I just wrote Chamonix about the availability of the Sabre. Anyone aware of anyone else modifying standard pack film Polaroids for 4x5? I'd like to consider all options. I'm not keen on the 110 mod. As beautiful as the 110 mods are, I'm interested in the lightweight packfilm conversions....
The Sabre looks like a great option as 665 becomes increasingly hard to find, more and more expensive, and of unreliable quality....
