i just purchased a rollei sl66 mount 80mm f/4 lense with leaf shutter. now i have to ,a. buy a camera or, b. sell the lense. does anybody know how much these lenses sell for, this one is mint+, i looked on the net but only found the f2.8 w/o leaf shutter version. Does anybody want this lense/ Are the sl66 cameras reliable, they certainly have a lot of parts for the rise 8 degree rise built in, which is pretty cool. any experience or sugestions or comments would be helpful in figuring out what i should do, thanks.
