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.

IBC is a convention for the moving image industry that is second only to NAB. It's an event that's amazing in its size and scope. We haven't been around long enough to have our own official awards, so here's my own ideosyncratic top three from this year's show, in reverse order

There's no doubt that Sony's pretty pleased about the results of their F65's role in Oblivion. And well they might be: the internet is bursting with plaudits for the look and style of the film

You wouldn't expect any film with Tom Cruise in it to be short on production values and Oblivion proves the point. Shot in shimmering 4K with Sony's F65, it relies less overtly on computer-generated special effects than other sci-fi blockbusters

Can you make a feature film with an iPhone? Well, "yes" is the answer if you don't mind a slightly fuzzy-looking picture on a big screen, and if you sit far enough away, but you can certainly get a cinematic "look" if you use cinema-type techniques when you make your film, and some software to give your work its finishing touches.

With Sony's F55 shaping up to be such a good device, it's reasonable to wonder about the future role of Sony's flagship camera, the F65.  We spoke to Richard Lewis, Product Specialist for Cimenatography at Sony Europe, to get some definitive answers

A British film, Belle, is the first in the UK to be shot in true 4k with Sony's F65 camera

Rolling Shutter is a type of distortion that affects cameras across the price spectrum. The more you know about it, the better you can deal with it

You may think we're hammering it a bit with the Sony F65, what with our piece on Belle, and with our forthcoming article on what differentiates the F65 from the F55, but let's be clear about this: we are actually at the point where you can make better films with video than you ever could with celluloid - and that's worth a significant amount of coverage

Here's the first film we've seen showing London from the air filmed in genuine 4K with a Sony F65
