Lens class! Great for portraits, but of course I would like a larger aperture. Autofocus speed is the fastest among analogues: sigma 30 / 1.4 dn, sony sel35f18. And the picture is better, especially compared to the last one. The only thing is that when the aperture is closed, the sharpness almost does not increase, but decreases from 4-5.6. So there is no razor. But at 2.0, very good sharpness compared to analogues.
