Meopta Meostigmat 2.1/120. Adaptation for Nikon F SLR Camera

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.

Meopta Meostigmat 120 mm f/ 2.1 Sample Photos

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.

The lens has good contrast.

Bokeh is beautiful.

Infinity test

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