mby Posted October 27, 2009 Share #1 Posted October 27, 2009 Advertisement (gone after registration) Wasn't there a recent thread telling us that specifications and tolerances on M9s are now much tighter, so that you don't necessarily have to send in your M9 to have lenses adjusted? - Unfortunately I can't fnd it anymore in the forum. Maybe somebody can confirm? Thanks and best regards, Michael Link to post Share on other sites More sharing options...

Ario Arioldi Posted October 27, 2009 Share #2 Posted October 27, 2009 I do not have any focus issue with any of my lens wich work fine on both M8 and M9. Cheers, Ario Link to post Share on other sites More sharing options...
novice9 Posted October 27, 2009 Share #3 Posted October 27, 2009 I have never owned an M8, but I can say that my 35/1.4 ASPH works perfectly on my M9, no focus shift whatsoever perceived, front or rear, after about 500 shots, including a set of testing (admittedly not scientific by some of your standards but fine for mine) on this specific issue.

BerndReini Posted October 27, 2009 Share #4 Posted October 27, 2009 First thing I did was test all my lenses and there was no correction needed. I will say though that every lens focuses slightly differently, but only in the range of a half an inch at close focus. The focus is very critical with the M9 if you pixel peep at 100% due to the size and resolution of the sensor. The rangefinder was definitely adjusted really precisely. Also, I just bought some sensor cleaning swabs, but right out of the bag, the sensor of the M9 was perfectly clean without any of the grease spots I expected. It seems like someone learned from their mistakes over in Solms. Link to post Share on other sites More sharing options...

It seems like someone learned from their mistakes over in Solms. I found the same, every single one of my 12 lenses of various vintages from 1939 to 2009 focus perfectly on the M9. With one exception, out of the box, my sensor looked as if someone at Solms had their eaten their bratwurst all over it, the sensor was covered in grease spots, it took me 1/2 an hour to clean up the mess!

BerndReini Posted October 27, 2009 Share #6 Posted October 27, 2009 Hahaha, that's why I ran out and bought the swabs in the first place. I didn't want to get my arctic butterfly dirty, but as I said, mine must have gotten special treatment this time. "Hans" was more careful in QC than "Franz" because he knew I would come after him on my next trip back home. Link to post Share on other sites More sharing options...
