I know I've posted two Philip Bloom videos in a row, but I haven't found really anything else all that interesting floating around the interwebs these last few days. Except maybe that bit of news about Canon and Microsoft sharing patents.
Personally, the only two cameras I'd buy for video right now are the Sony A7s, and the Panasonic GH4. I guess you could consider the Black Magic pocket cam as well, I'm just not that into Blackmagic. (I've edited with their shitty cards for years and the it's left a bad taste in my mouth. Not to mention the customer service sucks, and they borderline do false advertising. On there cards at least. Maybe their camera is good. My buddy has one, he enjoys shooting on a 5Dmkiii more, but the image quality of the BM is simply better. I also know people love their color correction tools. I've yet to use them.)
Ok, rant over, back to the Sony A7s. This video is awesome.
This Video Showcases The Low Light Capabilities Of The Sony A7s
Personally if I had to choose a camera. I would probably go with the Sony A7s. I know the Panasonic has insanely high bitrate (200mbps vs 50mbps) and uncompressed 4:2:2 10 bit out. But I'm just not a fan of Micro Four Thirds. It's difficult to get very shallow depth of field, and the low light performance will always be inferior. However, there is something to be said about the price.
