Camera Support 31
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.
Connect the viewfinder to the camera using the viewfinder mounting bracket.
NOTICE
Do not point the viewfinder into direct sunlight, very bright light sources, or high-
energy light sources (e. g. laser beams)! This may cause permanent damage to the
viewfinder display and optical elements. If possible, cover the eyepiece when not in
use to prevent any damage.
