I have had two zf41 repros, one from russia, one from sarco. More than likely they are both from the same source. The optics are good. If your eye isn't in the right place, the image is not sharp. Once you line up the image pops into clear focus. Here's the problem, look thru the scope and turn the elevation knob, on both my scopes, as you raise or lower the elevation, you can see the reticle move from side to side in the tube. So you will have to adjust the windage with every move, this is a royal pain in the ass with the german mounts.
I also looked at the 6x model at sarco, and when it was assembled, the magnifying lens was placed in such a way that it also magnified the reticle so much so that it most likely would have been a good eight inches wide at 50 or 100 yards.
If you plan to zero it at one distance and keep it that way, you might be happy with it. I ended up changing it out with a weaver k4
