I must amend my previous Ques re: Horseman 910 to Horseman 980-my error. I shot my first roll to check out the lenses at various f stops. At 3.5 with the 105mm topcon pro I was horrified by the lack of sharpness @ 11x14 magn. I couldn't bel ieve Topcon could make such a terrible lens. Something must be wrong! When I mea sured the distance from camera back to the film plane and the back to the ground glass Irealized that the previous owner had the Glass in BACKWARD-maybe that's why he sold it!!! I still want opinions on the camera and its lenses-a 105 & 180 .
