    Rangefinder focusing

    Hello,

    Sorry for this question, but I don't have too much experience with RF. I have one already, but not used it often, so...

    I bought new Bessa R2A and 35mm f/2,5 color skopar pancake II lens. I noticed next when focusing. Focusig is OK up to let say about 30 meters. At distances longer than that images do not intersect correctly. It still have double images even if lens focusing mark is on infinite position (end of focusing range). In my case I tried with building about 80 to 100 meters away. But, it seems that is not case when camera it directly pointed to object. If camera is at some angle regarding focusing object double image is shown. Then again it seems that when I move my eye a little looking through viewfinder there is no double image, that is focusing is accurate. And I noticed if I took camera down, and try to do the same focusing again, it focus precisely on that distance object. Those things never appeared at focusing distances shorter than about 30 meters, only on longer distances. And it seems only on horizontal camera position, not on vertical.

    Is that normal, that is do I have wrong eye position looking through viewfinder or camera is not OK.

    And regarding this, what I need to check and how, to make definite decision if camera is OK.

    I have camera for few days, and because of my work I couldn't yet shoot film and develop it to check...

    Thank you.

    Something appears to be wrong with the camera. Maybe something is loose, sometimes causing double rangefinder images. With the lens on infinity, there should never be a double image of a very distant object.

    I agree, rangefinder is out of adjustment.

    interesting

    It may be that diopters directly on your camera might work better than glasses, but it takes a lot of testing. Do you have negative diopter glasses (- x.xx) by chance? Unfortunately, if you also have astigmatism, the diopters can't correct for that.

    Try talking with an optometrist, and if possible with a camera vendor that has a variety of diopters available for testing.

    Thank you. Yes I have -2 diopter, and camera seller offered me to send diopter correction piece to try it. But, I will first shoot some photographs focused on different distances, print them on 30x45cm paper (I can't use slide film) and then will see...

    Than you all for answers...
