Despite the optical off centering of my Kodak Retina IIa seen with a first test film, I thought that the camera at f/16 would accommodate this problem. I loaded a Rollei Retro 400S film to test this idea during a photo-walk in Lyon, France, August 17, 2023.
The camera lens was equipped with a 36 mm pusk-on FOCA metal shade hood and a FOCA filter adapted to the 32mm diameter of the Schneider-Kreuznach Retina lens. Almost all views (excepted the specified bellow) were done with a AUV filter.
The film was exposed at f/16, as far as I could, and 400 ISO privileging the shadows or darker zones using a Minolta Autometer III equipped with a 10° finder for selective measuring. When necessary (bellow 3m) the distance was evaluated using a small LASER range finder and I reported the value to the camera distance scale.

After completion, the film was revealed using Adox Adonal (Agfa Rodinal) developper at dilution 1+25 and 20°C for 10min30. 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. The RAW files obtained were processed without intermediate files in LR and edited to the final jpeg pictures.
All views (plus some smartphone documentary pictures) of the film are presented in the dedicated album either in the printed framed versions and unframed full-size jpeg.
About the camera :
I found this Kodak Retina IIa camera from my local photography store on August 5, 2023, Lyon, France.
Kodak Retina IIa camera's were manufactured in Stuttgart, Germany, in the years 1951 to 1954. The IIa is equipped with a Scheinder-Kreuznach lens 1:2 f=50mm and at Synchro-Compur shutter operating from 1s to 1/500s. The IIA version of Retina camera's has also a range finder coupled to the focusing helicoid.
The principle of Retina camera's are the folding lens with a bellow to give a very compact body when folded. The Kodak Retina IIa is a beautiful piece of manufacture, typical of best photographic German industry.
After detailing and blank mechanical tests, I did a test film with a Fomapan 200 at Parc de la Tête d'Or. I used a 36mm ush-on Foca DYMA filter, adapter to the 32mm lens of the Retina. I exposed the film for 64 Iso to compensate the DYMA filter absorption. Snce the range finder was not correctly calibrated, I focused the lens trusting the distance scale and used a LASER meter to evaluate the object distance.
The expositions were flawless on the field but I had a blockage during the film rewind that I could not manage by pushing again the rewind small button of the bottom of the camera. The best solution would have been to open the camera in the dark to recover the film, but I tried to re-advance the film and the film broke. I just succeeded to save the 15 first views of the test. Some are presented here in the dedicated album.
If the exposures were OK, I noticed a problem in the focusing with a clear out-of-plane off-centering likely due to a dirty helicoid of old dried grease in the ramp. I hope to find a good technician to re-calibrate the range-finder and clean the focusing ramp.

A few unexpected problems with engine recommissioning delayed our launch
for the season by a couple of weeks. Frustrating - not because time was
critical, but the continuing exceptionally fine weather was giving
summer temperatures in early April. At last all was put together again
with no bits left over, and off we set from Dumbarton. The first short
leg was down to Millport, then on to Campbeltown the next day. There we
sat out a day of strong winds when the Sanda ferry was unable to reach
the island.
