I'm with 1:1 even though to my everlasting shame I have a couple of cameras I bought to use and then decided not have made usable.
Retina 1b (small b) and Retina IB (large B). They're pretty things, also pretty heavy, but that's not why I bought them.
I have a couple of bizarre-looking cine cameras that I bought to use and did use, shot parts of a couple of epics (66 min, 45 min) with them. Again, I didn't buy 'em for looks or cool, I bought 'em for what they could do. Oh. 4008 ZM-II, 5008S-MS.
