Petri Color 35 D & Foma 100 – A twin test

By Roger

When I see a camera going cheaply in a charity shop, I tell myself that if it turns out to be good it will turn out to have been a good buy but if it doesn’t, then I will have made a donation to a good cause. This just happened when I came across an interesting camera I had never seen before – a Petri Color 35 D. It seemed potentially too good a bargain to be missed. There was a note saying that the shutter had been tested but the meter had not. Inside the case was a receipt for a repair, in 1987, saying that the viewfinder glass had been replaced but there was something that could not be fixed because the necessary part was no longer available. I decided that the price was well within what I would be happy to donate to the charity, so bought it.

Naturally, I looked it up on the web, only to find Hamish has reviewed a very similar model (very similar, except mine has a fastest shutter speed of 1/300 instead of 1/250). I decided the battery was dead, but as the manual says clearly that the battery has to be 1.3 volts and my only spare was an SR44, I removed the battery and decided to test it immediately with a roll of Fomapan 100, a film that I had never tried. (A significant issue is that the battery can be replaced only when there is no film in the camera.)

The test site was Blanchland, a village built on the site of a former abbey, presumably with stone taken from the abbey when it was demolished, though with a few of the abbey’s buildings still in use. It was a dull day, with intermittent drizzle, so fairly low contrast. Exposure was set using an OM4Ti, though it hardly changed at all. The village is spoiled by parked cars but it is easy to see why it is in demand as a film set.

Everything Hamish said about the camera is correct (not that I would expect anything else) though like at least one other person on the forum, I ended up more positive about it. It is a camera that pushes you towards treating it as shutter priority, though as there is such a limited choice of shutter speeds, that hardly seems an issue. What I like most is the viewfinder display, showing both focus distance and exposure extremely clearly. The main frustration is having to turn the focus wheel to extend the lens, especially given that there is a bit of play in the mechanism (maybe that is what the repairer could not fix). There is also the need to remember to delay winding on until you are ready to take the picture, because winding on turns on the meter (if there is a battery installed). But the camera is small and I enjoyed using it. On getting home I installed a zinc-air battery and the meter seemed to tally with what a Weston meter said, which was a bonus.

My reactions to the Fomapan are mixed. Not wanting to waste time or money on something that might not work at all, I cut off half the film and developed in Rodinal 1:50. Given the dull light and drizzle, I am impressed with the contrast and the tones, though the grain is a bit obstrusive for my taste, especially in plain areas. But perhaps that is the result of pixel-peeping 42 megapixel scans done with a Sony A7R3. It makes me look forward to seeing how similar shots taken on the same day with the OM4Ti on Pan F look. It is possible that results would be better with a tripod, as there could be a trace of camera shake, though the grain makes it hard to tell.

I enjoyed using the camera and intend to use it again, next time using its own meter, though my rational self says it would be much better to use my OM4Ti, which is easier to focus, has better metering, and allows me to use a focal length other than 40mm, or even a rangefinder with interchangeable lenses (such as a Leica IIIf, despite its inferior viewfinder).

Fomapan 100 is a film I use regularly and - as you say - it is a bit grsiny for 100asa. The other issue to be aware of if you shoot at night is halation around lights. But for an inexpensive film pretty decent i think.
The camera perfirmed well so a good buy, and some excellent images from a photogenic setting.

Great set of shots Roger! My only Fomapan experience is with 4 x 5 sheets.

I think those are wonderful shots, both aesthetically and technically! (Admittedly I wouldn't have thought of using my OM SLR as a meter.) I think your shots and those of Kohtli (https://www.35mmc.com/20/12/2024/petri-color-35-a-love-letter-to-a-favourite-camera/) make a very good case for the quality of the lens, which people usually complain is inferior to that of the Rollei 35 (Tessar or Sonnar).

Stephen Gandy praises the Color 35 as a design masterpiece, saying it's what the Rollei 35 should have been: https://cameraquest.com/petri35.htm . I have a Color 35 (fastest speed 1/250) in need of repair, which I haven't tried yet, though I just noticed that Mike Ekman has included the repair manual in his thorough article on the camera: https://mikeeckman.com/2022/03/petri-color-35-1968/ . When I get a little time maybe I'll have to try to fix mine, though its problems, including a non-retracting lens and a non-clicking shutter, will clearly require some serious disassembly.

Thank you for these comments. The village clearly has potential, especially in more interesting light and with more time to explore.

I come across Petri 35 cameras quite often on my monthly visit to a Japanese eWaste sorters in Cambodia. Another story for another time. Sadly they are usually badly affected by container moisture.

I use forma as my everyday film stock - working in Cambodia 100ASA is a fast film. But I also use fomapan 400 at times when home in France (Brexit refugee) in the winter. Both are nominal speed films so can almost be used interchangeably. I develop 100ASA pushed to 400 in D76 with times for foma 400 +10%.

I tend to like the grain. Its a reason I use a lot of it. But yes in lower contrast shots it can be obtrusive.

Anyway - thanks for sharing some lovely images.

Thanks for the comments. I guess it is sad to see cameras being scrapped like that. I tend to use box speed and, most of the time, recommended development times, not having the patience to test different combinations of ISO setting and development time.

Nicely shot Roger! I actually like the way your photos came out, I think the subjects matched Foma's feel very well, but I understand how harsh the grain structure of Foma film can be. Pan F is the complete opposite, it is beautifully detailed and rich in tones, so I think you might like that one instead.

From all of these reviews, I get the impression that Petri cameras are quirky but competent. At the very least your Color 35D turned out capable in your hands. It's pretty nice to see how this much smaller, lesser known brand was able to put out a rather impressive compact design, and the lens certainly deliver on quality. Enjoy your camera and looking forward to more shots from you!

Thanks for the comments and for confirming my view of what to expect with Pan F+. I say that because the roll that was in the OM4 when I was taking these shots on the Petri turned out very thin and contrasty, without the range of tones i hoped for Although I did retrieve them on the computer, the results were not what I had hoped for.
