    Hi people, I just registered because I'm having some issues with focusing.

    Let me start by saying that I am a complete novice to photography, and I never touched anything but compact cameras until lately, when I retrieved my dad's Yashica SLR from the depths of some cupboard.

    I'm now reading a lot on the internet, and trying things, but as said in the title, I'm having trouble with the adjusting the focus:
    The focusing distances on the lens simply don't match up with the distance the objects are away from me. I made a test to get it straight. I measured exactly one meter to the object, adjusted the lens to one meter - blurrrrr. To get the subject even remotely sharp, I had to turn the ring until infinity, and even then it wasn't that sharp.

    On the other hand, I can focus things that are only about 40cm from me blazingly sharp, even though the lens should just go down to 0,5, but to do that I have to set the focus to about 1m!

    What do you recon, is it a problem with the lens, or with the camera?
    Or am I doing something wrong?
    I have another lens, a Carl Zeiss, and it won't focus properly either, but I know my dad always said that lens wasn't working correctly...

    Thanks for any help!

    Hi and welcome to the forum. I does sound as though your camera is in need of repair. Has the camera ever been dropped?

    You can get another body for very little money if you find that the Zeiss is something that you don't want to give up.

    Just a thought, is there a detachable ring on the camera where the lenses go? If so, try taking it off. If you have to have it for the lenses to fit then make sure it's in all the way.

    Good luck and don't be a stranger. :)

    Sounds like the first lens has been taken apart ... and put back together incorrectly ... when it was put back together the lens was not aligned properly.

    Does the focus adjustment stop right at the infinity mark? Or, does it
    stop short? Go beyond it?

    Yes, I was told it could be that... but in response to compur, the marks line up correctly, looks correct.

    There are no extra rings attached.
    Can it be that it's something with the body, or is it most likely the lens? What could be wrong in the body? The mirror looks good, works even better.

    Based on your description ... I would say the lenses have a physical problem, not the camera body.

    Hi guys!
    I have an update: I received the outcome of the first film I shot, and to my surprise, all the close up pictures that appeared sharp are blurry, and all the landscape pictures I took, with the lens set to infinity, are perfectly good, despite appearing a little blurry when I took them! Also, on close shots, the pictures are most of the time cut-off on the bottom, as if I was pointing the camera up, which I wasn't, I remember them to be perfectly well aligned.

    So, what I think is happening is that the lens is working correctly, but what I see in the viewfinder isn't what is being captured by the film, right? This would point towards a problem with the body, perhaps the mirror? What do you think?
    Thanks a lot for replies again!

    Have you tried a different lens?

    Yes indeed, I tried the Yashinon and a Carl Zeiss, with similar results.

    Good thing there's plenty of cheap screw-mount bodies on eBay, huh? :)

    If I understand correctly, your test roll suggests that the image you see through the viewfinder is not the same as that which the film 'sees'. In addition, what the film sees apparently corresponds well with the actual distance markings on the lens. So it seems possible to rule out a lens or lens mount problem.

    A misalignment of the viewing system components [camera ever dropped or partially disassembled?] may be the culprit.

    Exactly, spot on.
    I went berserk and disassembled the whole upper part of the camera, because it's not worth traveling to Lisbon to have it checked out, I will get another body off ebay instead.
    So I just figured If I'm getting another one I'll check this one myself, see if I can see anything.
    In fact, I encountered a problem, and I thought it would fix my issue, but it didn't...one of the two springs that press the Prism against that focusing screen was disconnected, because a little plastic part was broken and so the prism was kind of loose and not really steady against the screen. I managed to fix it to that the prism is now steadily held down by the springs, but my problem persists. Everything else looked very good and securely in place.
    Weird, but well, now I know how the inside of a SLR camera looks, I guess I have learned something from this.

    I'll be looking for another M42 body on ebay, say, have you got any tips on good, sturdy, reliable m42 mount bodies that go for cheap these days, other then the Yashica TLs? I'll try to get another TL, I grew quite fond of this one, but maybe there are other ones that may be worth checking out?
