Please, please, please, test focusing accuracy with something like a Leica D5, cheap laser distance finder or, worst case, measuring tape. Transfer the measured distance to the helical mount and don't use the ground glass for focus.
Ideally do it with a number of lenses at different distances/apertures.
This will test what distinguishes this camera from every other on the market.
If it works as advertised, all the Cambos, Sylvestris, Sinars and even the beautiful Alpas are left for dust.
I haven't even bothered figuring out how to use the distance scale since I always compose and focus on the ground glass. I'll give it a whirl, though if I can figure it out : )
The focusing mechanism IS very precise. On the view camera, a 1 millimeter focus adjustment has pronounced effect, where a ten degree rotation on the RM3D's focus ring is rather subtle. Overall I do find the camera more convenient and more rigid. I like the M2 for furniture and tabletop in studio, as well as long lens details of architecture.
For interiors, the view camera doesn't slow me down any more than the DSLR or RM3D. For running around outside grabbing quick, wide angle shots, I'd definitely reach for the RM3D.
Here's the kit I'm planning on outfitting over the next month or so.
Case 1: Arca M2 with 6 lenses and sliding back
Case 2: Nikon D3 with 3 lenses and M Line Adapter Kit, RM3D, Digi Back (batteries and charger)
What's really cool is that the RM3D lenses are mounted on flat recessed plates that are then mounted in tubes. You can get an Arca 110mm lens board to R Bayonet adapter and have all your lenses mountable on either camera. This possibility is, I believe, unique to Arca Swiss and really damn cool.
When the Schneider 28mm Super Digitar is finally released, I'll have the ability to shoot it on the RM3D, or pull it off that and mount it on the M Line 2, then even remove the rear standard, mount the Nikon on the M2 and shoot it that way... 3 fully integrated cameras... Nice!
I think I may very well be dumping my 645 DF and lenses.
