ARRI-mini

Interesting move from ARRI, the new Alexa mini, I suspect its to combat the one major problem with the Alexa in general…its a big heavy camera. No doubt DoP’s have been feeding back to ARRI about a smaller lighter camera with the same specs as the bigger camera for more interesting shots.

Having been working in the video business since 1988 I have amassed a great amount of knowledge of both the kit and production values over the last 30 years.
