The Electronic Viewfinder EVF-1
This viewfinder was specifically designed to meet the needs of professional camera operators by offering an extremely fast image display, high image quality, accurate color reproduction and a number of features inherited from our optical viewfinders, in-cluding overscan.
Fast Image Display
It is critical to the camera ope-rator that the action in the viewfinder can be seen almost at the same time as the action in front of the camera. The extremely fast image display of the EVF-1 has been made possible through the creation of a proprietary high speed connection between the view-finder and the camera, as well as a shared image processing architecture that maximizes the processing power of both camera and viewfinder.
High Image Quality
A stable, accurate and high qua-lity image is important for the camera operator. The EVF-1 image exhibits high resolution, high contrast, low distortion and an evenly illuminated viewing area. All this has been made possible through a state-of-the-art F-LCOS (Ferroelectric Liquid Crystal On Silicon) micro display with 1280 x 768 pixel resolution, a high screen refresh rate and an ARRI optical design that employs the highest quality coated glass optics. Reliable color reproduction at all tempe-ratures is assured through the auto-calibrating, temperature controlled ARRI LED light engine.
The EVF-1 has not only been developed to provide the best possible image, but is also specifically designed to fit the ergonomic needs of the operator. Even when using a matte box on a short prime lens, the compact dimensions of the finder guarantee that the eyepiece can be adjusted to a comfortable position for shoulder operation. The small, self-contained unit is easily mounted in different positions: on the side for handheld, or further back for use with a geared head.
Straightforward operation is assured through camera status visible in the viewfinder and a number of quick access buttons for often used functions such as zoom and exposure assist. The viewfinders settings, as well as basic camera settings, can be changed by the operator directly on the EVF-1.
Optical Viewfinder Features
Showing their heritage, ALEXA and the EVF-1 have been designed to provide some features that pre-viously have only been available through optical viewfinders. Most important for the operator is the fact that the cameras sensor is slightly oversized to provide an extra area around the primary image in the viewfinder. This allows lighting stands, microphones, etc. to be spotted before ruining the shot. Additionally, the size of the image in the EVF-1 has been chosen to equal that of the image in the ARRIFLEX 235s optical viewfinder.
