New camera lens

The little Canonet is a fun camera. I briefly had the f/1.9 version, but I sold it off as I prefer aperture priority to shutter priority. Replaced it with an Olympus 35SP, that I then sold off when I realized I didn't really care about having a meter or an automated exposure mode. That said, the whole class of reasonably affordable small semi-automated cameras with great, fast prime lenses is something that really doesn't exist anymore, which is a shame.

Modern hearing aid batteries work fine. They don't last, but they are cheap and easily available. At least the battery compartment is accessible with film loaded on the Canonet (unlike my Rollei 35, but then I really don't use the meter anyway...still a fairly stupid design, though).

Those zinc/air batteries are not very reliable so I went with something like this in my Ricoh TLS. 

For something not much larger than a Canonet, you can have a Pentax MX and their pancake 40mm, although the Pentax M 40 f2.8 lens isn't as optically good nor as fast as some of the lenses that were fit to Caonet's.  Overall I think the MX is a much more capable camera.

Thank you. I saw those adaptors online. So that's the hot replacement for my 625PX? Know anyone in the States who stocks it? (And I'm waiting to hear back from my local shop right now.)
