Hi!
I would very much like to build myself a full frame "director's viewfinder" - the kind that is able to take the actual lenses on it. Basically, a very simple housing which has the lens mount in front, the full frame glass at the back, and some kind of eyepiece or prism which would present the image normally (right side up). Like the image attached.
Admittedly, I want to create a director's viewfinder for cinema use, with a PL mount in front. Digital camera sensors are getting larger and larger (they will eventually become 36x24mm in a few years) - but the principle remains just the same.
I can't use DSLR's because some cinema lenses have large back elements which interfere with the mirror (especially on the wide side). I can't use regular cinema director's viewfinders because all of them can only take small viewing screens, far from the full frame size.
So, basically, I would just want a simple housing with a prism/eye piece for proper viewing.
For photography, is there a full frame lens viewer made by any company? Does such a unit exist in some form or another? I could definitely take something and try to adapt it to my specific needs... Let me know if there is any chance to find a lens finder for the full frame 36x24 format.
Thanks so much! I appreciate it!
Mike
