Focusing error of Summicron 75mm on Leica M9??

Mine has been back as well..... OOF at infinity

 

Now it's ok at infinity and for close.... but inexplicably out at 2-3m.

 

Only noticeable wide open when taking pics of flat objects perpendicular to the camera.....

 

Not sure I can be bothered to send it back for another go....

 

The DOF characteristics wide open are almost identical to the Noctilux 0.95 so its not surprising its a challenge to get images spot on.....

I also have this problem. I amsending the lens now to solms to get6bit code and te get checked up. I hope they will fix it.

I am in a similar situation with a 75 Summicron and M9. I'm having the same issue, other lens focus fine, but the 75 just has a problem. When focussing on something near it's fine but once you try to focus at a distance there are issues.

 

I set the M9 on a sturdy tripod, focussed the lens to infinity and f16 and took a shot into the distance, nothing was in focus. I then removed the 75 and put another lens on with the same settings and it is fine.

 

I had the lens serviced, they said they adjusted back focus, it came back slightly better but still nothing would focus at infinity or at a distance.

 

People who are mentioning the viewfinder or depth of field or even user error as the problem, I can't understand how when set at infinity (thus removing the rangefinder or viewfinder and couplings from the equation) and using a tripod and a small aperture (for maximum depth of field -- which should in theory in my examples from about 10 metres to infinity), how these could cause such an issue.

Thank you all for the detailed replies!! I really appreciate it.

 

My experience is closer adan where from 1-5m it seems okay, but outside of that range, the focus seems to be off all the time. And I also have the

 

I currently do not intend to add a magnifier since I intend to do 35+75 combo on the street like elgenper. It'd be too cumbersome to have to take on and off the magnifier all the time. I just hope that 75 focuses reasonably enough.

 

In any case, I'll keep shooting for another couple of days. I suppose if the lens does need calibration, it'd take too many weeks before it's done that it'd miss my Paris trip in October. I think I'll just stick with it as is for my Paris trip and send it to Leica NJ as suggested by matlep.

 

Thank you all for the infos!!

I got a Walter eye piece and my hit rate with all lenses 50 (especially Nocti at f 1.0) and up is now phenomenal. I do not own a 75, but my 90 and 135 hit rates are much better after installing that eye piece. If you have any astigmatism it works wonders.
