Michael Geschlecht Posted November 9, 2017 Share #243 Posted November 9, 2017 (edited) Hello Everybody, Acetone in nail polish remover sometimes contains oils & other ingredients which may leave unwanted residues when they dry. This is done so that the acetone does not dry out people's hands. If you use acetone for cleaning it is better to buy it as acetone alone without other ingredients. It is best to do this in the smallest metal container that you can because acetone is easily ignited & it is EXPLOSIVE. It is important not to smoke or have open fires nearby when you are using it. It is also good to keep the cap on the container as much as possible while you are using it.

gippo Posted November 9, 2017 Share #244 Posted November 9, 2017 hello, thanks for clarification, I wonder if you can use some other solvent easier to buy and that you do not leave any residue after evaporation?best regards Link to post Share on other sites More sharing options...
jdlaing Posted November 9, 2017 Share #245 Posted November 9, 2017 Lacquer thinner may work. You only want to soften the seal, not remove it, enough to be able to turn the cam. Link to post Share on other sites More sharing options...

gippo Posted November 9, 2017 Share #247 Posted November 9, 2017 Advertisement (gone after registration) Thank you all for the answers; after changing a screwdriver for the purpose, I did the modification without needing to soften the paint; it was already soft. Now everything is ok, and I thank the TH author and all those who helped to make it all simple. Best regards Link to post Share on other sites More sharing options...

jdlaing Posted November 12, 2017 Share #249 Posted November 12, 2017 (edited) Yes you can. A small amount. That’s lacquer not enamel. Edited November 12, 2017 by jdlaing 1 Link to post Share on other sites More sharing options...

qwertyaus Posted November 19, 2017 Share #251 Posted November 19, 2017 Another comment to confirm this method works. My Leica M9 showed significant issues focusing when it came to infinite, being off (in the rangefinder screen) by about 2-3 mms. I am confident it was the body, and not the lens. This took a couple of hours to figure everything out, but I set up a focus testing image on my laptop, set my camera at 45 degrees to it, then slow began the process of making changes to the rangefinder hardware at infinite focus, 1 meter, and 2.5 meters, until I was happy with the results. Do have a good screwdriver; do not buy a tacky, cheap product from the local cornerstore. Purchase a file and manually reduce the size of your screwdriver until it perfectly fits the 'A' screw. You only need to make minuscule changes to see results in the rangefinder, so take your time. This is not a complicated process, and I find it hard to understand why a lot of people are so daunted by getting hands on with their equipment. Provided that you are slow, methodical, and deliberate with your changes, you will not (and dare I say can't) break your beloved Leica camera.

lexontario Posted July 7, 2018 Share #254 Posted July 7, 2018 Hi new to Rangefinder. My focus seems off. My question is on how to check at infinity. From what i have read, to focus at infinity I set my aperture at the desired F stop ( 16 or 8 or 4) then set the infinity marking on the focus ring to align with the coresponding number on the lens closest to the body. So with the above method my 21mm F3.4 set at F16 aperture and the infinity mark aligned 16 looking at the moon the two images are out of alignment alot. With the aperture set at F8 it is still misaligned. Only when I move the focus ring all the way, so it is aligned with the centre marking 2.8 , then the images overlap perfectly (in focus). This is the same for my 28mm 2.8 and also my 50mm F2. All Leica lenses. Seems the wider the lens, the more the two images are separated from each other when checking at F16 Am I focusing at infinity correctly ? Link to post Share on other sites More sharing options...
gippo Posted July 7, 2018 Share #255 Posted July 7, 2018 sorry but I did not understand the question; probable for my modest English. Infinity over RF occurs regardless of the aperture set on the lens. practically:insert the optics; rotate the barrel up to the stop point (towards infinity); at this point the image in the RF box must be perfectly superimposed or unique.If there is duplication of image it means that either the optics or the RF are to be calibrated.I hope I have been of help Link to post Share on other sites More sharing options...
ianman Posted July 7, 2018 Share #256 Posted July 7, 2018 (edited) It sounds like you are using the depth of field scale to focus. This means that all planes at a distance within the two equivalent aperture markings will be within an "acceptable focus tolerance" (read up on circle of confusion for an explanation). If you want to focus precisely the distance to the focus plane should be indicated by the central mark of the depth of field scale.

lexontario Posted July 7, 2018 Share #257 Posted July 7, 2018 Thanks for responding. So I think I am describing setting hyperlocal distance. How do I set the lens to infinity ? Link to post Share on other sites More sharing options...

ferdlmm Posted February 22, 2019 Share #260 Posted February 22, 2019 Thank you so much for this amazing thread!!! My M10 was killing me...it had backfocus and all I did was adjust the „B“ screw with an allen key. Know the rangefinder focuses razor sharp from zero to infinity. Took me 5 minutes instead of having to send the camera to leica and having to wait several weeks for it to return! Link to post Share on other sites More sharing options...
