When we deal with an excellent image quality on the edge of the frame we know that off-axis aberrations are corrected well. One glance at the crops below, taken from diode photos, with the diode positioned in the frame centre and then in the corner, and you know the coma is a bit bothersome here. The image of the diode is deformed but this effect is not distinct and very difficult to avoid in the instruments of this class (with such a combination of fastness and wide angle).

Astigmatism won’t cause us the slightest problems for a change – in the case of the tested lens it reached only 3.7% which is a very good result.
