So, I'm contemplating the above camera for studio portrait work exclusively (duh).

But, have no idea what the fair market value is for something like this. It comes with a

Wollensak Betax No. 5 lens. : EQ. 12" 304.8mm F4.5.

It appears to be in good condition. I haven't inspected it yet in person.

What do you think? My guess is $400 - $600??
