Zenith and other Russian cameras
I have a few Russian cameras in my collection because they are rugged, simple, and some made of solid brass. A few early examples had unreliable shutters, and lens quality varied greatly. But if you are lucky and find a good example with a good lens then they are trusty friends and produce excellent results. I also have its cousin,(a Zorki 4) for 40 years that when new cost me £17 and a spare lens was £5 in 1970. Its lens always produced great shots every time. I use other favourite cameras, including a 1967 Nikon F Photomic, and a Rolleiflex 3.5 with a Planar lens. The results are sometimes very comparable but the mechanics of my Russian cameras are crude in comparison, But give them a try you may be very pleasantly surprised for very little cost. Like many others, I have gone digital with a Nikon D50 and an Exilim pocket camera, but I miss the pleasure of seeing results appear by magic in the dark room.
