When shooting macro, the sharpness range is radically reduced, and accurate focusing is very important. In true macro photography, you can focus manually, but you must position the lens very precisely beforehand. With fixed machines, repositioning is very difficult, so we recommend using Dörr MS macro rails. The rail can be mounted on a stably set stand, the stand head, which can be slid in place, so the required distance can be set very precisely. The rail is scaled so the position can be reproduced later. The MS-160 rail is 16 cm long and has an adjustment range of 10 cm. Tripod thread is available as a standard 1/4 "camera mounting screw 2 1/4". Can be installed both lengthwise and crosswise. By placing it crosswise, you can place another device (eg action camera, microphone, etc.) in addition to the camera.
