Arri Alexa SXT W

El sistema de cámara ALEXA es conocido por su excepcional rendimiento de imagen que es fácil de operar, confiable incluso en los entornos más extremos y lo suficientemente versátil para cubrir una amplia gama de requisitos de flujo de trabajo y presupuesto.

Basada en esta tecnología probada, está la ALEXA SXT W: tiene un transmisor de video incorporado que hace que la cámara sea más pequeña y liviana de lo que sería con un transmisor externo. También significa menos cables alrededor de la cámara y menos problemas asociados, ya que el fallo de los cables es, con mucho, el problema técnico más común en el conjunto. La configuración y el encendido de la cámara son más rápidos y las producciones pueden moverse más rápido.
