On September 17 and 18, 2025, I proceeded to the first tests on film of my year-1949 French range-finder FOCA Universel and its rare OPLAR 1.9/5cm lens of the very first batch year 1948 (model-1) both constructed in Châteaudun (Eure-et-Loir), France, in the O.P.L. (Optique & Precision de Levallois) SA company factory that still exist today as a property of SAFRAN company specialized in aerospace systems.
This FOCA Universel is of the same series 1949 of the ones that participate to the Second French Himalaya Expedition 1950 to the Annapurna, that lead the two French mountaineer Maurice Herzog and Louis Lachenal to the top of Annapurna bringing above 8000m altitude two FOCA’s Universel for the historical photos. The FOCA Universel of Maurice Herzog (born in Lyon, France, in 1919) with the serial number 73.497) that came back from Annapurna, was stolen at the 1958 Bruxelles Exhibition, in the Pavillon of France. Mine has the serial number 73.058 (model-2 version-3). My camera is equipped of the very first model year 1948 of the famous 1.9/5cm lens branded « OPLAR » in good condition. Soon after, the model-2 in 1949 was rebranded « OPLAREX ».
The FOCA was loaded with a 36-exposure ADOX CHS 100 II black-and-white film that was exposed over to consecutive days, first in Lissieu Bois Dieu at the foot of the Mont d’Or massif near Lyon city, France. The film was completed the day after on the Saône river aboard my semi-rigid inflatable boat « Planète Océan » near the Island Beyne also not far away from the Mont d’Or.
Adox is one of the oldest photographic products brand in Germany since 1860. Adox CHS 100 II is a very technical film composed of a mix of two emulsions, one ortho and another panchromatic. The resulting sensitivity profile is then bit particular with a drop around 500 nm between blue and green colors. The emulsion is coated on a clear 100 micron polyester teraphtalate (PET) base with two different anti-halation layer, a black one on the film back and a violet one between the PET base and the emulsion mix. This anti-halation are removed par two pre-soaking water bathes of 2min at the temperature of the processing (20°C).. The lens was equipped with a Genaco metal shade hood 42mm push-on and either a protective FOCA AUV or Yellow filter
Expositions were determined for 100 ISO (50 with the yellow filter) using an Autometer III Minolta light meter fitted with a 10° finder for selective meterings privileging the shadow areas.

After completion to view Nr. 38, the film was processing in ADOX Atomal 49 very fine grain developer stock solution as recommended by Adox for 6min30 at 20°C plus additional 2min to compensate the developper exhaustion.
Digitizing was made using a Sony A7 camera (ILCE-7, 24MP) fitted to a Minolta Auto Bellows III with the Minolta slide duplication accessory and Minolta Macro Bellow lens 1:3.5 f=50mm. The diffuse light source was a LED panel CineStill Cine-lite.
The RAW files obtained were inverted within the latest version of Adobe Lightroom 14 (14.5, August 2025) and edited to the final jpeg pictures without intermediate file. They are presented either as print files with frame or the full size JPEG's together with some documentary smartphone color pictures.
OPLEX 3.5/9cm Test Film
This is my first test on film of the rare OPLEX 3.5/9cm produced by Optique & Precision de Levallois SA (O.P.L. SA) French company for its range-finder camera FOCA. The long focal (90mm) lens was produced for both the « Universel » bayonet FOCA mount and also for the FOCA 36mm screw mount from production year 1948 to 1963 in different models and versions. The official end of O.P.L. SA of all the photo productions occurred in December 1964.
The « OPLEX » branding was specific of the last series of 3.5/9cm for the FOCA Universel with a specific black anodized finish (model-5). OPLEX 3.5/9cm is considered as a very rare lens of about 200 units only produced in 1962 and likely a hundred in 1963. I found this one by chance at the last photo fair of Saint-Bonnet-de-Mure, France, sept. 2025. The lens is in a pristine condition but a careful examination of the front three screws shows some marks, indicating that he lens was probably serviced in a more or less long past.
I mounted the OPLEX 3.5/9cm on my second FOCA Universel RC body for a test on film using a Rollei Superpan 200 (Agfa Aviphot 200). The Rollei Superpan 200 is the same film formula as the Agfa Aviphot 200, a super-panchromatic film further sensitized in the red and near infra-red up to 750nm. The film is coated on a clear polyester base (polyester teraphtalate, PET) with anti-halo layers that dissolve into the developer during the film process. This type of film is particularly efficient to differentiate the vegetal species and the clear in part the atmospheric haze and was used typically for aerial photography.
The film was exposed over two consecutive days on sept. 29 and 30, 2025 during two small hikes in the Mont d’Or massif next to Lyon city, France. The weather was pretty and clear and I used for all views the 42mm push-on FOCA yellow filter with given coef. x2.5. Expositions were metered for 100 ISO to compensate the light absorption of the yellow filter (not the x2.5 value). Metering was done using a Minolta Autometer III equipped with a 10° finder for selective measures privileging the shadow areas.

After the last view (Nr. 38) exposed, the film was fully rolled tback to the cartridge and was developed in a Paterson tank using 350 mL of Adox Adonal (Agfa Rodinal) developer prepared at the dilution 1+25 and the film processed for 8 min at 20°C.
Digitizing was made using a Sony A7 camera (ILCE-7, 24MP) held on a Minolta Auto Bellow III equipped with a Minolta Macro-Bellow lens 1:3.5 f=50mm and a Minolta slide duplicator. The light source was a LED panel CineStill Cine-lite.
The RAW files obtained were inverted within le latest version of Adobe LightRoom Classic (Version 14.5 of Aug. 2025) and edited to the final jpeg pictures without intermediate file. They are presented either as printed files with frame or the full size JPEG together with some documentary smartphone pictures.
The results show that the best infinite focus is not obtain for the normal infinite position of the lens, but instead shifted between the marks «10-20 m » on the distance scale. The origin of this shift is unknown and should be compensated. Using the depth-of-field scale, the real distance should be read at the mark « 22 » on the right.
