Talk about Photox 6789 cameras

[silbersalz]

Hello folks,

This is my first post here in the forum.
I bought a Photox 6789 in Japan yesterday and it's on its way to me. It doesn't come with a lens board, but I've read that simple pieces of sheet metal 1mm thick will work. Is that correct?

Also, is it possible to use lenses in Copal #1 shutters? I have a 105mm Nikkor that sits in a Wista-Press shutter that is size #1. Until now I only found pictures showing Photox cameras with lenses in Copal #0 shutters. I really want to use the Nikkor but don't know if it will fit.

Thanks for your help.

P.s.: There seem to be different versions, I bought the obe with front tilt/swing and rise. No more movements.

I’ve never heard of the Photox, but I suspect a Copal #1 will work, looking at pictures. You may need to orient the shutter on the lens board carefully so none of the parts of the shutter that stick out interfere camera controls. I have a Linhof baby Technika that came with a Xenotar 100mm f2.8, and it fits but barely, and it needs to be turned so the certain parts don’t interfere.

I’m surprised a Nikkor 105mm is in a #1 shutter. Which 105 is it? I have a 105mm M which is in a #0, and the 105mm W came in a #0 as well.

I'm really looking forward to getting the camera. I've read that it's supposed to be made by Nagaoka.

It's a Nikkor-Q 3.5/105mm lens with a Wista-Press shutter. I wanted a lens with a self-cocking shutter, and I really like this Nikkor. The lens elements are tiny compared to the size of the shutter.

I'm almost positive that Copal #1 shutters will fit. Does anyone know the diameter of the hole in the front standard of the Photox? That size is my main concern. I'll also use shims to increase the distance between the shutter and the lens board by about 1 mm. That should help with the Copal #1 shutters' larger size.

probably a good fallback plan. I think the camera you got is pretty uncommon but photrio user @B.S.Kumar has sold a number of other 6x9 Japanese wood cameras, so he may be familiar with what you have. The Nikkor-Q are older lenses, but I suspect my -M is the same optical design as your -Q. If so the rear element won't cause any issue. The big difference is the 35mm lensboard hole for #0 and the 42mm hole for #1. Looking at one on eBay ( https://www.ebay.com/itm/146267187240 ) there is clearly space on the lens board for 7 more mm, and the hole on the front standard is much larger so I doubt the 42mm hole will cause an issue.
