jaeger Posted August 22, 2019 Share #1 Posted August 22, 2019 Advertisement (gone after registration) It's a mechenical and somewhat technical question... 1) do you have any Leica lens can rotate beyond minimal distance for example 0.7 on most lenses. I didn't ask whether you can focus with it or not, I am asking just the mark goes beyond minimal point, please see picture*. If so, I have another question for you to help me. 2) is there a focus ring stopper inside the lens @ minimal? if so, is it adjustable? 3) is there a focus ring stopper inside control by the body in this regard? I can see a stopper for the cam but it seems only disengage after it's limit, which I already don't think so - but no harm to ask. Thank you in advanced. Welcome, dear visitor!

TomB_tx Posted August 22, 2019 Share #2 Posted August 22, 2019 Most of mine go somewhat passed the last mark. As long as it at least gets to the mark it’s OK. Link to post Share on other sites More sharing options...

lct Posted August 22, 2019 Share #4 Posted August 22, 2019 Most if not all my M lenses pass the mark. They have no stopper fortunately, this way they can focus closer than 0.7m on mirrorless cameras. Link to post Share on other sites More sharing options...
Michael Geschlecht Posted August 22, 2019 Share #5 Posted August 22, 2019 Hello Jaeger, When you are focusing with a Leica "M" range/viewfinder & you reach the limit of close focus for it: The movable rectangle will stop moving. If the rectangular rangefinder patch is moving then the system is displaying where the plane of focus is. Best Regards, Michael Link to post Share on other sites More sharing options...

Best Regards, Michael I did not pay attention to the last little extra turn actually not moving the focus patch because the RF stops at 0.7m. Although I don't do that much but it does make the closest shoot out of focus. It took me a very long time to figure out why. Is it possible to correct the stopper at 0.7m?

TomB_tx Posted August 23, 2019 Share #7 Posted August 23, 2019 Advertisement (gone after registration) The RF on both my M3s stop focusing as they reach 1 meter (the original close limit), so all the newer 0.7 lenses go well past their RF limit. After its CLA my M6 RF stops BEFORE it reaches 0.7, so it also takes care. I’ve just learned to watch where the RF patch stops and back focus up a bit to stay in the usable range.

albertknappmd Posted August 23, 2019 Share #8 Posted August 23, 2019 They all go beyond but no stopper is available or needed. Albert Link to post Share on other sites More sharing options...
Pyrogallol Posted August 23, 2019 Share #9 Posted August 23, 2019 I have read a similar thread recently, same answer, many lenses will go a bit further than the engraved distance scale and closer than the closest the rangefinder will couple.

The RF of M cameras doen't work below 0.7m but lenses going closer are easy to focus with mirrorless cameras. Link to post Share on other sites More sharing options...

Harpomatic Posted August 26, 2019 Share #13 Posted August 26, 2019 I’m going to be controversial, I know, but: what everyone is happily admitting is that lenses that cost several thousand pounds (I’m in UK) or used to cost a lot in their time don’t have a proper build quality to stop the focus where it should? Whereas “cheapo” CV and ZM lenses do without a problem, or tell you before hand they go closer and give you the proper scale? I’m talking as a Leica user, camera and lenses, but in my opinion everybody makes excuses where there are none. These lenses were not built for mirrorless. They should stop where they are supposed to according to the focus scale - rack the focus to the MFD and you know where you are - or rather not, with Leica lenses!

jdlaing Posted August 26, 2019 Share #14 Posted August 26, 2019 If you “rack it” to a physical stop and don’t use the viewfinder and rangefinder patch for focus you deserve what you get. The same goes for infinity. Link to post Share on other sites More sharing options...

The same goes for infinity. Who said I don’t use the viewfinder? When you need to focus as close as possible you rack it to MFD, then rocking slightly back or forward you find the alignment in the focus patch and you get perfect focus a unless the lens doesn’t stop at the right point! Then the focus patch tells you nothing about where the close focus is Edited August 26, 2019 by Harpomatic Link to post Share on other sites More sharing options...
jdlaing Posted August 26, 2019 Share #16 Posted August 26, 2019 Nobody said you don’t use the viewfinder. Relying on the stop is bad news. Even when they are right at the correct position they wear over time. Demanding that the stop be set at minimum oe maximum marked positions is fruitless.

I hear your point but I still think it’s making excuses. Relying on the stop is bad news?

Leica RFs are limited to 0.7m indeed but nobody's forced to use the RF for focusing. There were measuring tapes when mirrorless cameras were not yet invented . BTW Leica is not alone, my CV 21/3.5 & 35/2 do pass the MFD as well, rightly so in my humble opinion. FWIW. 1 Link to post Share on other sites More sharing options...
