I ordered 30 and 42mm and found its value is more than I spent if I only accept it is not 68 degree but 60 degree. I haven't done any field test yet but tested with my APO in the living room and it looks like parfocal, which is good. I don't have any problem using these 2 inch beasts, it's well made optically and mechnically but if you expect 68 degree of wide view than you will soon disappointed. Even though I satisfied its performance with given price range.
