First test roll of film
The Kuribayashi Petri 7s is a battery less, coupled-rangefinder, leaf-shuttered 35mm camera that was introduced in 1963 and was sold until the early 1970's. Petri called their rangefinder focusing system the "Green-O-Matic." The view finder is tinged green with the focusing area is yellow. This makes focusing easy and quick; it is bright and clear on this camera. The match-
needle system, which is visible inside the viewfinder and on the top plate, is a match needle for under / over exposure. The solar-powered selenium cells circle the lens like an Olympus Trip 35, this automatically compensates for any filters you use. The camera is quite chunky compared to something like the Trip 35, but it feels very solid. The film wind-on has a very positive click feel and noise. The mechanical timer still functions as it should do on this camera.
Now I've put a roll of Agfa Vista Plus 200 from Poundland through it, I was pleased to find that all 24 photos had turned out OK. The metering is not far out. It seems to have a tendency to overexpose, but this is probably down to me being a bit rusty on manual exposure. I can honestly say, I've not used a manual exposure camera since my introduction to photography in the 1970's using a Zenit EM. Unfortunately the high street "photodisc" scans from the film do not really do it justice; the folder says Hi-res, but 2-meagpixel is all they are! Asda may be cheap at £3 for developing and a CD, but I think I would have been better with 6" x 4" prints and scanning myself at 400dpi.
The Petri has all the manual controls you would expect for a rangefinder in this class. The main two negatives I have found are; no hot-shoe and the film speed setting lever on the lens is easily knocked to another setting as it sticks out on the lens. But I'm pleased to say my £8.20
buy off eBay (including postage) has turned out to be a good usable camera.
