Finally a half decent video thats not on that f**king 12-35mm lens an isn't compressed as hell, much better!

Not really enjoying the moire or the 24p motion. As features go, this thing is looking amazing with wifi and all. In terms of straight up IQ, I think the stock GH2 eats this thing alive in all honesty. Until I see a real DR comparison, I've not seen one example where there might be improved DR... at least nothing in the highlights that goes beyond the capability of GH2 in a visible way. All these test videos make me really cringe... I'm far from a pro and most on this forum are far better cinematographers than I will ever be, but damn if I couldn't do something way better in just an hour or 2 with this cam.

Can't believe I'm saying this, but even the initial footage that came from the NEX5n looked far superior to what I've seen so far.

I'm just going to pretend the video with the exorbitant amount of moire was done with the 12-35mm & sharpening at the maximum setting, because that was seriously silly. Still confident that we'll see some great stuff from the GH3 soon enough!

The video above by John Twigt is much better than the previous samples from the same location, except it became more of a Magic Bullet test than GH3.

Whoever uploaded that moire ridden sample on the same shoot needs to go back to school. John's video didn't test detail and moire that well, but there were a few shots that included fine horizontal patterns, like the brick work and the metal corrugated panels that all held up quite well I thought.

I wouldn't be too fast to throw the baby out with the bathwater, just yet anyway.

While VK, Driftwood and others have given us exceptional results from the GH2, it's not 10 bit. That's a limitation of the camera, they can't do anything about it.

Here is a sample video of the kind of events that I shoot. They are all in extremely poorly lit climbing gyms that are more like caves. I was pleased with the content of the video. However, I think the GH2 has some shortcomings that I would like to remedy with a GH3 + 35-100m F2.8, + GoPro III.

The first issue occurs at 2:01 into the video(Use the link below to jump straight to it). I need to shoot wide angle and 60p with a 1/120th shutter(because of the fluorescent lighting). The only lens that I have that shoots wide with a fast enough aperture is the 14mm F2.5. However, you can see in the video that it shot with ISO 6400 @ F2.5 and the noise is just too much.

In addition my only option with the GH2 is to shoot at 720p @ 60 FPS for these slow motion shots. With the GH3 I hope to be able to shoot clean ISO 6400 in video with 1080p @ 60 FPS.

The second issue is that I sometimes need to go really wide in low light. M4/3s simply does not offer many AF m4/3s ultra wide and fast lens. The best option is the 12mmm F2.0 but that is $800 and it really isn’t ultra wide at an equivalent of 24mm in 35mm terms.

Therefore, I am going to get a GoPro III with its F2.8 lens and mount it directly to the hot shoe of the GH3. Its low light capabilities are not great but its ability to go ultra wide with a reasonably fast lens and shoot at 120 FPS should work perfectly for close up slow motion shots like the one in the link below.

Finally I need a fast telephoto zoom lens with IS for the times when I shoot sport climbing in larger gyms. I shot the video below with the 45mm F1.8 and the 2.6x and 3.9x ETC modes. The video is simply too shaky for those focal lengths.

So that will be quite an expensive kit. However, I will have everything covered from about 10mm F2.8 through 25mm F1.4 and on to 35-100mm F2.8. That is a very powerful kit when you consider how light it is and the fact that both the GH3 and the GoPro III can do wireless semi-live view to a smart phone. That will make monitoring and streaming very affective.

The moiré and aliasing in the video for the GH3 probably won’t affect me because there are not a lot of fine patterns in the climbing gyms. I can see how it could be a problem for others though.

Slashcam Germany made a small "pre"-review with the beta firmware. All in all same image quality not worse than the GH2. But with beta-firmware no sign of better dynamics and probably more moré. Better colours in low - light, but also more noise.

A lot of people are thinking that a final firmware could cure the moire/aliasing of the gh3. I think it is just plain stupid, no firmware is going to change hardwired hardware properties of the down-scaling. From what we have seen it is 99% a Sony sensor and we can expect about the same performance that the other Sony, Nikon and even Olympus dslr video. The 16 megapixel could help compared to the higher resolution 24 and 36 megapixel Sony sensor as you will have less line skipping. But it won't be as clean as gh2.

It is obvious that Panasonic has decided to outsource the sensor tech for economical or even technological reason. Sony is definitely producing the best sensor for photography nowadays and they are enlisting everyone to there exmor sensors. This must be a Sony sensor division strategy to capture the dslr market with tech and prices in volumes.

@svart

Normally it is not true, pixel binning is happening on CMOS sensor and only reduced number of data is transferred to LSI. Otherwise we'll never had any moire issues and all the videos had same look as downsized photos. But, unfortunately, bus do not have enough speed.

So it's partly hardware and partly software.. But if the sensor already downscales in hardware, then how does it read out for a full 16mp picture? Obviously there are different modes of readout then, which means that even on the sensor it's still software controlled.

I believe what we are seeing in the initial pre-production firmware of the GH3, is what Nikon and Canon, and to a lesser extent Sony, have known for a while now, that is that you can't have a truely 50/50 hybrid stills camera/ video camera without sacrificing the video section.

With the early GH series (GH-1, GH-2), I believe, the cameras where more Video-centric , maybe 60% video/ 40% stills camera. They were, in my opinion, design for video first and stills later. The moire and aliasing we are seeing seems to be typical of what we see when a dslr/slr manufacturer tries to up their "Stills" section game at the expense of the video section. Or when they use a sensor designed possibly by Sony or by a predominately stills manufacturer in their camera.

Again, this is just my opinion!

@Vitaliy_Kiselev

After the 2 x 2 pixel binning, the resulting picture is about 2.7K. Do you think it's possible to intercept that picture before it gets reduced to 1920? If so, that would be a monumental hack, turning the GH3 into a Blackmagic camera with 60P.

well, that shut everyone up :)

Well, lens correction can cause some funky side effects. As many have pointed out, most gh3 videos with moire seem to have been shot through the 12-35 f2.8, so maybe the correction algorithm for this lens isn't suitable for the gh3's new anti alias filter or the pixel bining. Reworking the algorithm could solve this.
