Jupiter 8 50mm f/2.0 lens on Sony NEX 6

This is a short post about using an M39 mount Jupiter 8 50mm manual lens on the Sony NEX 6 camera with an E-Mount to M39 adaptor.

Jupiter 8 Description

My Jupiter 8 is the only m39 manual lens I own that I actually know the history of. It was fitted to a Zorki 4 camera which my father bought from new in the 1970’s and which I acquired a couple of years ago when he gave it to me. Consequently it is in the best condition of any of the soviet era lenses which I own.

It’s a very small lens, which I suppose is typical of m39 lenses, with a filter diameter of only 40.5mm and a length of about the same. The focal length is 50mm which means it becomes a short telephoto lens on my Nex 6 when the crop factor is taken into account. Because it was originally made for a rangefinder camera, the registration distance (the distance from the back of the lens to the film plane or sensor) is quite short which means that for my Nex 6 it has a much slimmer adaptor than any of the lenses I have which were made for SLR’s. When fitted to the Nex it makes the whole package very small and light.

The aperture range of f/2.0 to f/22 has no click stops so can be set to any value within that range. The aperture itself is 8 blade, so fairly circular as it stops down.

The pictures taken with this lens have a 1960’s ‘soft’ look and any background defocus has the characteristic swirlyness which people come to expect in lenses made in this era. When stopped down it becomes a bit sharper, but it never has the definition of, for example, the takumar M42 28mm or the Pentax K-Mount 50mm I own. The sample images below were all taken a few days ago in Stevenage and have been post-processing in Lightroom.

  1. Hi Simon

    What a fantastic site: I’ve only been perusing for a few minutes but have learned a lot about tying to hitch old glass to the front of my Fuji XA1 and X-Pro. I think I’ll be back.

    I’d like to dip into your knowledge and hope you can help. I have a couple of Meyer Optik lenses (a Lydith30 mm and a Domigor 135) both boxed and in excellent condition but with the breech type mounting. They are too much of a challenge for me and I wonder if you know anyone that might want them.

    Warm Regards

    1. Well thanks for the kind words David. I would check on eBay to see what sort of price you could get for your lenses if you don’t want to keep them, or you could probably get a mount adaptor and try them out. Meter-Optik were quite a good make – they became Pentacon. I would guess that the mount is probably exakta ?

      1. Many thanks for the really prompt reply.

        I’d love to keep and use these lenses but the mount is the problem. Here’s a picture of the camera end of the 135mm (Domigor) ( http://www.google.co.uk/imgres?imgurl=http%3A%2F%2Fwww.rockycameras.com%2Fekmps%2Fshops%2Frockcameras%2Fimages%2Fpentina-domigor-135mm-f4-prime-portrait-zebra-lens-19.99-%255B3%255D-29247-p%255Bekm%255D160x120%255Bekm%255D.jpg&imgrefurl=http%3A%2F%2Fwww.rockycameras.com%2Fpentina-domigor-135mm-f4-prime-portrait-zebra-lens-1999-29247-p.asp&h=120&w=160&tbnid=vdIV51virxRdwM%3A&zoom=1&docid=_roB4RubF4XyRM&ei=5n01VIupAe2u7Aa854HIBQ&tbm=isch&ved=0CCgQMygHMAc&iact=rc&uact=3&dur=572&page=1&start=0&ndsp=34 ). It is a breech lock mount and, sadly, I can’t track down anyone who makes an adaptor to a Fuji X mount.

        I’m going to keep on looking but think I will have to let them go to anyone who uses a Pentina camera.

        All the Best


        1. Good afternoon Both

          I passed the lens on to a dealer in the west country – there is a much better chance of finding a good home for them that way.

          The Lydith came in a box and , underneath was the original price – £25 10s 6d – a fortune in the 60s and probably the equivalent of £25 now.
