Review

LOMO x ZENIT NEW Jupiter3+ 50mm is a lens that LOMO (Lomography) commissioned Russia’s ZENIT to reproduce the famous lens of yesteryear, Jupiter3.
In conjunction with the reprint, the lens barrel appears to have been newly manufactured and is shiny, and the lens mount is the same Leica L39 screw mount as the original, but an L/M mount is included, and the minimum focusing distance of the lens has been shortened to 0.7m. The filter diameter is 40.5mm, the same as the original Jupiter3.

There are many original Jupiter3 lenses on the used market. There are black and silver barrel colors, but most of them have noticeable wear and tear due to aging. The original Jupiter3 has a minimum focusing distance of 1m.
The lens design is said to be a dead copy of Germany’s Zeiss Sonnar, and features the characteristic large curved front of Sonnar lenses.

I bought this lens second-hand from somewhere with a loose lens barrel, but when I attached it to the Leica-M using the M/L ring that comes with it, I was nervous because I couldn’t get it to infinity.
When I used the Voigtlander’s 50/75 M/L ring, it seemed like I was able to link the rangefinder correctly, so I determined that the included M/L ring was warped or had a problem with the thickness. .
However, when the test was continued, the shooting results for close-up shots almost matched the double images, but for distant shots, even though the double images matched, the shooting results were off.
When I checked the distance scale and actual focus position on the EVF, I found that the 5m index was at infinity.

It seemed to have a rather rare abnormality, so I contacted the place of purchase, and they suggested I return it because it was a defect not listed.
The lens itself was a beautiful piece, so I was a little disappointed, but I returned it because there was no point in having a lens that couldn’t be used properly.
