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.
If you're one of the people who's preordered a Blackmagic Cinema Camera, unless you're very lucky, you will probably have noticed that you don't actually have one yet. RedShark, in common with the rest of the world’s media, is eagerly awaiting the arrival of a camera to put through its paces.
