Because full frame is just too small, Sony are supplying a 4K video capable sensor to Leica and Pentax in the region of 40 to 50MP. According to a Leica rep at NAB the company is planning 4K video for their implementation of the sensor in the Leica S. Indeed Pentax have already announced that their 645Z will record 4K video.

A few days ago Thomas Worth of Rarevision (5DToRGB and RAWMagic) asked me for some original files from the GH4 so he could develop an experimental app he had in mind. The result is an embryonic new command-line app for the Mac, which takes 8bit 4:2:0 4K H.264 files from the GH4 and resamples them to 10bit 4:4:4 in 2K DPX format.

These images (download the original 4K file at Vimeo to get even a clue of the full performance of the camera) are rather lovely. I’m also very impressed with the 2K slow-mo at 96fps.

Sony A7S APS-C mode

One of the enigmas emerging from the A7S is whether you can shoot 4K in APS-C crop mode as well. APS-C is Super 35mm in cinema language.

APS-C crop mode would also allow the use of standard Sony E-mount / NEX lenses, Canon EF-S and Nikon DX lenses.

Sony’s information (above) implies that is the case with “both resolutions available at both full frame and APS-C size”.

I dug a little deeper to find out more…

gh4-vs-a7s

It looks like the story of 2014 is taking shape in the form of very high quality 4K on large sensor mirrorless cameras. Last year for me it was raw on the 5D Mark III which excited me the most and before that it was the Blackmagic Cinema Camera. This year is more exciting on the tech and creative front than any I can remember.

Here’s my look at how the GH4 and A7S compare in detail for 4K cinematography…
