The focusing rack of my C330f jammed without any apparent reason.
At first I noticed increased resistance of the focusing knob when moving the rack out from the camera for about an inch.
Then I made several complete movemements of the rack from the rest position to maximum extension and back, the rack looked perfectly aligned and the camera has suffered no hit, but there was a noticeably resistance for the first inch of travel.
Today I tried operating the focusing knob as usual but I noticed a very strong resistance and didnt want to force the movement, the brake focus lever is not engaged.
I am wondering if this has ever happened to someone, I do not know of any Mamiya repairman in my area and I am looking for the C330 repair manual if someone has one to share
