case we deal with a very slight pincushion distortion at the level of 0.28%, in the second case the aberration increases a bit and changes the sign, amounting to –0.38%. Both values are really insignificant and practically you will likely not notice it.
