Note: Due to the optical mirror shutter, Angenieux Optimo DP zoom lenses, any
Super 16 lenses, or lenses with dimensions not matching the dimensions in the
figure "Allowed lens dimensions with mirror shutter" drawing cannot be used
with the ALEXA Studio, as they would destroy the rotating mirror shutter!

15.2.3 Optical Viewfinder
The ALEXA Studio has an optical reflex viewfinder system with
interchangeable ground glasses.
It offers an exceptional viewing quality favoured by a large optical
design. Special care has been taken to avoid the unpleasant vignette
effect that could occur by moving the eye.
