DXOMark have tested the raw sensor output of the GH4. Raw stills have 12.8 stop dynamic range vs 11.7 stops on the 5D Mark III, illustrating just how far ahead almost everyone is on sensor performance over Canon.
All the high ISO footage from the Sony A7S so far have been highly compressed and streamed on YouTube. Here we have not one but two stages of very aggressive noise reduction being applied to the images. If you want to see it without the heavy compression removing all trace of noise, here’s a full resolution JPEG shot at ISO 12,800 from the camera courtesy of DCFever…

The Panasonic FZ1000 looks like a very handy alternative to the Sony AX100 camcorder and RX10 bridge camera. It’s also the world’s first 4K camera (25p,30p) under $1k. At this price some compromises are bound to come into play and we’ll get to those in a moment.
First let’s take in the rather lovely view… A 25-400mm Leica lens, 100Mbit/s codec for 4K, 120fps 1080p slow-mo and CineLikeD/V profiles just like the GH4.
The Sony A7S is the camera I am most looking forward to in the coming months and although it is a shame it lacks an internal 4K codec, it does promise much improved internal 1080p and 4K HDMI output. Here Yosh Enatsu has used the Blackmagic HDMI to SDI Ultra HD converter to a Hyperdeck Studio deck to record this test shoot in the dead of night.

I’ve been trying some run & gun shooting with no rig, just a gorilla pod and GH4 all handheld.
In the process I developed three image profiles for the GH4 which I’ve assigned to the mode dial on my camera.
This is the first footage to show what the GH4 is capable of with the EOSHD Cinema profile.

The new EOSHD Panasonic GH4 Shooter’s Guide is for filmmakers, photographers and all users interested in mastering video on the GH4!
The guide covers the features of the camera concisely telling you only what you need to know and nothing that you don’t.
8bit DSLR codecs get quite a lot of bashing for banding, and it is something we’re well used too… A sky or a wall taking up half the shot with only 4 or 5 shades where there should be a silky smooth gradient with thousands of tiny steps in-between darker and slightly lighter areas of the image.
However one of the first things I noticed with the Panasonic GH4 was that banding was greatly reduced and it looked like my 10bit Blackmagic footage, even though it was still an 8bit codec (internally with 4K). Why such a turn-around for an 8bit codec? It turns out the 4K mode on the GH4 holds the key to hiding this banding… yet it is something we can apply to all DSLRS…
