Thanks, everyone for the great info and choices. For a variety of reasons, mostly budget related, I will go with the Cambo Ultima 23D. The Sinar option outlined by Chris is very tempting, and equal in saving$, but some other factors fell into place for the Cambo.
This will free up budget for lenses and possibly a coveted digital shutter.
When testing the ArcaSwiss M doing production work or even just standard focus stack work, I found the normal manual shutter to kill a lot of time, and in the case of focus stacking, camera movement because of having to touch the lens to cock the shutter... so am interested in putting some $ there, at least into the SK120 ASPH, as that will most likely be my go-to lens for most production and focus stack work.
Looks like there are a variety of digital shutters on the market, now need to check into them. The Sinar eShutter looks great and is outlined by Chris above which is a big plus for me, but I would like to know more about the competition (SK and Rodenstock have versions too it seems)
Also, is everybody who knows, in agreement that the 40mm Rodenstock HR-W is the best solution with the IQ250 back? (I know there is always disagreement about this stuff, but heard sometimes the IQ250 has a particular need for microlens straight angles...
Pic of demo Arca Swiss Monolith in studio being tested...simply awesome machine I must say, but if I went with it, would have no money for the glass I need. Kindle like spending entire wad on a house and having nothing left to furnish with
In the end, I'd rather have a fully functioning Toyota than a Ferrari without gas or wheels.
