just got the Actus DB version today and am in the process of mounting lenses, etc, and will follow up with pictures later.
the DB version differs a bit from the regular by adding a (removeable) riser beneath the front standard.
Mine came set up for the hasselblad V mount back. For this Cambo provides a camera mount plate which can be clipped in to the camera in portrait or landscape orientation, leaving the back attached to the plate. (two flip levers on the camera are the releases) works great.
a few details so far:
focus action has a quick slide and a fine focus, fine enough to set focus with a 28mm lens, using the mag function on the back. the lenses are mounted sans helicoid, and the 28 moves closest to the sensor at inf focus, yet still clears adequately, though i have still to test with tilts. there is a settable stop on the monorail, so you can position it to avoid collisions of rear element and sensor when the widest lens is at infinity
pair of levels supplied on camera
live view is essential, so CMOS is best.
all the movements are smooth and have click stops at zero, however:
back standard: rise and fall are geared, but no scale, has detents every 5mm? of so. shifts also have detents and a scale but are push, no gears. both have locks. i think i can add a little scale
front standard: tilt is goniometric (horizontal rotation axis near lens centerline), +/-5 degrees with scale, geared with detent at 0, and has no lock. same for swing, vertical rotation axis on lens centerline
bellows attaches with rare earth magnets, quite slick
bottom monorail has arca style grooves, fits right into my cube, and can slide toward/away to image, so setting nodal points for panos is easy
so far i am trying out the rodie 32 and 28 lenses, eventually will keep the 32 and will get a 60. (got the like new 28 in a trade (with cambo WRS mount), expecting to try it out, but thinking it will be too wide for me, even with the crop factor)
hooking up the CFV-50c is direct: sync cable from shutter to back, set back to flash sync; with live view enabled, you want the max aperture for better focus, so ND filters might help in bright light, but seemed to work fine. the rodie lenses are not as huge as i was expecting, and they are beauties
info will keep coming as i get more time
