Body from 1961, lens from 1957, so it’s of the same vintage as me.
This was the end of the line for screw mount rangefinders, the Canon 7. Rugged and beautiful, it was equipped with a selenium coupled meter (still works), a long base rangefinder, an accurate and very rugged shutter, and in my case, the wonderful Canon f1.2 50mm lens, fast and sharp. I would still use this lens even if I was fortunate enough to have a f0.95 dream lens. My secondhand shop rummaging has turned up a Canon 135mm f4 lens (a Sonnar design), a 50mm Canon Serenar f1.9 collapsible lens from about 1949, and I also have a modern Voigtlander Snapshot Skopar 25mm f4 zone-focus lens when wide is needed. All of these lenses can fit the Digital Pen through two adapters.
The viewfinder is clean and uncluttered. A dial on the top selects 35, 50, 85/100 and 135mm framelines. It is much better than the cluttered finder in the Canon P, a screw mount camera that is sought after by just about everybody else. Been there, done that, and didn’t like it at all.
I have found the correct Canon ventilated hood, and its original design ever-ready case too. Oh, and a modern unbreakable strap. Just made for portraits in available light.
