Hmm. Not counting broken and useless junk my wife brings home from auctions (sometimes she brings home great stuff, though!):
8x10 B&J Grover monorail view camera
5x7 B&J wooden tailboard view camera in very rough shape
4x5 early Zone VI view camera
Rolleiflex New Standard (March, 1939)
Agfa Isolette 6x6 folder
Minolta 800si 35mm
2x Minolta 7xi 35mm (kinda went a little overboard when cameras I'd always wanted years ago became almost free on Ebay.)
Petri 35mm e.Bn rangefinder with the 45mm f/1.9 lens
Yashica Electro 35 rangefinder
Yashica Big Mini point 'n shoot
I use all of them regularly, except for the 7xi's which have taken a back seat to the 800si. I actually like the 7xi's better but they eat 2CR5 batteries like candy and that's expensive these days. The Rolleiflex has film winding peculiarities which means that film advance is by counting revolutions of the crank handle; amazingly, the antique Selenium photo-cell meter on the Petri rangefinder still works! Not exactly a "low light" solution though! Doesn't register below about EV 5 or so. The Yashica Electro lives underneath the passenger seat in my car and is just quietly, without fuss, a superbly competent camera. The Big Mini rides in my coat or jacket pocket where it constantly nibbles on its battery. The Zone VI 4x5 gets used the most, followed by the 8x10 and then then 800si, the Rolleiflex, the Isolette, and the Petri in no certain order. The Petri came out of a box of "stuff" my wife brought home from an estate auction. Dear woman!
