7. Coma, astigmatism and bokeh

The thumbnails below show clearly that, when it comes to coma, the Tamron performs very nicely indeed. Even in the corners of full frame and at the maximum relative aperture the image of the diode remains circular; the deformations are practically imperceptible.

The astigmatism, understood as an average difference between horizontal and vertical MTF50 function values, amounted to 3.2% so was low. It would be difficult to see it even near the maximum relative aperture.

Circles of light, generated by the Tamron in out-of-focus areas, are very pleasing to the eye. Here Tamron managed to outperform even the results we saw in the 1.8/45 and 1.8/35 models – not even a trace of any onion rings.
