then again I want an Aero-Ektar/Wista 4x5 RF and Littman Single 45 so maybe I am just crazy.
You probably want an aero ektar and graflex combo since it has the focal plane shutter you need to make it work. I have two Alpenhause cameras which are polaroid 110b conversions like the Littman and they are great fun to shoot. I use them all the time now. The really sad thing is the loss of the 4x5 pack film, but for now we can still buy 4x5 sheet film.
I saw that lomography 6=12 and was quite happily surprised. Looks like something useful and fun and also very inexpensive as well. I might pick one up myself.
