After some searching and found in the Internet, I bought only two Sun-Sniper belts (for the use with a backpack - awesome - and the - also highly recommended, if you are traveling only with the camera).
Both straps are screwed into the tripod socket of the camera and thus have a major drawback. If I want to switch between the two and, exactly, wants to use the tripod, I can every time the annoying Prodzedur, unscrew, pure screw else, check whether fixed seat, back out screws next purely screws, check whether tight fit through.
That had to be better somehow,
The solution for my Nikon D5300 is the MENGS DC 38Q now as follows:
1) First, a universal Arca Swiss compatible recording must be found, which is screwed into the camera in the tripod socket and never needs to be removed again. I have taken, since low and still built very solid. It also has left and right a flap to accommodate a hand strap.
2.) Now, the DC-38Q comes into play. This is suitable for Arca Swiss systems and is screwed to the Sun sniper camera straps. Also unique and no longer needs to be solved. I had first bought the DC-38 (without Q), and then later, for the second belt, the Q variant discovered. I find the Q even better, since pages are tabs at all three. Both terminals are manufactured very accurately and with value and function perfectly.
Since then, my photo-walks are a delight. Even day trips with the camera on the side without any problems. Since nothing is loose or interfere and change of belt to stand and back again in a matter of seconds.
