I use my Gaoersi 6x17 alongside a 5x4 or occasionally 10x8 camera so lack of a DOF scale is fairly inconsequential. I also now only use a 75mm lens with it, so far in the 2+ years I've had the camera focusing & DOF have never been a problem or issue despite the fact I nearly always use the camera hand-held. I already had a range-finder that I could have used with the camera but have found it unnecessary and sold it through this forum.
