    I just received a Fuji GS645 fold medium format camera and the focusing is weird...

    When I look inside of viewfinder, the translucent part/patch is on the left to subject and it moves to right when I start to turn the focus ring clockwise. It changes from seeing a double image to the two images being completely aligned.....of course...and then when I turn the focus ring all the way to right than the translucent also move to the right side of the subject but the problem is when I turn the focus ring back to left, the translucent part won't move until I close the lens and reopen. The rangefinder patch is just stuck at the right corner....The lens moves back and forth tho.

    When I turn the focus ring about 70% to the right then if I turn it back to left, the translucent part does moves to left.

    There's no battery or film in the camera but I don't think they are causing the problem with focusing...wouldn't they? I've heard the battery is for meter only...

    Does anyone know what's causing this?

    Thanks,

    Optimistic guess: dried-up lubricant makes the RF mirror stick at one end of its travel. Pessimistic (and unlikely) guess; some part bent or worn out of shape causing friction at end of travel. Remedies: a) work the focusing mechanism back and forth, hoping to free the stuck lubricant; b) return to seller; c) repair (self or professional)

    Camera needs CLA--old lubricant and dirt. Seen it a million times to where there's no point in even asking about this kind of thing any more. Always the same answer. There is no other answer.

    I have another answer....buy a Bessa R. You'll thank me afterwards. I have spent many hundreds of dollars on CLAs for Russian cameras and not one of them worked right, no matter who did the work. Oleg, Fedka, etc. I have spent zero dollars repairing Bessa R cameras, and every one of them worked perfectly as soon as I unpacked it. Others may have had different results, this is mine.

    Definitely get a CLA - the Fuji rangefinders are great little medium format cameras. Worth it.

    The OP has a Fuji, which I believe is Japanese... and medium format.
    Tangentially, my Kiev functions just as it should and shows every sign that this state will continue indefinitely. :smile:

    On topic, there is stiff lubricant in the RF mechanism, it needs cleaning.

    Thanks guys.

    Is it okay to change the shutter speed when the wind lever is cocked?
