ALEXAs Novel Lens/Sensor Mount
To further improve the legendary stability of the ARRI lens mount, ALEXA is equipped with a novel lens and sensor mount design. The stainless steel lens mount is attached to a stainless steel tube, which itself is attached to the sensor mount. The whole unit is then attached to the camera body. By creating a fixed link between lens and sensor, a super stable flange focal depth is ensured - even if strong mechanical influences are applied to the lens mount, such as when a heavy zoom lens is not properly supported. Using stainless steel ensures minimum material expansion or contraction during temperature changes.
