7. Coma, astigmatism and bokeh

When it comes to coma correction the performance of the Sigma S 60-600 mm f/4.5-6.3 DG OS HSM is beyond reproach. Deformation of images of a diode are hardly pronounced, visible only at the shorter focal lengths where you can notice a slight elongation of the originally circular image of the diode.

Astigmatism, understood as an average difference between horizontal and vertical MTF50 function values, amounted to 3.6% and it is a very good result. When you deal with lenses with such a wide focal range as that of the Sigma S 60-600 mm you should additionally show how the astigmatism results spread on particular focal lengths. In the 60-200 mm range this aberration level is negligible, being just 2.1%; then it increases at 300 mm and at 400 mm it reaches a peak of 6.1%. Finally it decreases to 5% at 600 mm.

Out-of-focus images are very nice for a telephoto lens with such a high zoom ratio. Circles of light come with even light spread, without any noticeable local extremes or onion ring circles. We can have just one reservation, concerning a noticeably accented rim. You can also notice distinct truncation of circles in the corners of full frame but it’s an influence of mechanical vignetting which we are going to describe in the following chapter.
