7. Chromatic and spherical aberration

Coma is not a serious problem as its influence in corners of the APS-C/DX sensor remains very slight, no matter what focal length you apply. In corners of full frame that aberration becomes more distinct, especially at 70 mm, but even there you can't call it high. It is medium at the most.

Astigmatism, understood as an average difference between vertical and horizontal MTF50 function values, was 7.3%, a moderate level. We also didn't notice any differences between particular focal lengths even though officially the lowest result we got at 70 mm.

Defocused circles of light are far from perfect. You can complain about slight onion ring bokeh, visible inside the circles. Most probably it is caused by the presence of as many as four aspherical elements. A bit lighter rim makes itself felt too – its intensity increases on stopping down. It would be also difficult to pass over mechanical vignetting, visible by f/4.0 and f/5.6.
