You have gone to the trouble of telling us NOT to touch the chemical, then you hold the lens with one glove and the cloth with acid in the other without glove...but, Thank you for the very interesting video ! Keep up the good work.
Helios 44-2 fungus: Take between 8 and 10 lenses. Remove front and rear element. Scarpe the fungus into a plastic or metal container. Add a little garlic and butter. Heat the fungus on a low heat for ~6 minutes. Serve with toasted bread on a vintage lens cap.
Hello! I know you specialise in Russian lenses, but can you give me an advice on how to clean the rear element group of a Super-multi-coated takumar 50mm f1.4 with a m42 mount? There are no screws on the back. I’ve searched all over the internet for some instructions on how to do this but nobody seams to have tackled this problem until now. Thanks for the great videos, they are really useful, keep up the great job!
In my lens (Industar-61 55mm) The first frontal ring turns for 90 degrees and then gets stuck and I cant get it out. I even tried brute force. Any ideas how to get i out?
hi, thanks for the very informative video, can I use the same chemicals on newer lenses ? will it affect the coating for newer lenses. I want to clear out the fungus of a new Samyang and Tamron lens inside the lens.
In case it helps, ~25% ammonia is the same as ammonium hydroxide, and is often branded as just 'Ammonia'. Ammonia is usually found in construction and paint stores. You wont mistake it for pure ammonia, which is a gas at room temperature.
Hi, is there any chance for you to make a video showing all cleaning process for nikon 80-200 f2.8 push-pull? I have one of these and I need to see a video step by step before. Thank you!
