Not a good comparison. You are comparing different stops with different focal lengths? For example 58 mm f2 with 35 mm f2.8. That's why your conclusion is absolutely wrong. Zeniar is an average lens. The best lens in your hand is Mir 35 mm
!thanks again. everything's right here, however my personal opinion allows bokeh to be busy, if it got a character. but that's not a science, just an aesthetic preference :)
