Can't find a single good review for this lens. Does anyone have it here? I guess tragic flaw of this lens is NOT having focus ring. You are also so close to subject that traditional flash sort of lighting won't work and Mitakon doesn't have tiny LED ring light for it (which makes me think it could be a fun little DIY project to make tiny LED ring). Mitakon lenses in general aren't epitomes of IQ but I would still like to hear any opinions from members.
