Zorki 4

Zorki 4

This one as all my Russian rangefinder cameras I have bought in Estonia. During a Soviet collapse Estonian people fought for freedom and achieved an indipendence after decades of occupation. Hundreds of thousands Finns rushed to Estonia to buy cheap booze and cheap cameras etc. Me among the others.


Zorki 4 is a KMZ copy or at least a modification of the Leica II. It was manufactured since 1954 to 1973. It is a nice looking camera which is capable to take extremely good pictures.

Zorki is not the "Lonely Wolf", Leica copys were manufactured all over the world after WW II when the German proprietary and patents were cancelled. In this case the manufacturing quality and the finishing is a way of Leicas but value for a price is definitely higher.

Soviet made Leica copy lenses has (if you find a good one) an optical performance similar to the originals. Only the mechanical finish of the body falls behind.

  • Weight 726g with Jupiter-8
  • Diopter correction lever
  • Self-timer

Mir (Peace) 1951-1971

Mir is a cut down version of Zorki 4. Shutter speeds are limited between 1/30 - 1/500 and B. (Zorki 4 , 1sec - 1/1000 sec +B) Otherwise Mir has same features tha Zorki. It is even considered as more reliable and easier to use.This Mir has Jupiter-12 2,8/ 35mm wide angle lens.
Somehow the Mir has a more reliable feeling ?? It is definitely my favourite of these three cameras.

Zorki 4K

Zorki 4K

Manufactured from 1972 to 1977 the last RF made by KMZ. It looked good felt good and worked well in the hand.Main difference to Zorki 4 is, 4K has a film winding lever instead of the knob. I only wish, that they had spent some more time and effort on perfecting the reliability and a design of the slow speed shutter mechanism. It has the same weakness as other Zorki (and also FED) focal plane shutter cameras. Great care must always be taken when setting slow shutter speeds otherwise damage will occur and you must absolutely remember to cock the shutter before you set the shutter speed. If you don´t do this it may cause severe damage to the shutter mechanism.
The photographic results are allmost as good as any Leica. In fact the camera is very similar to a Leica III. The manufacturing standards are not as high as on Leica but if you can put up with this, Zorki will give you a great value for you money

Jupiter 12,

A copy of the pre-World War II Zeiss Biogon 35mm lens. The rear element of the lens is bigger, than the front lens. There is a real need for the rear lens cap.

Jupiter 12 Jupiter Mushroom

Jupiter 3

A copy of Zeiss Sonnar 50/1.5. Or is it ? Some years ago I found from an old Soviet web page these costruction schemes which claims that those lenses are not of exactly equal optical contruction.

Jupiter 9, 2/85mm lens

The glass is slightly radioactive and it has a propensity to get yellow, whic this one has really done. You don't need a yellow filter with B&W film.


Btw. Why it seems to be impossible to get a close-up-picture of this lens with an ordinary camera. Strange foggy negatives ?? Active

With Digital Camera everything is OK?? ;-)
