[Leather] Can't find much review and specs online and I hope this will help those on the fence.

I bought the vintage brown color strap. The quality of the leather is better then I expected. For those who bought the vintage brown Leica CL and M10 leather protector, the color of this strap compliment nicely with the half case.

The leather is stiff and I believe it takes time for the leather to break in.�

The length of the strap is adjustable. It is roughly between 93cm - 118cm in length. It has a well-built metal buckle for length adjustment.�

Overall

[Leather] Well-made, nicely contoured, well worth the $$ to keep my new M10 Monochrom in good shape.

[0.14 lb] Beautiful leather case provides a clean minimalist look with the LCD cover flap. Perfect fit and protection. Basically just turned my M10-R into an M10-D.

[0.14 lb] I've never owned another Leica camera case so I have no comparison. But I like this case very much. It offers the protection that I need. Now I don't worry dings and scratches.

[0.14 lb] Fits quite snugly to my M10-P Safari edition camera body. The back cover protects your LCD screen. It is a must for Leica M 10 camera. I have ordered one for my M10 Monochrome.

[0.14 lb] Really nice! Wish it was only a few mm larger so it wasn't as tight a squeeze and it had less of a chance to change the focus as a result. Also need to have a thin strap like the PD Leash to have it fit on the camera strap. If you use something wider, or something like a climbing rope version, it either won't fit on the strap or will bend in enough to make the right fit just that much tighter. Love it though.

[0.14 lb] I have a Leica M6 with red buffalo leather, the original come with black strap, looks wired. The one I got from B&H is perfect match with my camera. Love it so much.
Btw, delivery very fast

[0.14 lb] You can see, feel and smell the quality of this leather neck strap!  For all the simplicity of the design, the length of the strap can be easily changed, something that puts it streets ahead of many other straps.  I have attached the strap to a Fujifim X-H1 camera. Although the camera is quite heavy for a mirrorless camera, the strap feels very comfortable and could obviously cope with something even heavier.  The supplied circular split rings were slightly too big for the Fuifilm lugs, and had to be replaced with slightly smaller ones.  I have not downgraded my rating because of this since, after all, the strap is intended for a Leica camera.

[0.14 lb] I love it on my M11. Helps me hit critical focus with my M 11.

[Leather] FIts snugly on my camera and does what it should do, esp. for those closer focus situations. I feel it's better married to leica lens than my Voigtlander as the leica's show critical focus more distinctly.
