As a DoP I see 4K as falling solidly into the "nice to have" camp, but also being very non-essential (at least for now, this will change with time). So I really don't mind hugely either way, to have 4K or not. There is other more important considerations to take care of first.

But maybe there is an extra point to 4K that I'm missing when viewing it solely through my DoP eyes.... and that is marketing!

Might it make it easier for the producer/director to sell afterwards if it is a "shot in 4K" film? I thought I read somewhere that there are content providers (for instance Amazon who announced they'll be filming all their created content in 4K) who have a lack of 4K content and thus could pick up indie 4K films simply as "4K fillers"? It is after all very common to read consumer articles about the lack of 4K content out there.

• 16 megapixel rear camera with an infrared autofocus feature and tricolor flash to automatically adjust luminosity based on ambient light conditions
• Optical image stabilization that reduces camera shake, especially in low light conditions
• Instantly toggle Smart and Pro modes with the flick of a switch on the phone
• Infrared auto focus feature that focuses more accurately at speeds 2x faster than normal auto focus

GH3 was too weak on the vie

wfinder and its pictures were missing something (compare to EM-1 or D800) to be pleasing out of the camera or after post processing.

This Saturday, I took advantage of one class I was orginazing for my students in Shanghai (China) to do some shots with the GH4 I was doing high speed shoot workshop (Freezing water with Flash or High Shutter speed) and the GH4 did great.

It is the first camera I am using, for that type of topic, able to take so many jpg+Raw continuous fast shots without filling up its buffer too quickly. Much better than any of my students camera (Olympus EM1, Nikon D800 and D7100, Canon 700D and 70D...).

I used an Olympus 45mm f1.8 for that series of pictures (Manual focus)

From the GH4, I like the lasting Battery (5 times more duration than the on in the EM-1), the comfortable viewfinder (size, sharpness, shape), the peaking assitance for MF and the overall ergonomy of the camera. I sold my EM-1 as I couldn't cop with its weird menu, its poor battery life and one important missing feature: A physical switch to quickly change focus mode. I get it on the GH4 at the exact right position.

The EM-1 still produce more vivd and natural color, but I also like the signature of the GH4. Smoother, but great.

Only one things is still not good enough is the Dynamic Range (or Contrat ratio) of the viewfinder which is too contrasty; highlight are too easilly overexposed in high contrast situation, which is not visually accurate and comfortable to use.

Here is a short that was shot last September that was recently finished. I did editing and some post production, it was written & directed by friend of mine.

Enjoy!
