I realize this probably doesn't belong here...
because there isn't a medium-format sensor to be seen anywhere, but Hey, it's definitely a "tech cam" and it fits well my present needs / budget, so why not?
The body is a Sony A7R. Surprisingly, for the type of low-light, long-exposure photography that I mostly do*, I find it to be a better performer than the A7RII and A7RIII, so it has been easy to resist upgrading it. I have mounted it to the Mamiya 645 mounting plate that came with the Cambo when I bought it used a few years ago from Steve Hendrix at Capture Integration. (At the time, I intended to use it with my older, Phase One CCD back and Contax 645 lenses, but the lack of live view made this setup too awkward / difficult in use to ever be practical, so I parked it in the back of a closet until I resurrected it for this project in mid-2016.)
To change the A7R orientation from horizontal to vertical, there is a lever that is slid to one side, the mounting plate is removed, rotated 90 degrees, then remounted, and the lever is then slid back to its locked position ... easy-peasy! That said, however, I do plan to revise this to use the rotating mount from a Cambo Actus GFX which is available separately, so the A7R body won't need to be removed from the Cambo to change its orientation, but I haven't gotten around to implementing it yet.
I have also fabricated several lens panels for it, so I can use pretty much any Nikon, Contax, and Pentax-mount lenses with it (although not all of them project sufficiently large image circles to allow for a useful range of rise / fall / shift movements, alas) For the moment, I am happily using several vintage C/Y lenses, which while not the last word in resolution, I nevertheless find to be a welcome alternative to the excessively sterile / clinical lenses -- I'm looking at you, Sigma Art lenses! -- that I had gravitated toward for a time. With a bit of additional work, I should be able to accomodate a Canon EOS lens mount, too, as the 11-24 zoom is potentially very appealilng due to its short focal length range and the generous size of the image circle it projects across that range. (But for a fraction of what the 11-24 costs, I can also buy both the 11mm and 15mm Irix prime lenses in a Nikon mount and they project generously large image circles, too. Decisions, decisions...)
The external monitor is a carryover from my time using a Cambo Actus, because I needed the larger screen to better see the effects of applying tilt and swing movements. Obviously, that isn't an issue with the WDS, but the larger screen does make it much easier to compose and focus photos, especially at night, when reflections from the glossy screen are non-existent, unlike during daylight photography.
I have also rigged a remote battery setup for the A7R because it helps keep the camera slightly cooler in operation (by removing the heat from a discharging battery to outside the body) and I needed to carry one around to power the monitor anyway, so I threw two stones at one bird. A set of four, fully charged 18650 cells will typically last me just under three hours, so one set covers me for most of my outings (although I do carry a second set with me, just in case.)
Oh, and I removed the wooden grip and replaced it with a sturdy one made from .25" aluminum plate, then rotated the Cambo 90 degrees before mounting it on my tripod. This had the effect of swapping the rise / fall movement from the front of the camera to the rear, where it's more useful, because the lens never moves, so I don't need to recompose my images after applying rise or fall movements. Unfortunately, it also had the effect of swapping the shift movement from the rear of the camera to the front, but I don't use this very often, so it's not a huge issue for me. To my surprise, working with the geared movement control knobs located on the front of the WDS body while standing behind it hasn't proved to be a PITA at all ... who knew?!
For my purposes, this camera setup works better overall than my early-vintage Cambo Actus, which, to its credit, is also slightly lighter and more compact. But I've found that it's very difficult to truly zero-out the tilt and swing movements, which I rarely use, especially when I carry the camera mounted on a tripod over my shoulder while walking around on foot, sometimes for several miles. Even though I tightened both movements considerably over how they are set at the factory, I've found they tend to drift over time, presumably from the camera being bounced around on my shoulder while I walk. This is very frustrating, as it's hard to notice small amounts of unintentionally applied tilt or swing movements until after I'm back home again and looking at my photos on the computer, when it's too late to do anything about it / them. (FYI, I have experimented with applying a small amount of fixed tilt to the lens panel of the WDS via shims and this approach seems to work surprisingly well for most photos. I also have an idea for incorporating an adjustable tilt / swing mechanism to the lens panels, but for now, I don't think it's worth the effort.)
So there you go: A traditional tech camera that is built around a 35mm-format sensor and 35mm-format lenses. I doubt that I'm the first person to have ever assembled such a FrankenKamera and I equally doubt that I'll be the last person to do so, because it works so well for certain types of photography.
