Polapan 664 Film 3yrs out of date.
Unfortunately this one didn't come off the backing paper very well !!
My first film with the Carl Zeiss Jena Biometar 120mm lens mounted on my Praktina IIa SLR in Lyon, France, March 27, 2024.
The Carl Zeiss Jena Biometar 1:2.8 f=120mm was equipped with an anti-UV 67mm screw-on filter and no shade hood.
The camera was loaded with a 36-exposure Rollei film Superpan 200 (former Agfa Aviphot 200 used in aerial photography) sensitized in the red to 760nm in the near-IR band. Rollei Superpan is coated on a maskless PET support with anti-halation layers that should be removed by two presoaking bathes before the developer.
Expositions were determined for 200 ISO using an Autometer III Minolta light meter fitted with a 10° finder for selective measurements privileging the shadow areas. Shutter time of 1/250s or 1/500s were used with aperture from the full aperture f/2.8 to f/16.

After exposure, the film was revealed using Adox Adonal (Agfa Rodinal) developper at dilution 1+25 and 20°C for 8 min. The film was then digitized 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. The RAW files obtained were processed without intermediate files in LR and edited to the final jpeg pictures. All views of the film are presented in the dedicated album either in the printed framed versions and unframed full-size jpeg accompanied by some documentary smartphone Vivio Y76 color pictures.
About the lens :
This Carl Zeiss Jena Biometar 1:2.8 f=120mm lens has automatic diaphragm preselection system (ASB Auto Spring Blende) that is operated by the IIa version of Praktina camera's.
The Carl Zeiss Jena Biometar 120mm was initially designed to cover the 6x6 format of the KW Praktisix (then the PentaconSix) (zeissikonveb.de). It was also proposed for the Praktina 35mm SLR.
About the KW Praktina IIa :
The Praktina IIa followed in 1958 the Praktina FX designed by the prestigious KW (Kamera Werk Niedersedlitz) German company in Dresden.
This specimen is the version 2 (code 110) produced at about 25.000 exemplars from June 1958 to Mai 1960. Praktina camera's were very high grade precision and quality machines much more sophisticated than the Praktica and the Praktiflex also produced by KW. Praktina was a "system" SLR 35 mm camera with a an impressive range of possible accessories and lenses including large capacity 17m film back and several motors.
My camera came with the mechanical 12-view motor and two Carl Zeiss normal lenses : a Tessar 1:2.8 f=50mm and a Flexon 1:2 f=50mm. This later Flexon lens was designed for the Praktina by Carl Zeiss Jena to modernize the old Biotar 1:2 f=58mm and to fulfill a more closer definition of a "normal lens" to the focal of 50mm. The lens is also much more compact. It was soon renamed "Pancolar" by Zeiss later on.
The Praktina has its own bayonet mount that ressemble a bit to the Canon FD mount with a locking ring on the camera body. The mount has a very large diameter. The IIa model has a new fully automatic diaphragm stop down system. With the Zeiss Flexon, the iris preset is indeed like with a modern camera.
Praktina is a completely different camera compared to the Praktica IV. The body is very well equilibrated and more compact not very far for the Olympus OM-1. The design looks particularly modern and the camera is particularly pleasant to manipulate.
The productiotn suddenlty stopped in May 1960 after the governmental decision to drop down the imposed prices of all camera's DDR by 30%! Praktina was then likely too expensive to be produced normally. As consequence, the less expensive and less performant Praktica's continued when KW became part of the VEB Pentacon.
This did this shot using automatic panorama feature of A55 Sony. It always has few stitching mistakes, but overall the feature is impressive.
With 8mm Sony lens it is about 45 deg short of 360. Too bad. I hope Sony will enable 360 in future releases.
