When you film outdoors – especially in the snow – it is almost impossible to judge the image on the screen of the camera. The Zacuto loupe is excellent! It has a good magnification, blocks the light and most important, comes with a flexible base plate. Simply attach the base plate to the bottom of the camera and snap the Z-Finder on the frame. I also recommend the soft padding accessory. The Z-finder may be attached to a digital viewfinder as well.
