7. Coma, astigmatism and bokeh

The Sony FE 16-35 mm f/2.8 GM II deals with coma very well. Its influence is practically invisible in frame corners of the APS-C sensor; in corners of full frame it can be noticed as just slight enlargement of images of a diode. In this category the tested lens deserves to be praised.

Astigmatism, understood as an average difference between vertical and horizontal MTF50 function values, amounted to 6.9% and it is a level we still consider to be low. Some slight differences between particluar focal lengths are still visible because this aberration increases with the increase of the focal length: at 16 mm it reaches 3.5%, at 24 mm it is already 6.9%, and at 35 mm it amounted to 10.5%.

The appearance of out-of-focus circles of light was a disappointment. Onion ring bokeh, stemming from the fact that there are a lot of aspherical elements inside this lens, makes itself felt. A distinctly brighter centre is visible in the middle of the rings. On stopping down the aperture you can also notice a brighter rim. The correction of mechanical vignetting should be praised though – it is bothersome only at the maximum relative aperture.
