For an incoming project i'll need to shoot handhelded with my Cambo.
I have a very basic finder which works "ok" when i shoot straight, but I need to have a shift information.
As i can't try them all, i'd like to know what are the pro and cons of thoses : Alpa / Arca / Cambo / Horseman / Silvestri
Regarding: Distorsion / Brightness / Quality of masks / Reading of shift information / possibility to rotate the frame without rotating the finder.
Thanks a lot
ps: I already have an Iphone holder, but it doesn't work for this project.
