Having posted a pic yesterday in the gallery of a camera I had not used ( Zorki 4K ), here is one that I got at a boot sale for about £10 and used on and off throughout the 1990's.
Agfa Record 6x9 cm.
Great for outdoor pop concerts where any camera that looked even faintly serious was not allowed. This folded up and slipped in the pocket so very discrete. The huge negative could stand a lot of cropping to give the equivalent of using a serious telephoto lens. Limitations were shutter speeds, with a max of 1/200 sec, and requirement for a seperate rangefinder to determine focussing distance if under 100ft, and of course a seperate light meter. Nothing built in here.
Also unlike todays digital image storage you could only get 8 frames before needing to change the film.
