Eypiece grooves & threads

[cooltouch]

I just read at another thread that Canon and Olympus grooves fit each other.

Pentax viewfinders will also fit the Canon accessories, but they are rounded rectangles, so the fit is approximate.

All Canon F1s ( Old F1, F1n and New F1) use the same metal eyepiece rings, rubber coverings, and eyesight correction lenses.

Yep, and they fit nothing else -- that I know of, at least.

Off the top of my head, Miranda and until T4 Konica, I don't recall if the Nikon, F, 2, and 3 used the same thread mount.

Does anyone know if a Nikon diopter (19 or 22 mm) fits on a Konica T3N?

I found this via Google using “Konica T3N eyepiece thread”. It implies that the Konica T3N has 18 mm diameter eyepiece thread. It doesn’t mention the thread pitch.

Yes, I found that article as well and I got me confused as I vaguely remembered to have read somewhere that Konica used a 19mm diameter. Hence the question. It looks like I have mixed up Konica with another brand or camera.

Nikon 19mm fits Fuji 'Texas Leica', GW690, GW670, etc. So great for eyecups and attaching a Nikon DR-3 viewfinder when doing lower shots on a tripod.

It has been a few years since i looked, but i could never find any of those, with the rubber cover.
I would like to have a couple of spares.

Years ago I couldn't find a diopter for a Konica Autoreflex. I bought a Nikon diopter and had my repairman remove the glass and install it in a Konica eyepiece.

So would we all Chip, but it's probably more than thirty years since they were manufactured. The only thought that occurs to me is that Ffords in Scotland a few years ago had bought a warehouse full of new unused Canon FD camera, lenses, and accessories from a men in Glasgow who had owned them for years who was retiring, you could ask Ffords if they have any.
P.S The metal eyepiece ring and the rubber outer ring were always sold separately.
