I love these videos.Even when I don't have the equipment shown there are usually tips and techniques that apply to cameras I do have.I'm slowly learning more and hopefully one day I'll be able to tackle some more complex things.
It's been 5 years since your post. The tools are not expensive if you plan your purchases, save your money, and only purchase those tools you really need, which will likely last a lifetime; you should continue to watch similar videos to learn how to adapt tools you already have to the work of repairing cameras and lenses. Yard sales, garage sales and estate sales are great sources of old, precision tools. A rusty tool costs little, but can be cleaned completely with fine steel wool and WD40 in a very few minutes. From TH-cam videos and old, used camera and lens repair manuals, you can learn what chemicals to use to clean lenses and camera internal mechanisms, and what to use for lubrication that doesn't melt in hot weather and drain internally onto lenses, aperture leaves and shutter blades. Rubber plumbing gaskets of the proper size can be used to remove and replace lens rings and lens elements on lenses for smaller cameras and both shutter and lens parts on view cameras. Good luck.
Thank you for these insightful and instructional videos. Will you please demonstrate the adjustment and calibration of the rangefinder coupling of a Summicron 35mm v.4 (c. 1982)?
The chunk you removed from the lens appears to be a flake of the black, anti-reflective coating in the interior of the lens. If I'm correct, it will likely continue to flake off over time and lens usage.
Hi - do you have any recommendations for what to do if there is a stiff focusing ring? That’s my primary issue so I’d like to go one step further than your video shows. Thanks!
I need to replace a broken focus tab/handle on my Summicron 35 version 3. I removed the rear spanner ring and focusing helical assembly as shown. For access to the tab/handle mounting screw, I seem to need to remove the spanner ring inside the assembly. It won't budge. I removed what appears to be a set screw in the spanner ring. Still won't budge. Any suggestions?

Dear Sir, I got a leica 50mm summicron rigid, which is quite dirty in the front lens group, can you teach me how to open the front lens group? Many thanks in advance.
Sir i have a summaron that i want to repair, the googled version, the vertical focus is a little off, it has to be the little circled glass on the googles but do you have any recomandations on how to disassembly leica googles?
I read that lenses must to be positioned in the exact position, not only regards the lenses order. you could correctly assembly it but however could compromised the lenses and their functionality. Is this true?
DO NOT completely separate the helical thread assembly, as it can be very tricky to reassemble properly. With that said work some isoprophyl alcohol into the threads and try to strip away as much of the old sticky lubricant as you can. astore.amazon.com/fixoldcam-20/detail/B01LX01Z0Q This product is also good to strip away old lubricant. Make sure you keep the flushed cleaner away from the optics as you do not want it trapped between the lens groups. After the old grease as been adequately removed apply a light synthetic grease.
First of all, many thanks for the reply. For what I have understand, I will disassembly the lens until what I see in video 1:04. Then I clean the focusing mechanism with isoprophyl alcohol. Then I put the new light synthetic grease. :)
Yes do what you can with the helical at that point. It is not recommended that you separate the helical threads for a complete cleaning without extensive experience in such a procedure. Once separated it could be an exercise in frustration attempting to get the helicoid reassembled to the proper timing sequence.
Probably not a proper video of complete disassembly, as the separation of fine thread focus helical and the subsequent reassemble is one of the most difficult and tedious procedures in repairing a lens. A work around, although not completely satisfactory is to work a small amount solvent into the threads to try and loosen the sticky lubricant. Than after the solvent as been allowed to evaporate repeat the procedure as often as needed to get acceptable results. Than a light lubricant can be applied over the remaining old lubricant.
Do not do it (just kidding)... The lens can be tough because the brass parts sometimes seem to be fused from age and grime. The careful application of heat from the tip of a soldering iron along with seeping alcohol around the fused parts. Or you could be lucky and your lens will come a part like easy as a late summer breeze. And DO NOT separate the focus helical threads. Very tricky indeed to re-thread the helical.
@@FixOldCameras After removing the retaining ring with a spanner wrench, the lens block separates from the focusing apparatus. Where should I apply grease to loosen focus? Finally, when rejoining the lens block to the focus apparatus, how do I ensure focus is accurate? Is there a particular position? Thank you!
I recently purchased a Canon Canonet QL17. The camera has a stuck focus lever and cannot be moved no matter how hard it is pushed. this is the only problem with the camera. could you make a repair video?
+gopernoper Thank you for the suggestion for a FOC video. There have been other Canon Canonet video request and they all have been noted. The videos are made in no particular order.

Thank you for this video. Will you do a video on fixing a tight focus ring on a Summicron 35mm V4?
Do you have a disassembly video for a Summicron 35mm 7 element?

Your videos are just so great ! After watching this, it became not as hard as I thought it would be, but I wish I will never use those techniques.
Thanks for the great comment and your interest in FOC.

where can i find this spanner wrench?
Great video. Where did you get the lens spanner wrench? Can't find a decent set online..

Is this true?
its not
So I have a summicron 50mm I believe. Its collapsable but the extension is very sticky
For smooth focusing, on Summicron 35, after disassembly, what to do ? I need to put my focusing mechanism more smooth... Many thanks

how do clean the front element or the group forward of the aperture ?
+mike hinkleman The "forward" lens group is addressed through the front of the lens. A word of note... the retainers at times can be very stubborn.
@@FixOldCamerasIs the retainer ring the one with the leitz Wetzlar lettering on it? How do you loosen it? Rubber stopper?
Thank you!
helpful!
I could get used to that jazz music
+Shawnee Union
Indeed! Might have to sneak in some more.
Except that was blues, not jazz.
Actualy my have fungus inside :/ I will send it to specialist. I don't think im manage to do this by my own :/ You have really steddy fingers ;)
