Sony FE 35 mm f/1.4 GM

7. Coma, astigmatism and bokeh

As in the case of the Sony FE 35 mm f/1.8 we had some reservations concerning coma correction in corners of full frame, here the performance is simply sensational. Even at the maximum relative aperture and in the very corner of the bigger, full frame detector coma is difficult to notice and point-like diode images keep their circular shape. A round of applause!

Astigmatism, understood as an average difference between horizontal and vertical MTF50 function values, amounted to just 1.4%. It is a negligible level that shouldn't bother you at all.

The appearance of out-of-focus images is very nice, with smooth light spread in circles. Onion ring bokeh doesn't make itself felt despite aspherical elements; a brighter rim that appears on more significant stopping down is not especially intensive. Mechanical vignetting is clearly visible for a change but only by f/1.4; by f/2.0 it becomes marginalized and by f/2.8 it disappears completely.
