From the start we felt the GH4 could be the most significant camera Panasonic has released so far, and after using it for almost two weeks we believe it will be a genuine game-changer. Not only is it a superior performer for still image capture, but to offer such a wide range of video options – many of them meeting professional requirements – puts the icing on an already attractive cake and takes the camera into areas we could only dream about previously.

@jleo, I saw the shootout video on 43rumours. I don't own either of the 3 shootout cams yet (still on my GH2's), so I wanted to check what the real detail differences are in 1080p. I took a screencap and matched the levels, saturation & temperatures in Photoshop (more or less). Then applied sharpening to the Pocket & 5DIII to match the GH4 (attached).

At 1080p the differences are much smaller than people think from unprocessed (or non-matching processed) images. Sure the 4k detail is there, and you can zoom/stabilise etc. But otherwise either camera can give you a pretty similar 1080p image detail-wise imo. The bigger issue for me is the horrible moire on the Pocket (otherwise seems great).

(remember that different lenses were used, so DOF is different and not possible to exactly match sharpness in fore/background)

@Azo the GH4 is much better for stills. I also love holding the GH4 over the gh2. It feels really nice in the hands. Haven't been doing much video, but so far its really great.

From a DPReview poster:

@DirectorBob

Adobe updates CR every few weeks for the new cams that are out ... can't think of a "major" camera that was more than 16 days or so after 'release' for Adobe to get an updated ACR algo out to us. So ... could be a week more, but that should be tops. Hey, it's one of the pains of getting a new toy on first ship-date, you know? Everything in life has its ups & downs ... ;-)

Why do you always post flower examples?

Not always. Otherwise, it is usually only tolerable photos from the ones made by photo test site :-)

@Vitaliy_Kiselev Why do you always post flower examples?

I apologize if this is not the correct forum to post this question (there are so many now and so many pages - I did a search and did not find the answer). How can I open GH4 raw photo files? The latest Photoshop Camera Raw update will not open them. Let me say that this is a HUGE issue and HUGE disappointment. I bought the camera to be both a still camera and a video camera. If I cannot open raw photo files, then I can't even consider it for still work. Anyone have an answer to this issue other than having a useless still camera until, hopefully, an eventual update from Adobe?

You have to set the system frequency to 24hz in order to use C4K.

Yes, maddog15 is right. It is VBR. I haven't gotten a scene hitting 100Mbs yet so have been averaging around 80Mbs.

@olli66 45 minutes is the time or space left on the card at that moment.

I think this is right: The "math" is a ballpark estimate for reference only. With a Variable Bit Rate the camera's not always shooting at a constant 100Mbs. The time left on the card can also fluctuate some as the camera either records bright detailed scenes (makes the bit rate ramp up using more card space) or dark less detailed scenes.

Someone please correct me if I'm wrong on this one.
