These are my 6X6 SLR cameras of choice. I have always two of them on me when I'm out on a photo shoot, one with color film and 120mm Zeiss Biometar lens, and the other with b&w film and a 50mm Zeiss Flektogon lens. I have some other Zeiss lenses for them as well, but those usually stay at home. Here in Germany, the Pentacon Six TL cameras are cheap and easily available, it is no problem to find a good and working copy. Same is true for its lenses. Nobody can distinguish a print made from a negative out of that camera to a print made with a Hasselblad or any other 6x6 SLR. I like the most the Pentacon's simplicity and especially its comparatively low weight and small size compared to other 6x6 SLRs. Important detail: Mr. Woo operates that camera correctly - don't transport the film and let the lever snap back! This will lead to spacing problems with the film.
Pentagon Six may be the most overlooked medium format camera system ever manufactured since the optics are superb and the camera is extremely lightweight.
