First roll with my new (to me) 58mm lens for my Koni-Omega. This is a scan from a machine print. I think I'll have some fun with this lens, especially when I can get back into the darkroom (when our painting is done!).
It is a Koni-Omega M - it yields a nice 6x7 negative on either 120 or 220 film (depending on the back) loaded in a large but easily handled rangefinder. If you hung around wedding photographers in the late 1960s through the early 1980s, you would likely have seen a few of these cameras (or others in the same series) in use. If you google "Koni-Omega Overview Camera Models" your search will yield a site with lots of info.
