The Leaf backs can be ordered in almost any camera mount ... the CFV fits one. Economy of scale, you do the math.
Sadly not in Rolleiflex mount (the Leaf backs), at least not the newer, more interesting backs. I would be quite interested in getting a back for the 6008 system.
You make some good points about the V system, and I am finally, finally ready to agree with you about the desirability of the V system as a basis for digital explorations. Some will want it, and I regret that Hasselblad was never able to make a nice, large square sensor back for fans, but I guess that is just the economics of a company getting out of one system nearly too late, and investing in a new one. The CFV16 will always be a classic, I guess, just too bad the sensor is so small. A 48x48mm sensor would have been great, even with only 30-40MP.
I did for a while foster the notion that the 200-series could have been a good base for an alternative system, but having bought one, I was surprised how quirky it was, with metering only usable with the loupe up in the waist-level finder, a choice between ISO from a film back OR communication with a digital back (and a permanent choice at that), and that weird menu system, and difficult-to-read LCD. Throw in the off-centre strap lugs, and at some point it just dawned on me that this is not a modern 500C/M, but a quirky camera made quirkier by the addition of some features which didn't fit all that well. I have made the decision to sell it, as good as it is in its sweet spot.
I have now bought a 6008i instead, and although it is a bit bulky and not as elegant, it is far more modern with a very intuitive control scheme and modern electronics. Too bad the company which brought it out had terrible marketing and international distributors, and worse financials. I hope that DHW can stay healthy and maybe nurse the Hy6 back to full viability. Hope, but don't expect. That is the system I wanted the V to grow into, but Rollei never had the marketing power or success of Hasselblad, so I guess there was no way from here to there, really.
I like the Contax 645 rather a lot and just can't seem to part with mine, but other than that, I am not fond of any other 645 camera. The Mamiya just never appealed to me personally, although it has grown into a good system, and having had a good try at an H4D-40 recently, I had to accept that this camera is also not for me, although I can see that it is a very flexible and competent system, very strong for professional use. I don't love it though, it feels like a tool to me, but not a favorite tool, just a competent tool which does the job, yet doesn't earn my love. This is my personal reaction to it though, and is not really relevant to anyone else.
That leaves me with very little choice. Hy6/AFi with Leaf back is one option, S2 is another, although that is just too much money for what is after all just a hobby for me. I could swing around ten grand, but not twenty or thirty, not with a good conscience. If I could just sell a few large photos, then maybe I could justify it, but that isn't the case, I am just not set up that way for now.
Anyway, I am always watching this space with curiousity, it does have some of the characteristics of a soap opera
