You are right about that. Good prices on those old Canon (I presume, lenses.) One of my favorite cameras is a 6x6cm 120 Twin lens reflex, Seagull 109, that I picked up in China a few years ago.  It cost $200, including a leather case, from the factory in Shanghai but can be had for $279 in the US.  It has an old style taking lens (75mm f3.5) similar to one of the older Zeiss designs and although not as sharp as the newer ones, it's plenty sharp. It is all manual winding and focusing and has no meter but does flash sync up to one 500 hundreths of a  sec through a PC sync connection.  It's light and compact and I've used it with studio strobes and on camera small flash as well as in ambient light situations either estimating exposure or using reflective or incidence meters.
