Jobo – manuals etc.
Lens – Schneider 4×5 M-Componon 80/4
I stumbled upon this „Lupenobjektiv“.
It has a reduced focal distance and is usually used with a macro tubus.
Schneider : Lens for high resolution, up to large format macrophotography; used with Copal 0 shutter and special macro tube for Linhof Technika. Also ideally for 35mm on bellows.
| Focal Lenght: | 80 |
| Aperture: | 4.0 |
| ApertureRange: | 1/2/4/8/16/32 |
| Magnification: | 1:1…7:1 |

| Mount: | M29.5×0.5 |
Another user tells me it covers 8×10, I have still to try this.
Film – Perutz 17
The German firm of Otto Perutz was established in 1870. It was the first to produce a roll film for the Leitz camera.
In 1880 Otto Perutz started the Perutz-Photowerke in Munich, Germany.
They first made dry film plates there and later made many innovations in early film photography.
The Perutz 17 film was produced in 1956, eight years before Perutz was taken over by Agfa in 1964 and in the year of my birth.
I got the Perutz 17 „tropical“, 40 ASA, expired 1966.
The „Tali“ meant in daylight loadable film, these had no cassettes.
Sadly I got no usable negs out of it.
Film – Orwo NP22 (exp. 1998)
I scanned the flyers that came with the 120 film and found the original R09 dev receipt:
I exposed the fim in an old Agfa Isolette a bit longer, using the sunny sixteen + one stop.
In R09 development 1:40 I used 20 Min at 20 Celsius, every min 3 agitations.
To compensate for non constant agitation you should at 15%, I did 20 min dev to give the film one more stop due to the old age.
Results were fine.
Film – Delta 3200
Dev times
Real Sensibility is about 1250 ISO, be careful with Rodinal (grain)

2019/10 when in spain…
While on a trip in spain I had my RSS 6×6 pinhole with me, along with Agfa ortho 25, expired 1992, later dev. in Rodinal 1:100 semistand 1 hour, 20 Celsius.
Camera – Cameradactyl
Finally a free afternoon. I went out with the (black) Cameradactyl 4×5 to try a few shots with the cheaply aquired, cleaned and mounted 127 lens.
Of course as soon as I arrived with my bicycle the weather went to light rain.
The tripod mount I glued in is not stable (looking for an idea to get it right) and while composing the camera was rather wobbly on the tripod.
Fuji X-ray film (Fuji AD-M 18×24 100 Bl. mammography film, one side emulsion), Rodinal 1:100, 20 Celsius, about 10min under red light with visual control.
The pic shows part of the eremitage, a long forgotten place where some monks once lived in solitude near the Nahe valley, Bad Kreuznach.
RSS 6×17 Pinhole Camera
A very nice ultrawide pinhole camera from James Guerin at aupremierplan.
Here is his description the loading of this camera:
Curved film plane?
The film plane is curved to ensure even exposure across the negative, not possible with a flat film plane with such an extreme wide angle view (141° angle view of equates to a focal length of 6.4mm in 35mm terms). T
A side-effect of the curved film plane is that it results in a curved horizon in your photos unless the photo is taken with the camera level. This is why a precise bubble level features on the top plate of the camera.
Camera features
- CNC machined body
- Curved film plane with a radius of 70mm (focal length).
- Large 6x17cm (57x170mm) negative giving 4 shots per roll of film (120 roll film).
- Angle of view: 141 degrees horizontal, 44 degrees vertical.
- Laser drilled 300 micron (0.3mm) pinholes (f/233). Pinhole material thickness = 50 microns (.002″).
- Magnetic shutter
- Dual pinhole allows horizon to be placed on upper or lower third (camera level)
- Accurate aiming lines for composition.
- Precise bubble level.
- Standard 1/4-20 tripod mount socket
- Rubber feet
- Film spool tensioner at take up spool
Film – Agfa Ortho 25
I got some of this film in 120 format.
Dev in D96 monobath worked
Dev in Rodinal 1:100 semistand 1 hour, 20 Celsius worked with heavy fog
Agfa Ortho 25, Rodinal 1:100 semistand 1 h, 20 Celsius, pinhole
In this pic the fog actually compensated the highlights
