Unfortunately, one does not come out in bright sunlight without a viewfinder and I'll have to keep him. The lenses are of good quality and there is "a clear view" through!
The case does not make very stable impression and I am concerned that the part is broken, for example during a fall or accidental rough handling. This can of course also be a false impression, because nowadays there are very resistant Kunsstoffe. We'll see!
The viewfinder is aligned with the 17mm lens and the area is indicated by a frame in the viewfinder. Since the entire field of view of the viewfinder is a little larger, it corresponds very closely to the 14mm lens. I can therefore be used for both Objekive: Full range = 14mm; Within the frame = 17mm
In other focal lengths, the corresponding areas one has to think or off. That is less than optimal.
Otherwise, you can only see through the viewfinder and that's not very much!
There is no communication between the viewfinder and the camera. So it can not be focused or zoomed. No information such as aperture, shutter, spirit level, or the like are displayed.
Conclusion: Simple part with good optical properties at a very high price. Whether the housing breaks fast, will never show hopefully.
