Industar-50 1:3,5 f=5cm P Review
Industar-50 1:3,5 f=5cm P (russian name Индустар-50 1:3,5 f=5см П) is a lens for 35mm cameras. It produced instead Industar-22 and set up as a standard lens for SLR (Zenit), and rangefinder (Zorki) cameras. It also installing on enlargers. The lens has Tessar optical design, and its time has good features. Industar-50 is designed in the mid-50s of the last century and was produced with modifications until the late 80s. Now this is probably the cheapest lens that can be mounted and used without problems on modern cameras and perform acceptable quality.

Industar-50 1:3,5 f=5cm Handling and Mechanics
My copy of 1958 issue, as evidenced by the first two digits of the serial number. Then, the focal length is still labeled in centimeters. Issued on KMZ factory (Russia). It has a single-layer coating, as evidenced by the letter "P". Later, when all lenses made coated, the letter "P" has disappeared from the title since lost its relevance. MC version of this lens, I know not.
The lens has a small size, and on modern SLR camera looks unusual. [caption id="attachment_1167" align="alignnone" width="1200"]
Mount on Nikon SLR camera[/caption] It assembled in a shiny metal barrel. [caption id="attachment_1170" align="alignnone" width="1200"]
At the "infinity" position[/caption] [caption id="attachment_1169" align="alignnone" width="1200"]
At the MFD position[/caption] In front there is a thin focus ring. It is rotated by 270 degrees. Progress helicoid small, 5 cm. The diaphragm closes smoothly. The lens has a mount thread M39.
In version for rangefinder rear screw 10mm plastic black ring to compensate for a short flange distance. I mounted Industar-50 on the Nikon D3100 camera using a ring M39-M42 and adapter M42-Nikon. At the same time there is no infinity. Maximum focusing distance about 1 meter. You can shoot close-up portrait, but in general uncomfortable to shoot people. For Canon SLR and mirrorless cameras it can be used fully. On the Nikon F Industar-50 is good only for shooting shallow nature, flowers and so on. Lens construction allows painlessly adapt it into a Nikon with infinity safe. But while there's no time to alter it.
Industar-50 1:3,5 f=5cm Photo Examples
I mount the lens on Nikon D3100, it was curious to see the lens characters. All cite examples RAW export without post-processing. All shootings at wide-open.
This is the maximum focusing distance of the camera Nikon F.
Color render is pleasant. The contrast is normal.
I surprised, it copes with backlighting. For it age, it is normal behaves.
This is again the maximum focusing distance
And this is the minimum, the same plot
Industar-50 1:3,5 f=5cm P is a regular old 50mm lens with the "Tessar" design for amateur cameras. No more and no less. Today, because of the huge choice of lenses, special value is not.
