Zorki 4K Svema FOTO 200
A new risky test (due to quality problems) of Svema films, here the OTO 200, in Lyon France, December 26, 2022.
I used my Zorki 4K camera (year 1977) equipped the 42-mm shade hood of my Focaflex and a FOCA anti-UV filter.
Svema (Свема) OTO 200 is a super-panchromatic film coated on a very thin polyester flat base that looks very closed to the aerial film Agfa Aviphot 200. The film an extended sensitization in the red to the near IR at 780 nm,
The film was exposed for 200 ISO using a Minolta Autometer III and its 10° finder for selective measurements privileging the shadows zones of the scenes.
Typically, and due to the poor light conditions, exposures was at 1/125s or 1/60s from f/4.5 to full aperture (f/2 of the KMZ Jupiter 8 lens)

After exposures the film was processed using Adox Adonal (equivalent to Agfa Rodinal) developer at dilution 1+25, 20°C for 7min (the Rollei Superpan 200 required 8min in the same conditions) according to data found on www.digitaltruth.com).
The film was then digitalized using a Sony A7 body fitted to a Minolta Slide Duplicator installed on a Minolta Auto Bellows III with a lens Minolta Bellow Macro Rokkor 50mm f/3.5.
All views of the film are presented in the dedicated album either in the printed framed versions and unframed full-size jpeg. The negative views have of poor density and the film suffers from 2 major other problems :
1- The film is shorter than indicated since I made only 33 views instead for the given 36 exposures.
2 - Aside the first 6 views, the emulsion is damaged by darker zones and density "punctures" indicated that the stock film is likely from a stock that was poorly preserved, maybe exposed to chemical vapors or outdated (contrary to the indicated expiry date in April 2024 (batch #33). The same damages were observed the previous FOTO 400 film test indicating quality problems for these Svema films.
As for the Agfa Aviphot 200 (Rollei Superpan 200) the film is backed with a water-soluble anti halation coat that need to be removed prior to development. Three bathes of 1min with water at the same development temperature was necessary to remove the black and dark blue layer.
About the camera :
This camera was manufactured in 1977 by KMZ company ( Красногорский механический завод, Krasnogorskiy Mechanicheskiy Zavod) located in the Moscow region. KMZ also manufactured the ZENIT SLR's among many other productions. Zorki 4K was produced between 1972 to 1978 and the previous Zorki models were inspired by the Leica II since 1949. This model 'Made in USSR" is branded in roman characters, intentionally for exportation. Other Zorki 4K were also branded in Cyrillic as "Зоркий". Zorki 4K was sold basically either with this Jupiter-8 lens 1:2 f=50mm or the Industar lens1:3.5 f=50mm. The Jupiter-8 is a Sonnar Zeiss optical formula and fits to the Zorki body using the screwing M39 Leica mount.
Its was sold to me in August 2022 from Austria with its original ever-ready leather bag, a front lens cap and a small shade hood accessory Minolta D42KA. The shade hood and filter of my Focaflex also fit to the Jupiter lens (Leica standard 42 mm filter)
