This Viewfinder evaluates each camera has no viewfinder on to the multiple! The motive is to look well and perfectly controllable to assess also the final image well. Especially outdoors and in close-up a madman advantage. As described in a Rezesion, in some camera models, the orange cord screw (s) be disruptive, because eventually a knob of the camera can be out of reach of any. So it was with my compact camera. Because I use this viewfinder anyway for this device, I moved this Schnelleinstellschrauben against very flat Phillips screws. (See photo) Thus, this problem is solved.
Producer side I would like to see:
1. In addition to the orange screw 2p. flat screws, 2. a shorter rail as an option for compact cameras (trotzden with tripod socket) 3. adjustment vertically downwards Advanced models by a few millimeters; may otherwise be short of small cameras.
Following these improvements, I would "real" awarded 5 points.
