I couldn’t help it:
That’s a 350RMB Jupiter 8, an 85mm portrait lens, made in the Former Soviet Union (FSU), in 1974. Successfully adapted to my Canon 350D.
According to research, the price I get the lens for is a fair bargain. The question is, based on the looks of the lens itself, it doesn’t seem like it is of the M42 mount, rather, its the M39 (READ: mounts, easily put, are how you’d determine if a lens fits to a certain camera; the M42 is my target, since I already have some of these; aka Pentax-mounts).
I was also looking for a Takumar 50mm ‘normal’ lens. This took me in: f/1.4 (READ: the widest opening of the camera is at 1.4, which is wider than some 50mm FSU models). Found one, though the optics was already yellow-ing. Good thing I did my research, since this happens to be a normal occurence to some of these lenses that were made at a specific period.
Sample photos? The Jupiter 9 is primarily a ‘portrait lens‘ (at 85mm; short telephoto), and unfortunately, I don’t have models to shoot. Soon, I guess.
