Wow

My camera is 6x12

This looks very advanced. With video camera and video monitor as electronic viewfinder. What is your focusing mechanism? Is it couples with the electronic viewfinder, or zone focusing?

Look forward to your photos!

Nice! Used the same body for my mod:

Here's a modification of my previous 6x7 coupled RF. Found a Xenotar 80mm f2.8 (same as Rolleiflex AFAIK) in a barrel mount and it transferred perfectly into a no. 1 shutter. Had a new body printed (MJF process) and modified the Canon 7 cam follower to match the lens. Not a fan of the press shutter... there is a long travel and a sudden detent that tends to induce camera shake.

Not to denigrate anything, since I too like the joy of tinkering -- I respect your work too -- but that aside what's the point? A dedicated hand-held 6x7 rangefinder that looks like an imitation Mamiya Press and seems to be less capable.

Its hard to tell much from your sample photos. How well does the 80/2.8 Xenotar do in the corners? I ask because Schneider claims that it covers 91 mm -- almost exactly 6x7's diagonal -- and because my little Xenotar, unlike the 80/2.8 Planar, isn't really usable on 2x3 (6x9 in metric).

I have this lens on a Crown Graphic using 6x7 roll film backs. And it does cover 6x7 cleanly to the corners. Then it falls off remarkably fast!! I can do a small forward tilt for greater depth of focus, very small, and that's about it. Almost no effective rise, etc.

Well the point aside from tinkering is to take pictures. Sure the Press is more capable but at the cost of extra weight and bulk. I haven't tested the lens much yet but as you say Schneider literature claims 91mm circle at f/2.8 (and 98mm at f/22) so it should be fine for 6x7 and smaller. I don't have a 6x9 back.

I have a similar Xenotar 80/2.8 barrel lens rescued from a 70mm aero camera. Due to its quite short flange to film distance, I cannot adapt it to my Pentax 6x7 or any other medium format SLR.

Thus currently I use it with adapter on Fujifilm GFX-50R digital medium format camera. But it would be nicer to utilize its entire 6x7 coverage on film, if I can figure out how to focus precisely in a customized solution.

The Xenotar is a lovely performer so far. I'm sure you've noticed it on the GFX. The RF coupling came out quite accurate with nicely defined eyelashes on a portrait at ~1m.

For sighting, a cheap 4.3-inch FPV monitor with a resolution of 480x272 is used, by attaching a camera with a viewing angle of 110 degrees of the PAL or NTSC system to it

Here's something a little different. Had a leftover GS645W body after I used its lens on a 35mm panoramic rangefinder. After five tries I finally found a 35mm format lens that fit and was correctly located for infinity focus (after slightly tweaking the helicoid scale). A 4.8cm f2.8 Mamiya triplet lens from the 35S. Lo-Fi is fun!

Not to mention no unrepairable electronics to fail without warning... As I've asked before, who needs an Xpan? A humble Century Graphic can do more, and on 120 film with lenses from 35 mm to around 200 mm (non-tele) and 250 mm (tele) that cover 2.25" x 3.25".

Here is a WIP. Canon 7 with 63mm wide frame, new pressure plate and "corrected" film advance. Front plate machined for a slow-pitched helicoid (Hoya 28mm) with a Fuji 45mm f5.6 (from the GS645W) mounted on a #00 shutter from a Kodak Retina 013. Next I'll try to couple the rangefinder.

You could not preserve the fuji shutter?

The Fuji shutter was preserved on the 645W body. I didn't want to sever the cables for the coupled meter. Plus it doesn't have a proper T or B setting. Glad I kept it because I now have a Holga type camera with a coupled meter, nice finder and lever advance & cocking

If Fuji makes a simple panoramic camera with a lead shutter I will pay a lot of money for it. Don’t need anything fancy.

That is GENIUS!!!!! So cool, thanks for sharing!!!

Thanks @dirkfletcher.

Here is another panoramic build. Nimslo body with lens plate removed and baffles machined out (~24x72mm frame). Bottom plate replaced to accommodate a Zorki-6 RF unit, coupled to a Schneider 47mm f5.6 lens. It uses the same helicoid mount than another pano build so I can swap the lens between the bodies. Toothpick required to press the rewind clutch .
