I'm only vaguely interested because of the mount.
If I had a system with the mount I'd be very interested.
I wouldn't buy into a new system because of the lens.
I would be very interested in Petzval cells that could mount into a modern LF style shutter, even a Copal 3 or 3s.
I would also be very interested in something for the RB67 system which I have, which is cheap, and which can easily be hacked into a lensboard if you want to use it on something else.
I might even be interested in a 'blad 500 lens.
Just my two bits. It's not like I'm making the thing. Maybe one day....
