My conclusion - yes, there is a difference.
+ Setting the focus is child's play with the Minox. When Bresser one has quite an effort.
+ The short range is much greater when Minox (+ The picture is clearer when Minox and the viewing area is larger. When Bresser there were reflections that I did not have the Minox.
At the end I have made a quick decision and reserve the Minox despite higher price. It feels significantly higher quality.
I am not a professional and therefore is my review my subjective judgment.
