On my research for the best way to use one camera on the street, I have come a long way with different experiments as many others before.
I think, I arrived at a satisfying solution for myself, even at an affordable price point.
I found, using a good fitting wrist strap on lighter cameras as Nikon MF film bodies, Leica M cameras, even small bodied DSLRs with compact lenses or PS cameras is very convenient and comfortable to use.
I made a short writeup, how I made my own perfectly fitting strap in my new article section on my web site.
The link to the section is here:
I hope, this helps others too.
