65mm
90mm
The flange focal length for the 47mm f/5.6 Super-Angulon XL depends on the shutter it's in, according to Schneider's literature.
Copal 1 = 59.1mm
Compur 1 = 56.9mm
Prontor 01S = 57.0mm
The 65mm f/8 Super-Angulon, for which the fixed-focus Travelwide is designed, has a 70.5mm FFL in its Copal 00 shutter.
You'd need to do some very serious hot-rodding to get the 47SAXL to focus at infinity as the Travelwide body is too long. Nothing's impossible, though.
Before the Travelwide, I was thinking of making a 5x7 P+S. You need a lens, a back, and a box. None of these are particularly hard to get. A 5x7 back costs about $40 on ebay. I can make a box. I have a lens. If you want a camera for the 47mm XL, make it.
Ramiro posts here; check out his camera and what he's done with it: https://www.flickr.com/photos/rabato/13082190464/ He even made his own back, which is certainly more than I would do.
He's used it with several lenses, including a 75mm (that's the one that cuts corners), but I don't know that they're tagged in his series.
Thanks, but I'd rather just watch:

Because the results don't meet my exacting standards of sharpness in the intended plane of best focus. If you can live with having the plane of best focus not exactly where you want it, more power to you.Originally Posted by Corran
Looking at things at 100% on a computer taught me that there's no such thing as depth of field. There's only personal tolerance for out of focus.

Which is what? Are you scanning with a drum scanner? Are you printing to 20x enlargements? Are you examining test charts with a microscope?
According to the commonly cited DOF calculator, even for a circle of confusion corresponding to 6x7, a 47mm lens focused to 10ft. @f/16 will have apparent DOF of 5ft. to infinity. Yes, DOF is rated as "acceptably blurry" but come on, let's be realistic here. Even for 35mm, at f/22 and focused to 12ft. gives "acceptable blurriness" from 6ft. to infinity. Hyperfocal focusing is not a myth.
I'm genuinely curious here. Obviously for some kind of scientific imaging the standards are different, etc. That isn't what's being discussed, unless I've missed something.
None of the above. I examine E6 transparencies with a 12x magnifier.
Fotoman makes a helical lens mount if exact sharpness is desired:

Fotoman also has an optical viewfinder at a reasonable cost if you want "point and shoot"

A solution for the "DIY" builder could be two boxes- and inner and outer- that could be slid back and forth to affect focus. Maybe make the fit a little loose and then put some get around the edges of the inner box to give a little friction to hold it in place but easy to move when wanted.
Isn't the Travelwide designed around the 90 Angulon?
There are two Travelwide versions. The one with the focusing collar is indeed designed around the 90mm Angulon, although many other 90s will work as well according to Ben's posts.
The other version, which replaces the focusing collar assembly with a flat plate, is designed for the 65mm f/8 Super-Angulon. I'm going to try it with a different 65mm lens I have (after enlarging the hole to Copal 0 size), although this will probably take some shims or other minor mods. I suspect setting it up for the hyperfocal distance will produce adequate sharpness for my needs
