8.3 Electronic Viewfinder EVF-1
The electronic viewfinder EVF-1 employs a liquid crystal on silicon
(LCOS) imaging device with a temperature-stabilized LED light source
to provide a bright, accurate view of the sensor image in all operating
conditions. Each EVF-1 is calibrated to precisely match the image on the
ALEXA's HD outputs.
The EVF-1 has a resolution of 1280x720 pixels, with 32 additional lines
of resolution above and 32 below the image to display camera status
information. The EVF-1 can also display a 10% surround view area of
the sensor to help the operator track unwanted elements before they
enter the recorded image area. Focus can be checked by temporarily
zooming into the image with a magnification factor of 2.25x. The low-
latency interface of the EVF-1 has a delay of less than 1 frame.
The EVF-1 has button controls for false color check and zoom, as well
as buttons and a jogwheel to control EVF and camera settings.
