Most folks here are Alpa, Arca and Cambo users - all good equipment. So from another perspective, the Techno. Its a more traditional view camera setup, with a rigid back allowing only rise/fall, with side shifting either from the front standard or with a stitching back. Some might not care for that, but its main benefit is use of simple view camera lenses on a board, with all your movements (tilt and swing too) without needing any special mount. For me, that flexibility was attractive, especially since I didn't know what lenses I would prefer over time. It also allows for easy (cheap) trying of different lenses.
The major use change in a tech camera for me was first, the dedication to shooting from tripod only. That was easy enough, but harder was setup in the field, especially when using a stitching back. I like to walk and shoot, so a fixed setup point at one place isn't ideal - and its not like you want to walking with the stitching back on. For this , the pancake cameras are easier to use.
One way to deal with this is to directly attach the back to the camera, and find some way to focus. Surprisingly, this works - you set the lens stops to infinity, and use hyper focal (f11) for landscape shots. You can chimp for composition (Usually 3-5 shots gets the focus if other than infinity), and sling the camera over your back for short walking. I'm not a fan of taking backs on and off - too much dirt and risk.
TJV is exploring a CMOS back on the Techno; others have used ND filters and live view. One could also imagine that a faster back (say a Credo) on the camera might make chimping more workable.
Use of a stitching back allows GG composition and focus, which is good fun, and focusing isn't that hard. Torger's analysis on focus is pretty much spot on, but its pretty easy with the 12X loupe. Of course, I'm not doing much critical shooting close up (say 8') where the DOF is really small - and for that one would need to check the files anyway. If you really want to shoot wide open at close distances, then there might be better ways to go. But use of the GG allows you to consider what stitching might look like before you shoot.
Linhof makes two stitching backs, a really long one (essentially 3 parts wide), where the GG is always covered, even when the back is shifted on the camera. While ideal, its heavy and makes for a great wind sail. They also have a shorter one (2 parts wide), which works fine too. My Leaf AFI back mounts won't work with their shorter back, so two alternatives:
Kapture Group makes a 3-way back that will take almost any mount (front and back). Nicely made, easy to use, and all sorts of formats can be done with it. Issues: it won't focus the 35mm lens (it sits too far back), and more importantly, the digital back mount is held in by a sturdy but spring-loaded clip which is fine for standing still, but not foolproof if moving about.
Silvestri make a stitching back with a lock to hold the back in place, and it also focuses the 35mm (on a recessed lens board). But its not as flexible as the KG, nor as easy to use. The KG ground glass (probably Maxwell) is better, you can pretty much focus in daytime almost without cover.
