The focusing of the lens is smooth. The focusing ring rotates 180 degrees, the front lens does not rotate when focusing. The lens itself is very small. Its shiny white metal frame looks very unusual on modern digital cameras. There is a modification of the lens in a black frame of the body, as well as a modification with a Kontax-Kiev mount. You can see what the 'P' version looks like Jupiter-8 1: 2 F = 5cm P. There is also a similar lens, but with a larger aperture - Jupiter 3.

The diaphragm has 9 blades. The iris control ring rotates smoothly, without stopping at fixed values. At closed aperture values, the lens gives almost even circles in the blur zone.

Sample photos on Jupiter-8 2/50

It’s a pity, I don’t have the opportunity to use Jupiter-8 2/50 on mirrorless cameras. On SLR cameras Jupiter-8 2/50 works only in macro mode, in more detail here. How to use Soviet old lenses on modern Nikon cameras read here, and on Canon here. I shot on Canon 350D and two adapters M39-M42 + M42-Canon EOS.

After I crawled on my knees near the first spring flowers and transferred the photo to a computer, I was shocked by the unusual picture of this lens. The lens has amazing bokeh. On F / 2.0, weak sharpness and strong aberrations, this allows you to convey unusual volume, style and artistic content in photographs.

The history of my copy from the owner of the lens:

The lens has a slightly tired look. He had a very rich past. Its previous owner, with the Zorkiy-4 camera, was, and now alive and nimble, my grandfather, a former investigator in especially important cases of any very criminal kind. The lens had to see such that we mere mortals and think terribly. Where only he was not and where only he was not worn. From the 64th to the 84th they used it regularly. He never saw the hands of a master and prevention. But for the entire time of its operation, he was treated very carefully! But time has taken its toll. Shutenko Andrey.

Review Addendum

I came across another copy, this time with a name in Latin - Jupiter-8 2/50... Externally, the lenses are identical. Photos taken with Nikon 1 J1, With EGF lens is 135mm (sounds scary).

How to use with modern cameras?

Lenses with an M39 thread (for rangefinder cameras, M39 X 1/28.8), such as the lens from this review, are very easy to use on almost any modern digital camera (both SLR and mirrorless), for this you just need to choose the right adapter (adapter). There is no need to carry out any additional actions to remake the lens. The cheapest adapters can be found at Aliexpress.com.

For mirrorless cameras

  1. SONY: For cameras with 'E'/'FE' mount series SonyNEX и Sony Alpha need here is an adapter M39 -Sony E (aka L39 -Sony Nex).
  2. OLYMPUS / PANASONIC / KODAK / XIAOMI: For cameras with a bayonet mount Micro 4/3 (Micro 4:3) need here is an adapter M39-Micro 4/3.
  3. CANON M: For cameras with Canon EF-M mount need here is such an adapter M39-Canon M.
  4. CANON R and RF-S: For cameras with Canon RF mount need here is such an adapter M39-Canon R.
  5. Nikon 1: For cameras Nikon 1 Series need here is such an adapter M39-Nikon 1.
  6. Nikon Z: For cameras Nikon Z series (FX/DX) needed here is such an adapter M39-Nikon Z.
  7. FUJIFILM X: For cameras with mount X need here is such an adapter M39-Fuji X.
  8. FUJIFILM GFX: For medium format cameras G-mount need here is such an adapter M39-Fuji GFX.
  9. SAMSUNG: NX mount cameras require here is an adapter M39-Samsung NX. There are no adapters for the NX mini camera yet.
  10. SIGMA / PANASONIC / LEICA: For cameras with L mount need here is such an adapter M39-Leica L.
  11. LEICA: For cameras with a bayonet mount Leica M need here is an adapter M39-L / M.

It's important: for SLR cameras, only macro mode is possible (can only shoot at very close focusing distances).

For SLR cameras (macro mode only)

  1. Canon: For cameras Canon EOS with bayonet mount EF / EF-S need here is an adapter M39 -Canon EOS.
  2. NIKON: For cameras Nikon DX / FXas well as for cameras Fujifilm и Kodak with Nikon F mount needed here is such an adapter M39 -Nikon F (some cameras will only work in M-mode).

Jupiter-8 2/50 is a very interesting and well-made rangefinder lens. Will work best on mirrorless cameras. On SLR cameras it can only work in macro mode. The lens has a very specific bokeh. I recommend it for creative experiments.

  • Mark

    Hello, thanks for the review. Tell me, if you put Zenith 39 through the M42-M122 adapter, will it work?

    • B. R. P.

      No. This is a rangefinder lens. Written at the beginning of the review.

    • Andrii


  • R'RёS,R ° F "RёR№

    Hi all! Anyone who shot with this lens, please tell me. Have you used macro rings? Is it worth installing them and how many?

    • Arkady Shapoval

      The number of rings (their length) depends on the magnification factor you want to obtain. Whether it’s worth it or not depends on what you’ll be shooting.

      • R'RёS,R ° F "RёR№

        As I understand it, sketches like yours were taken without rings! What is shown in Vladlena’s examples, is this already with macro rings?

        • Stanislas

          I installed it on my Rebel XTi “I61”, a rangefinder, through 2 sets of magnifying rings for Zenit. The multiplicity is stunning to me. Especially for handheld shooting, and I don’t have a tripod. But the aperture also drops. Although for such a lens I think this is not fatal. But the depth of field is outrageously small)) I take photos handheld, and therefore there are a lot of mistakes, especially moving targets))) but that’s the beauty of photo hunting.

          • Rodion

            I highly recommend Vega-11U for such purposes. I-61 is much, much inferior to it specifically in macro.

    • Rodion

      Can you at least tell me what camera you are going to put the lens on?

      • R'RёS,R ° F "RёR№

        I have a Nikon crop!)

      • R'RёS,R ° F "RёR№

        It is clear that this is exclusively creative “pampering”). Just wondering, does it make sense to put macro rings on it, or is it better as an independent thing?

        • Rodion

          Even without rings, it will already have a very short focusing distance, if we are talking about Nikon F. If you really want, you can additionally buy a set of Soviet M42 macro rings, but, in my opinion, this lens is not one of those that can work at large macro scales maintaining reasonable image quality.

          • R'RёS,R ° F "RёR№

            Thank you!)
