Hello everyone. This time, I bought this self-timer while I had a Canon Leica Barnack-type film camera, going around used camera stores. However, I never used it, but I was satisfied at a hobby level. I checked if it works, and there were no problems. When the timer ends, the needle comes out, and it seems to cut off without any issues. I don't have a Barnack-type camera now, so I couldn't try attaching it. Under these circumstances, I would appreciate it if only those who can purchase it and judge it from the photos would make a purchase. I think it's quite valuable nowadays, and I think it's a product that makes you feel the origin of timers. For those who can purchase it as a hobby, thank you very much.
