7. Coma, astigmatism and bokeh

The Panasonic Leica DG Nocticron 42.5 mm f/1.2 Asph. P.O.I.S. corrects the coma in a splendid way. The image of a diode doesn’t change, no matter whether you put it in the frame centre or on its edge. It is also not important whether you take photos with the lens wide open or you stop down the aperture. In this category the lens should be definitely praised.

The astigmatism is not a problem either. The average difference between vertical and horizontal MTF50 function values amounted to just 4.7% and we think such a result can be situated on a borderline between good and very good performance.

The defocused images can be called pleasing to the eye - it’s enough you look at thumbnails with blurred light points shown below to find out that much. The light spread is very even, without any distinct local extremes. What’s important, already near f/2.5 aperture you get the same image in the corner and in the middle of the frame.
