I really liked the lens. He draws wonderfully, an excellent portrait painter, there is no vignetting at all, almost no chromate. AF, although slow, but I have not yet had such that he smeared. I perceive the absence of a stub as an integral characteristic of Nikorov's standard high-aperture fixes. In my opinion, it is not even needed. PS I sold it due to the lack of interest in the EGF on the crop.
