Now I found one at Op / tech whose (different) I also belts for VF-use DSLR. The strap was attached to the QD Sucherkamera et voilà: the strap is the little camera really the "cream of the crop"! They will not slip from the shoulder to wound the neck does not press the pad even after a long time, the belt moves flexibly to the camera loops, can also be quite abgeklipst by small clips with 2 handles and also can be easily wrap around the wrist to carry the camera by the hand. There is also a separate wrist strap that attaches to one of the two side clips to remove the riser. Again, impressed the systematics of OpTech.
Chapeau!
