Yashica FX-2 shutter and focus problems

    Hi all,

    Does any body here have a Yashica FX-2 SLR? It is a very old one.

    I recently bought mine on ebay, and shot five rolls. The results were
    quite suprising.

    Firstly, the pictures seem totally out of focus, although I am pretty
    sure I focus to the clear image in the viewfinder. The focus seems to
    be a bit behind the object being focused on. I also noticed that the
    lenghts shown on the lens is the the value it supposed to be

    So, is it the viewfinder's problem? Any way I can fix it easily?

    Secondly, there are quite a number of photos with images on the right
    hand side, and black on the left. I suspected it's the shutter not
    working at 1/1000s. Any easy solutions? I am avoiding the high speeds
    now by using slower films.

    Thirdly, whenever I shot at 1/60s, the mirror locks up afterwards, so I
    have to shot in black for the next frame.
    The mark on the 1/60s is in different colour to that of other speeds, I
    suspect if there is a trick to use this speed. Any one know this?

    Thanks in advance.

    A black partial frame when not using flash is indeed a sign of shutter
    problems but you might be able to "exercise" that out simply by cocking and
    firing it enough. You can open the back and look through the shutter to see
    if the light circle appears complete.
    1/60th is in a different colour usually to indicate that is the highest
    flash synch speed. It should not lock up the mirror.
    Can't help much on the focus problem. Are you using a large opening lens
    (like a 50 f1.4) wide open? While checking the shutter you might also make
    sure the diaphragm is closing down.

    Thanks for the reply.

    Yes, as I expected, the 1/60 should be a mechanical failure. Avoiding
    it at the moment, as well as the high speeds. The photos took with
    medium speeds seem still in fairly good quality.

    I use a 28mm f2.8 and a 55mm f2.0 lens, and do use them wide open quite
    often. I had the thought that the out of focus problem being the depth
    of field is too narrow and it is hardly to observe much change in focus
    on the viewfinder screen.

    However, I am not too sure about the diaphragm you are talking about.
    What is it?

    Thanks.

    The diaphram are the "leaves" in the lens.

    Hi Peng,
    I used to have an FX-2, but it developed the same fault you mention in
    your third point, i.e. locking mirror, principally around 1/60,
    although it could also happen at other speeds. Unfortunately I never
    knew the cause, but it does seem to be a common problem. The reason
    for the different colour of that setting is that it is the flash sync
    speed.
    Cheers,
    Mark

    Good place to send your camera in for a Clean and Adjust. Not a
    unreasonable thing for a 30 year old camera to need.

    the aperture that closes down for any shot at a higher f stop than the lens
    wide open. You should be able to see the blades when the lens is stopped
    down. Try shooting with the back open and watch for the difference between
    f2.0 and f16 on that 55 mm lens. Every other setting should be somewhere
    between them.

    I am sure the blades closes down at different stops, as I got plenty of
    photos correctly exposured with lower aperture.

    Thanks for help.

    Hi garlicpic,
    It seems that the problem is quite common then. I have been avoiding
    1/60, and it seems worked. Haven't gone into trouble much now.

    I noticed when I switch from 1/125 over 1/60 to 1/30, I could hear the
    sound of gears spinning fast. Could be a problem.

    Thanks for the advice on flash sync. Very helpful.

    Thanks for the advice.
    Unfortunately, I am in the UK. And even worse, I cannot afford to spend
    another big lump of money to get it serviced.

    Cheers.

    You cannot tell from prints. So unless you are using slide film there is
    no way to tell without visual verification.

    Yes, I will have a look next time.
