Meopta Meostigmat 2.1/120 is a projection lens manufactured by the Czech company “Meopta,” which makes good quality lenses. The optical design is “Petzval,” with 4 elements in 2 groups.

I’ve been looking for a Petzval lens with good swirly bokeh, sharpness, and contrast. I tried Soviet KO-140 f / 2,2 and 35KP 120 / 1.8 Petzval projection lenses, but its contrast and bokeh don’t like. Therefore I bought Meopta 120  f/ 2.1.

The lens barrel is a metal cylinder, 120mm in length and 64.5mm in diameter. There is a problem with mounting it to the DSLR camera. Difficult to find a large helicoid, which has such diameter and provides a short flange focal distance.

I try the helicoid from the Cambron 500 f/ 8 mirror lens. Which diameter is 72mm. Pulled out the insides gutted and turned helicoid.

To screw the lens into the helicoid, I took a step-down ring 72-62 and squandered his inner diameter up to 64.5mm.

Measure out the correct flange focal distance and was glued the ring to the lens barrel. The rear barrel I wrapped with electrical tape for good compatibility with helicoid. The result was a massive lens.

I also glued step-down ring 58-52 to fit the lens standard cap and lens hood in the front barrel.

I bought this lens for a portrait photo. Well, a few test photos with portraits. All samples were taken on Nikon D3100 Camera. Without post-processing. Export from RAW only.

As you can see, the sharpness is good, but not excellent, for portraits is normal.

As can be seen from the examples, the lens has a nice character. Funds for the purchased and killed mirror lens paid off.
