I needed a comfortable strap for my heavy Rolleiflex. It has something around 1.25kg in its basic protective case, and that's a weight you don't want to carry with a narrow strap. This K&F strap makes carrying the Rolleiflex very comfortable affair. Also, thanks to nylon woven endings, you don't have to attach the strap into all kinds of weird strap mounts on cameras, even if they don't support steel rings or triangles, which is exactly the case with Rolleiflex — the original leather strap that broke a long time ago was being attached via some clever system into two moon-shaped hooks, where one can't easily attach any kind of normal ring or triangle. The pocket on the strap is another awesome feature for all people like me — you can put there either small Rolleiflex sun shade, or two 120 rollfilms if squeeze them tight inside. Or anything similar to that, like a filter or so. Another great feature is the fact that the strap can be detached with normal buckles, not the "quick" ones, as I wouldn't trust the quick buckles with heavy camera. And again, for medium format cameras this is super useful, because often you use them on tripod or just in your hand, holding from the bottom, and then strap is unnecessary. Overall this is an awesome strap for heavier gear, or if you appreciate the special features such as the pocket or buckles. It is not the most beautiful one, looks very modern and "plastic", but the features and comfort outweigh that easily.
