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.
