LOMO RO501-1 F = 100 1: 2 MADE IN THE USSR
In short
LOMO RO501-1 F = 100 1: 2 - the old Soviet (MADE IN THE USSR!) Film projection lens. Like most such lenses, it lacks a focusing mechanism and device aperture. LOMO RO501-1 F = 100 1: 2 is one bare lens unit.
LOMO PO501-1 F = 100 1: 2 has low sharpness and suffers from strong chromatic aberrations, is afraid of flare, yellow / green. Moreover, it has its own characteristic pattern. One of the main uses is portrait photography.
For practical use as a photo lens, LOMO RO501-1 F = 100 1: 2 should be upgraded. The owner of the lens independently made a focusing cup made of a medium format macro ring and adapter KP6 / Nand macro ring M42. Specify details in comments.

UPDATE: LOMO RO501-1 F = 100 1: 2. Supplement reader Radozhiva
LOMO RO501-1 F = 100 1: 2. LOMO RO501-1 F = 100 1: 2.
The projection lens PO501-1 100/2 can be converted into a dual-diaphragm (the procedure is largely like this): it is relatively easy to install both the aperture and additional lens diaphragms. In this it compares favorably with a colleague with a smaller focal length - PO500-1 90/2. Let me remind you that the second aperture, installed behind the lens unit, is the key to control the lens vignetting, and with it, the bokeh control. Principle of operation given in this article.
The second aperture didn’t really interfere with this lens: even a slight shielding of the rear group of lenses significantly increases the contrast of the image along with a slight darkening of the edges of the image and twisting of the bokeh. In this mode, the geometric vignetting, which cuts off the "extra" rays, is deliberately introduced in photographic double gausses (Helios lenses, for example) by optical engineers. With further covering of the zalinsovy diaphragm, an increase in the depth of field and sharpening is observed - the diaphragm starts to work akin to the aperture.
The achievable effect is demonstrated by the following examples (photos taken on Sony A7s). Change in the overall contrast and the depth of field of the lens with the gradual closing of the zaliznoy aperture:

Contrast correction by invisible vignetting:
Changing the picture with covering the lens diaphragm:
A few more (since the lens has already found its owner) photos from the full-frame Sony A7s are given below.
A larger number of examples were obtained earlier on camera Canon 600D:
In my experience, the moderate geometric vignetting mode is optimal when using this lens, especially on crop cameras. Strong vignetting mode can be successfully applied to emphasize the middle of the frame and more pronounced curl of the background.
Thank you for your attention, Eshmakov Rodion.
You will find more reviews from readers of Radozhiva here.
Yes, like nothing so sharp, the contrast is only bad
Interesting bokeh, it does not reach Jupiter-9, but I put a plus sign to the lens designer and Konstantin Puchkov for revision!
A very nice picture, and the contrast can be tightened in the editor.
definitely an interesting portraiture if money is not enough for 9 Jupiter) or something more expensive
so with a rework it will come out more expensive, or you don’t put your work into anything?
really nice glass
… I see pictures and I am surprised. Good picture. Well done.
Beautiful photos are obtained, and the bokeh is pleasant.
EXCELLENT LENS, AT MY LOOK THE ONLY LACK OF IT IS ITS WEIGHT
At the Lensclub, using this sample photo, you showed the operation of the L-53 75 mm f / 2 lens. . . And here you brought a shot, as an example for LOMO RO501-1 F = 100 1: 2. . . . . . What to believe!? Question to you. So with what lens is the girl in the yellow jacket shot? :-)
Yurchenko Ivan, please answer with what lens the girl in the yellow jacket is photographed.
Sorry, I was wrong then, the picture was taken on the Zh-53
BEAUTIFUL PICTURES, THE ONLY LACK OF THIS LENS HIS WEIGHT!
In terms of sharpness, it turned out fine, the bokeh also does not lag behind, but the weight is too heavy. The bokeh just surprised me, it is especially suitable for shooting winter portraits near the lights of lanterns and garlands.

How to make it for Nikon?
Please indicate at least something (=
Complete freebie. There are two options - simple and cheap, but uncomfortable; and very expensive, comfortable and quality.
The first one involves glueing a tube made of paper and epoxy and sticking a Nikon bayonet to it (M42-Nikon adapter, for example). Focus with trombone.
The second option is to make a drawing and spend ~ 3-10 kilorubs (depending on greed and the degree of complexity - and hence ergonomics) on a duralumin helicoid.
Blue HA just enrage !!!
Hello, there is Lenkap F = 10cm, why can I use it?
Please tell me whether it is possible to polish the lens to the outside? And how to do it if possible? Thanks.
Absolutely unreal - it will be even worse and much
HA vile.
And so - very much even quite.
Add contrast, and there will be a characteristic glass for “special” portraits.
