7. Coma, astigmatism and bokeh

The coma control is splendid – so splendid that if I changed the position of these thumbnails randomly nobody would be able to say with a 100% certainty which diode image came from the frame centre and which from the corner.

We don’t have to worry about the astigmatism either. In the case of the tested lens it amounts to 2.9% so is really negligible.

The photo below is supposed to tell something about fuzzy images the tested lens can provide. In the case of a fisheye instrument it is rather just an interesting tidbit, showing how out-of-focus diode image, positioned in the same frame corner can be deformed.
