    It could be that the proper focus point is beyond infinity on your particular camera, so no matter how much you compensate, you can never hit the true focus point.

    I'm not offering any excuses, there's a great deal of variation with these cameras (shoddy quality control?) but I know what my lens can do wide-open, so I know it's a good lens. Some people have taken the cameras apart and re-shimmed them. Personally, I wouldn't waste the time.

    you normally set up the rangefinder at 2 m cause that is where you are going to need it to be accurate.

    use a scrap SLR screen taped to inner rails

    Oh no, even if I must go 'beyond' infinity I can by merely loosening the screws near the helicoid on the top and bottom of the lens. THAT would allow me to turn the helicoid so that the rear element comes a tiny bit closer to the film plane.

    Christmas: NO, I think that infinity is the one best to anchor because that is supposed to be the 'ultimate' turn on the focus ring; the ring stops there and cannot go further. The other distances then 'fall into place'. - David Lyga

    I knew I had a pic someplace. Here's one taken with my G-III wide-open at F1.7, dust specs and all. Outside of standard sharpening, no Photoshop gimmicks. Im happy with it's performance.

    That woman is sharp but not extremely so. Wide open you did get a decent image but try using a Pentax A at 1.7 and see the difference with both acutance and contrast. - David Lyga

    Sure she's sharp. I mean good looking, as well as plenty sharp picture-wise. And if I was to run the picture through Photoshop, you think it was made by a Leica.

    And come on now. You really can't compare a 50mm lens to a 40mm lens, two totally different optical formulas being used.

    Remember that the Canonet is a mass-market, point-n-shoot camera from the 1970's. Considering that, it's image quality borders on spectacular. Plus it's small enough to fit in my pocket, so I carry it with me. Can't say that about my Nikon F, or your Pentax A.

    Looks like quite low light levels here, probably not the best for "pop" or micro-contrast.

    OK, I accept my forthcoming assassination. Kill peaceably. - David Lyga
