Sony FE 90 mm f/2.8 Macro G OSS

7. Coma, astigmatism and bokeh

The Sony FE 90 mm f/2.8 Macro G OSS corrects coma very well. It's difficult to notice any influence of that aberration even at the maximum relative aperture and in the very frame corner to boot.

Astigmatism, understood as an average difference between vertical and horizontal MTF function values, amounted to 4.6%. We consider it to be a low level so we have no reservations in this testing category.

The appearance of out-of-focus images is good. You can notice a slight trace of onion ring bokeh due to one aspherical element in the lens's construction; also, on stopping down, there is a lighter rim which might be a bit bothersome. Still both these effects aren't especially pronounced so the circles of light look nice and well. Mechanical vignetting is a problem, though – by f/2.8 it is very distinct and it never disappears completely even on stopping down the aperture by 2 EV.
