Rollei by Rollei
My photo walk of March 7, 2023 along the left bank of the Saône between l'Ile Barbe and the Quai Gillet, Lyon, France.
I used my recently arrived Rollei 35 camera (year 1973) and a Rollei Retro 400S (=Agfa Aviphot) 36-exposure film exposed for 400 ISO.
The Rollei 400S - Agfa Aviphot film used for aerial photography is specially sensitized in the red, up to 780nm in the near IR instead of the regular 650-680 nm limit of a normal panchromatic film. The film provides usually high-definition and high-contrast negative views. What is more, the Agfa Aviphot is coated on a thin and flat polyester base without any base color increasing the contrast as well. However to prevent the halation possible the Agfa Aviphot is coated on the backside with a black and blue anti-halation pigment to inhibit the light back diffusion (halation).
Expositions were determined using a Minolta Autometer III with a 10° finder for selective measurements privileging the shadow areas. Measuring was found consistent with the Rollei 35 build-in photometer when oriented to the zone of interest. Typically, 1/250s, was used at f/8-f/5.6 to f/3.5. Allthe vi ew were taken with a 24mm screwed Rollei filter anti-UV fitted on the Tessar 1:35 f=40mm lens with the original Rollei neoprene shade-hood.

After exposure, the film was processed using Adox Adonal (=Agfa Rodinal R09) developer at dilution 1+25, 20°C for 10 min 30s.
The film was then digitalized using a Sony A7 body adapted to a Minolta Auto Bellows III and a Minolta Slide Duplicator using a lens Minolta Bellow Macro Rokkor 50mm f/3.5 at a reproduction ratio of 1:1. The reproduced RAW files obtained were processed in LR prior the the final JPEG editions.
All views of the film are presented in the dedicated album either in the printed framed versions and unframed full-size jpeg.
About the camera and the lens:
This original Rollei 35 is equipped of the collapsible 40mm Tessar lens "Made by Rollei" under Carl Zeiss licence who designed the first 1:3.5 f=40mm Tessar lens for the Rollei 35. Original Rollei 35 were manufactured by Rollei Franke & Heideke company originally in Germany starting year 1966 then later in Singapore until 1981. Originally, the build-in CdS cell was design by Gossen and the central shutter by Compur. Diaphragm and shutter are operated mechanically by two wheels on the front of the camera. The CdS cell is coupled to both. The Rollei 35 was a miniature 35 mm camera weighting around 320g, about 100g more than the Rollei 35 LED for instance with less mechanical parts. Overall more than 2 millions of Rollei 35 camera were produced over 15 years under different versions. According the serial number (3 410 XXX) of this chrome-plated camera was produced by Rollei Singapore between 01/1971 and 06/1973 and likely after 04/1973 due to the Tessar lens "Made by Rollei" instead of formally Carl Zeiss Tessar (ref : rollei35.eu/rollei35numbers.php#r35ge). It came with its original leather pouch, the wrist strap, a Rollei soft collapsible shade hood, Rollei 24mm screw-on UV and medium yellow filters, and the original user manual.
