Popular though the Arri Alexa is, some people have been deterred from recording the Raw output by the requirement for the camera to be tethered to an outboard recorder which sometimes cost as much to rent as the camera itself! RedShark contributor Freya reports
As we saw in my previous article on sensor technology, we can now build sensors with enormous numbers attached to them - if not trivially, at least reliably. Given that current 4K sensors are more than adequate to replace 35mm film in terms of sheer resolution, we need to be careful about turning this into a numbers game.
Hidden under the surface, there are some very big changes happening with the big manufacturers
The new ALEXA XST is a technological tour-de-force that uses ARRI's classic sensor. How does it get 4K from this less-than-4K imager? And what are the advantages of this approach?
Here's another chance to read this great article by Phil Rhodes on why cameras need global shutters. Cheaper, cinematic cameras come with a cost - they tend to have Rolling Shutters, which means that rapid movement can be skewed. The ability to buy cameras with global shutters at all price points can't come soon enough, according to Phil Rhodes
