7. Coma, astigmatism and bokeh

It would be difficult to have any reservations concerning the way the Tokina 70-200 mm corrects the coma. In the corner of the APS-C/DX sensor that aberration is completely negligible and in the corner of full frame it is slight. The tested lens deserves a round of applause, especially as it fares a bit better than the rival Nikkor.

The astigmatism correction is a bit worse as that aberration can make itself felt at all focal lengths. Still you can say its level is medium because the average difference between the horizontal and vertical MTF50 values amounted to just 11%.

You should praise also the appearance of defocused light points. The light is spread evenly, without any noticeable local extremes, and the rim on the edge is barely visible.
