Have any of you got experience with repairing the rangefinder mechanism in a fuji GSW 645 (the 60mm lens, non-folder)? I've got the option to get one with a rangefinder that "sort of works" (it is very sluggish but eventually the split images reach the proper registration which appears to match the focus distance). If the rangefinder is sluggish like this, is it likely that all the components are functional but just require lubrication or a reseating or something? I've heard that parts are difficult to find for this camera, and I would like to get the rangefinder working. The rest of the camera is in great shape, so it would be a fine portable landscape camera for hyperfocal / scale focusing.
For the ten years I lived in France, the Fuji was my constant companion. It went everywhere, including biking in Brittany, where, dangling from my shoulder, it slipped off, banged into the front spokes, and had the front lens cell (containing aperture and shutter speed ring) ripped violently off. I looked inside the remaining bit of the lens, discovered that the three tiny screws that held it on were still intact, took it to our rented cottage, and on the dining room table with my jewler's screwdrivers and a pair of tweezers, managed to get it together again. I had got the position of the thingy's that move the shutter and aperture wrong the first try, disassembled and reassembled it, and it's worked fine ever since. A little loose, but it works just fine. That was about 8 years ago. The rangefinder sticks a bit, but you can loosen it yourself. The little frame around the window pops off, and the window glass lifts up on a tape hinge. Handle it carefully, but you can get the rangefinder unstuck. Now, when it sticks occasionally, I just give the camera a good thump with the heel of my hand, and the rangefinder works again. When this camera finally dies, it won't owe me a cent of the $600 (new price) I paid for it about 15 years ago.
It has now entered semi-retirement, serving as a backup to my Mamiya 7, but it will always have the distinction of having given me some of my best travel photos. I also have its whiz-bang sibling the GA645Zi which I use almost always for color and love as well.
Camera Wiz should be able to do the repair for you as long as it doesn't need parts that they don't have or can't be had. They're getting scarce.
