I left the M's shoulder strap in the camera box since day 1, until lately I need a camera strap for my Nikon Z that comes with a fugly strap. I realize the Leica strap is actually a very good!! It's very easy to put on or remove, the buckets is not touching the camera body and it's light weight. I think I have really brain washed by seeing too many M with leather strap on the internet, so I kinda automatically went to buy a leather one without checking it out first.
