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

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

The lens barrel is a metal cylinder, 120mm length and 64.5mm diameter. There is a problem to mount it to the DSLR camera. Difficult to find a large helicoid, which has a 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 ring to the lens barrel. Rear barrel I wrapped with electrical tape for good compatibility with helicoid. The result was a massive lens.

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

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

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