I searched both a painless viewfinder control option for ground level macros as well as a focusing aid for my mounted on the tripod MF 600mm telephoto lens, both things done the DR-6 Right Angle Viewfinder perfect. Irritating for me was at first the light weight, the processing is, however, beyond all doubt, the viewfinder image is brilliant, the viewfinder display easily readable and also the diopter adjustment adjusted not unintentionally. Whether these features justify the fourfold price compared to a similar (or is it?) No-name product, everyone likes to decide for themselves. I've been buying at least not looked back.
