ARRI ALEXA EVF-1 Electronic Viewfinder

The ARRI ALEXA EVF-1 Electronic Viewfinder is a film-style, low latency (≤ frame delay), color electronic viewfinder with a 1280 x 784 F-LCOS micro display and ARRI LED illumination, both temperature controlled.

Accurate Image Display

It is critical to the camera operator that the image in the viewfinder reflects the action in front of the camera as close to live as possible. 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 quality image is important for the camera operator. The EVF-1 image exhibits high resolution, high contrast, low distortion, and an evenly illuminated viewing area. The EVF-1 includes 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, plus an ARRI optical design which employs the highest quality coated glass optics.

Reliable color reproduction at all temperatures is assured through the auto-calibrating, temperature controlled ARRI LED light engine.

Ergonomic Design

The EVF-1 has not only provides the best possible image, it is also designed to fit the ergonomic needs of the user. Even when using a mattebox on a short prime lens, the compact dimensions of this finder almost always guarantee the eyepiece can be adjusted to a comfortable position for shoulder operation.

This 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 viewfinder’s 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 provide some features only available previously through optical viewfinders. Most important for the operator is the fact that the camera's 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 235’s optical viewfinder.
