fenykepesz Posted November 24, 2021 Share #1 Posted November 24, 2021 Advertisement (gone after registration) it's not even so cold this morning, -4°C perhaps, but focusing seems to be blocked inside my M10-D body. it's the metering field or patch that doesn't move much and is stack on infinite distance. knocking a bit on the camera body helps perhaps for a single stride but then again focusing freezes. i feel i am back to 'manual' focusing à la my little Rollei 35SE, looking at the metering index on its Planar lens and setting distance that way. anyway, i remember i had this issue already some year ago. detaching & reattaching the 50/1.4 lens is of no big help. now, ½h later, things improved, no clue why, but this focusing issue seems to come & go for no apparent reason. temperature may play a role though it's not even truly cold yet for Montréal... any suggestion for a home-based solution ? i hate the thought of a trip to Wetzlar.

Advertisement Posted November 24, 2021 Posted November 24, 2021 Hi fenykepesz, Take a look here focusing with my M10-D seems to 'freeze' literally. I'm sure you'll find what you were looking for!

fenykepesz Posted November 24, 2021 Author Share #3 Posted November 24, 2021 thank you, Jess - this is a truly informative and helpful link you showed me. the focus coupling arm is indeed stuck in the fully inside position (or in other less deep positions), and doesn't always jump out as it should. let's find now the appropriate screwdrivers in my toolbox and see what can be done tonight... a last question is what oil/grease/lubricant to use (though i guess that too depends on the type of problem my camera has which i have to find out first). yes, correct, focus patch, not metering patch - thank you !

fenykepesz Posted November 25, 2021 Author Share #4 Posted November 25, 2021 thanks again, Jess - this post here by MaxHu describes exactly my problem : a friction area with a scratch inside the focus system that may need a drop of some sort of lubricant - just which one ? in any case, your advice was very helpful - thank you ! opening the top part was easy, goes with two screws.

fenykepesz Posted November 25, 2021 Author Share #6 Posted November 25, 2021 (edited) it's crazy, the tiniest amount of WD-40 did the job, applied with a pointed plastic pin - no friction no sticking anymore ! focusing works again as before ! the pink line in the photo circumscribes the area of friction. as one sees it wasn't even necessary to detach the top place - i just lifted it a bit, perhaps 2cm. uff - ende gut, alles gut - Jeff, thank you again ! though next time i may want to use a more suited lubricant...

AndreasG Posted November 25, 2021 Share #7 Posted November 25, 2021 Advertisement (gone after registration) Good to know, thank you for the photo, which clearly explains, where to "repair". WD-40 is as you point out certainly not the best choice as a long term lubricant, I would prefer (in case my M10-D shoes the same symptoms) watchmaker's oil. 1 Link to post Share on other sites More sharing options...
fenykepesz Posted November 25, 2021 Author Share #8 Posted November 25, 2021 yes, AndreasG, good point, 'next time' i will use a watchmaker's oil. yesterday on my way to work, going on a 'blind' focus date, i shot this b&w picture with my sticky-frozen M10-D, setting distance just by looking at the meter scale of the Lux 1.4/50. luckily that ancient technique still 'works'. i converted then the raw color DNG photo to b&w with the gimp/gegl/c2g algorithm using standard settings and without any manual retouché of contrasts or lights, taken out of the box as is. i love this c2g tool. today my M10-D feels again like a well-oiled motor. 2 Link to post Share on other sites More sharing options...

You are welcome, glad to know it is fixed. those two metal part are very robust, the friction won't harm the focusing accuracy 1 Link to post Share on other sites More sharing options...
fenykepesz Posted November 30, 2021 Author Share #10 Posted November 30, 2021 i had to look around a bit and explore what watchmaker's oil to purchase and decided to go with a synthetic evaporation-resistant oil 9010 by Moebius : see here and here for this product. once the 2ml bottle arrives i will post here again to let the interested members know about my experiences in lubricating the M10-D's focusing mechanism with this oil.

Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members! WD-40 is for multi-propose (lubrication, stain cleaning, anti rust, loosen screw ) , and it serve well. My suggestion is: 1st: clean surface with WD-40. 2nd: use cotton stick clean surface(remove small shards). 3rd: smear action surface with a pencil (leave some graphite on it，this is very important and durable) 4th: apply some high speed liquid bearing lubricant. I did those to my camera half a year ago and it still work well, even smoother than before 1 Link to post Share on other sites More sharing options...

I just did the same fix on my M262 after experiencing the sticking focus mechanism today. Frankly I was a little frustrated with the thought of losing access to my camera for weeks or months. I used your photos and description, along with an ultra fine synthetic lubricant intended for very small bearings (<1mm) against flat steel. Just the tiniest smear and the severe sticking disappeared. Barely lifted the top cover 1cm to access the mechanism. I can’t thank you and @MaxHu enough.

jon595 Posted December 1, 2023 Share #14 Posted December 1, 2023 I also did this with my M10 a few days after buying it used. It looked scary at first, but it really is an easy fix as long as you don't rush it. I ended up using some high temp grease I have for certain firearms. A very tiny dab was more than enough. 1 Link to post Share on other sites More sharing options...
