kuau Posted April 21, 2015 Share #1 Posted April 21, 2015 Advertisement (gone after registration) So I just purchased a used M9 with both a 28 Summicron and 50 Summicron, both 6 bit coded and newer models. Thank god my M9 is not showing and CCD corrosion. My issue is with the focus at infinity on both lenses, I did some quick test at both F5.6&F8 It looks like they are both front focusing, I.e. foreground seems more sharp then towards infinity Interesting I don't seem to see this issue with my older Zeiss 85/4 ZM which when turned to infinity it indeed sharp. Is my issues a problem with the M9 or the 2 Summicron or both? I was thinking about sending in the camera and lenses to stevecamera in Los Angeles, I live in Utah, or would it be better to send to Leica NJ? Thanks Link to post Share on other sites More sharing options...

friedeye Posted April 21, 2015 Share #2 Posted April 21, 2015 It just means your lenses need to be calibrated to your camera. I live in L.A. and have used Steve's several times with varying degrees of satisfaction, and always at considerable expense. Lens calibration is one area where I, personally, wouldn't recommend him. Better choice would be Youxin Ye, or DAG, or Sherry Krauter. Or, certainly, Leica N.J. If you're going to ship it, ship it to the best. I would, however, ask what the turnaround time is. You don't want to be waiting months to get your camera and lenses back. -- J Link to post Share on other sites More sharing options...
Lenshacker Posted April 21, 2015 Share #3 Posted April 21, 2015 Test your lenses wide-open, and with a test-target at a known distance and that you can measure the focus error. This will make it easier to determine the size of the error. Rangefinder lenses are usually optimized for wide-open work, normal lenses and wide-angle lenses have more focus-shift than long focal length lenses.

The OP suggests to me that both the camera and the Zeiss lens are off, but happen to work well together. Send the whole kit to an independent repairshop to be sorted, would be my advice, as Leica will not adjust a Zeiss lens. Link to post Share on other sites More sharing options...
kuau Posted April 22, 2015 Author Share #5 Posted April 22, 2015 Jaap. The Zeiss is the only lens that does work as expected. It's my 2 Summicron's that are off. I will do the test again today wide open to see where I am at. Thanks Link to post Share on other sites More sharing options...
Geoffrey James Posted April 23, 2015 Share #6 Posted April 23, 2015 My 35 Zeiss 2.8 is ridiculously sharp at infinity-/ in fact at any range, to the extent that it created artefacts on the M9. I am hoping this won't happen on the M. It's a pain in the a. Link to post Share on other sites More sharing options...

I will do the test again today wide open to see where I am at. Thanks Which does not mean the Zeiss is correct. It just happens to be correct with the camera body that may well be incorrectly calibrated, given that two Leica lenses are similarly off. The vast majority of newer Leica lenses are spot-on. You need to get the whole system calibrated as it is unclear where the fault lies, and it may well turn out that only the body and the Zeiss lens need work Link to post Share on other sites More sharing options...

What distance are you taking true infinity to be? Infinity when photographed is often softened by atmospheric haze. Steve Link to post Share on other sites More sharing options...

You need to get the whole system calibrated as it is unclear where the fault lies, and it may well turn out that only the body and the Zeiss lens need work I'm pretty sure this is what I was saying earlier in the post, Jaapv. However, you're saying that the fault must lie in the camera and Zeiss. That's likely, as cameras can fall out of adjustment easily. Not so lenses. My point was - the OP should send his kit into a reputable repair facility to be calibrated. Heavy use professionals will often do this as a matter of course.

gunston Posted April 26, 2015 Share #10 Posted April 26, 2015 only zeiss would work properly without calibration Link to post Share on other sites More sharing options...
