The adapter is exactly as in the pictures gives the impression: a crude construct of metal machines and adjustment - without fine adjustment. Very unfortunate, I find the fact that the screw (and mother at the same time) is attached to the adapter on the tripod, at the same time is also the screw for the distance from the camera. If the adapter so times on the tripod, the distance from the camera can not be adjusted.
Unfortunately my digital compact camera has a habit (as presumptive many other such devices also), when you turn the lens a little further extend as it is then necessary during operation. Here at first I was often "objective problems" which can automatically turn off the camera, because "something jammed the lens". Even the initial wide-angle mode is not suitable, since here too the edge of the eyepiece of the spotting scope (Yukon 20-50x50 WA) is shown in the picture. I have Ranzoomen what again has an adjustment of the lens length of the camera result. So reassemble everything from the tripod and adjust. Now make quick pictures before the camera to Auto. off, because when entering the lens is again extended further a tiny bit, jammed again, camera error. Toll.
A mother more on the adapter would have solved the problem. Therefore definitely point deduction.
