Sorry but only putting in zippo gasoline to clean slow speeds will make the camera work in the short term, but in the long term it will wear out very quickly. The low gear mechanism needs to be lubricated sparingly with oil spike.

Thank you so much for this video! I've used this before to clean up the fungus on the viewfinder. Now I'm having trouble with my frame counter resetting to S. It only gets to 6 and refuses to go back to S. Would you have any tips as to how to fix that? Thanks

Thank you. I had fungus inside the front window and spent an hour trying to unscrew it before seeing you could just pop it clean out.

Thank you. Very useful.

Thank you for this video ! It helped me to tension the first curtain on my Canonflex from 1959. At 1/1000, it was visible that the second curtain had more tension than the first. As a result, there was no exposure at 1/1000. After tensioning the first curtain by about 1 1/2 turns, the exposure at 1/1000 is good now (I compared it to my trusty F1). The way you explained and showed how to deal with this issue in your video gave me the confidence to do it ... and it worked. Thankx !!

Shot in dark here, but my Canon P has a shutter advance lever that sometimes locks up. Almost like something is in its way. You ever see anything like that on these guys? Loved the video. Appreciate your time.

could you do a video for the Canon 7 please?!?!?!?!

Thank you for going through all the facets of refurb'ing this camera!

great video. thanks.

Thanks for the video! Super helpful. What kind of lubricating oil do you use?

Be careful when removing the first glass on the front of the Rangefinder if you also want to clean the inner glass. The two are connected by an adhesive layer, so the Rangefinder will become blurred when you separate the two glasses. We carefully removed the adhesive layer with nail polish remover and a cotton swab and then the Rangefinder is clear again.

This video saved my butt. I got a super good condition Canon P recently and shot a whole roll through it only to notice my negatives were 1/3rd cut off consistently. I attempted the lighter fluid fix one time, but didn't help (and I ended up scratching the locking nut on the tripod mount pretty bad, !!!), so I took it to a repair shop, where the guy there said he wasn't comfortable working on it due to his older age and possibility he might damage it worse, and he said it's probably the shutter brake, and would need to be taken apart quite a bit more to analyze (I appreciate this because of the money I am going to save). Anyway, I came back home and watched this video again, and noticed the arm next to the black spinner shaft wasn't moving on my camera when I was cranking it. I decided to apply a little more naptha on that specific spot and pry it a tiny bit and amazingly it came loose and now my shutter works as expected!

Superb video with thorough detail, suitable cautions regarding easily-damaged or lost parts, and fine pacing. Many thanks!

Thank you for offering such knowledge up for learning, and keeping camera repair (and cameras!) alive!

Thanks for your comments about the canon 7sz. Today I managed without damaging the flash sync to remove it without drilling the holes. I gripped the outer collar with a padded wrench and a quick twist and it was lose. The black wire to the light meter is really buried deep so I'll solder to existing and test for resistance. If the meter will not work it's no big deal but I only want to clean the glass and put the top back on. The front glass has no protection and can be easy to mark if your not careful taking the cover off. Many thanks.

Wonderful instructions, thank you.

Hey, great video! Thanks a lot for filming and uploading this very useful guide!

Thanks for this! Had a slow moving rangefinder cam (when focusing close quickly the rangefinder patch would take a second to catch up to the lens) and thanks to this video was able to take off the body, put a dab of lube on the mechanism and now it works perfectly.

Thank you Jim, this very useful again!

Hi thank you for the video! This helps greatly on my canon p! Unfortunately my canon p has a fungus on its prism, Would love to see a video on that! Thank you again!
