This lens comes from the bottomless forges of the 60’s Soviet factories. True to the M39 thread mount legacy the form factor is tiny. Focus ring is near the nose, which is actually nice in use, if at first, a little bit confusing. You get pretty close, though not macro close. More like puppet animation close? How much Soviet can You be? Not much more than this. To use the lens on a Sony e-mount, You need LM-NEX and M39-NEX adapters. All in all a small package. Lens itself is like something out of a rocket before all the digital stuff. Everything is clickless. Silky smooth and not very accurate. Flares from this lens are true vintage. Something in every photo screams old. In a good way. Color reproduction is magical, there is some strange tint effect going on but I like it. Never really sharp, You get decent from f8 but whatever. I go for the look. You might get quite nice accuracy sometimes. For this ISO800 wide open shot I opted for black & white. Qualities of the lens provide some difficulties in accuracy but hands-on usability is enjoyable. Straight-on sun washes the image but You can almost rescue back contrast afterwards in edit. It leaves a nice feel to the image, I think. I find that bright sun works best. Overcast weather amplifies the lenses shortcomings. I dunno what happened here but I really like it. From old-school blown out highlights to that look You really can not get with any filter, this lens is a must. Mine cost 10€. Now that’s cheap. And there are plenty floating around. Don’t expect miracles and this lens gives You wonders. Go get one. Get frustrated and get images You could not have guessed. Beautiful.
