Bronica ETR to PK?

Hi. Thank you all for your input.
Sorry for not having come here earlier, but I was counting on getting an email notification and must have missed it.
I had seen some reference to something like the MultiMount some time ago, but the website wasn't anywhere as professional so I kind of moved on (possibly a mistake). It does look interesting, but there's things I'm not sure of:
- is the change of mount reversible without too much hassle?
- do real PK lenses behave as well in the MM, the WR issue aside?

After all, we'd like to use the Bronica lenses for fun (and because they're primes), not because we can't get PK ones.

One (just one, nothing more) of the reasons we got a K-30 instead of one of the smaller models was the weather sealing, tho as prophesied we actually have no WR lenses. My impression was that at least part of the body, if not the hole behind the lens, would be more protected against accidental sprinkling or moisture. Or maybe it's just marketing hype, but it does sound comfy.

I'll concur that calling the version-for-WR-bodies the WR-version is a bit misleading, unless you read carefully you'd think it preserves the WR character of the body. I don't understand whether they could add an O-ring to the MM so as to keep it WR and chose not to, or whether that's technically challenging or impossible.

The 1mm ring approach nanual linked to seems interesting and even simple. I'm not the handicrafty kind of guy, unfortunately, but I'll give it a more thorough look.

Hi. My apologies if this isn't the correct forum, please move the thread if so.

In the '90s I enjoyed shooting with a Z-70. In the '00s it started collecting a bit of dust, and only recently did we get back to film, but at first in the form of 120, specifically Zenza Bronica ETRSi. I then got to properly scan my old 135 negatives and was surprised at the quality, which made me decide to give the Pentax some more use. And, what's more, get a K-30, so we could move the lenses around. So far, just perfect. The only thing we're missing is a UWA, but one will appear eventually (the widest we have is the FAJ 18-35).

I got thinking it would be nice if we could sometimes use the Bronica lenses (40, 50, 75, 150) on the Pentaxes. Not that we need to, or expect awesome results, but I can't believe it wouldn't be fun. I know there are adapters from ETR to Canon and Nikon, but I haven't been able to find anything for PK. There seem to be SQ adapters, but not ETR. Not even ETR to something plus something to PK (maybe Nikon, but Nikon to PK is lossy, iiiuc). Given that, does anyone have any ideas on how it could be done? I know there are some ETRSi users here, maybe one of you has thought of this before?
