HELP!!!! What the heck are these?

[larrywseale]

I picked up a Mamiya M645 at an auction and when I got the box home and unpacked it, there was a plastic case with the three metal gizmo's (descriptive term in it:

The gizmo's are about 1 3/8" in diameter and there is a bottom lip on each, about 1/8", that looks like it's meant to be pressed into a tube of sort sort. The only markings are what's show in the scan and a "Made In Japan" on the plastic case.

Thanks -larry-

Attachments for a soft focus lens? Just a guess.

Inserts for soft focus...

If they're for a Sekor 150 mm (either RB67 or RZ67 version), they might be of use to someone, they often get lost. By using the different inserts in the lens you can achieve different levels of soft focus.

Often called diffusion discs.

They are the soft focus discs that come with the 150mm SF RB67 lens. I'm not sure if the 645 mamiya has a SF lens, but see if you do in your kit?

If you have no need for em, I'd like to buy them form you? I have the lens but missing the discs.

Thanks to everyone who replied. It was a mistake that I ended up with them as they certainly don't go with the M645 I purchased but at least I learned something new.

Thanks again.
