Fine glass. The sharpness is amazing. In my opinion, it is great for studio shooting with pulsed light, although I am not a specialist in this area, I have little experience, but on the street in good lighting it gives an excellent, sharp picture, when the light decreases, you naturally have to open the aperture, the depth of field decreases, for someone this may seem like a disadvantage. Summary: a cool portrait lens, covers all the needs for this by 99.9%! For standard use, the angle of view is small, but if you are not too lazy to move, it’s quite!
