gh4 footage looks good indeed

any of you guys pre-ordered it with the yagh?

well this is amazing for it's size and price. If he used a tripod would have been even more impressive. consumer video technology is moving so fast lately.

this thread was a very interesting read, thanks to all who participated to the discussion

I also want to see a side by side comparison of the internal recording footage compared to the external 10bit one. Even better if they push the footage in post to compare how it holds up. But have not seen any as of now.

I own the 18-35 sigma 1.8 that I use on my red one mx, it is a beautiful video lens, so much that professionals in the industry are paying more than 3 times the lenses worth to have it modded in a cine housing. That would be the perfect choice but it does not cover full frame. Since the 35 is faster and I assume it should be a little better or to the least just as good. here is a video on a mark III, all shot wide open, looks plenty sharp to me.

boils down to 2 choices imo - want cinema housing on your lens, better suited for video, at the expense of losing autofocus for photography : samyang 35mm cine lens - want excellent price/performance, no cinema housing, with autofocus for your canon camera when taking pictures: sigma 35mm 1.4

raw mode. not an expert on this cam but from what I have heard raw yields sharper results but severely increases moire. Friend of mine who has it says he prefers to shoot in prores because of that

please not this madness again ;-) the general public does not have the technical vocabulary to describe the image issues they dislike. but they will non the less appreciate a good quality image and dislike a bad one. gh4 clear winner here. terrible raw from the bmpcc but everybody knows that now, prores is better and would have made more sense to compare from to begin with. thanks for sharing!

great news, the d800 is an amazing stills camera It's true that since affordable 4k cameras are being released at the moment this might be a much needed, yet late, update. Aside from panasonic, those affordable 4k camera don't seem to deliver yet, slow rolling shutter issues with the sonys, many issues with blackmagic... But this is a free upgrade to a superb still camera, so it is welcome any time ;-)

very interesting thank you. Can you share just 1 frame of the original 4k and the same frame downsample to 2k 10bit? Just to experiment in post to test the difference

that is good looking footage indeed

very good specs and design, again blackmagic impresses on paper as usual, I would be saving money right now if that camera was from sony, panasonic etc... but it's from blackmagic, which means they won't likely deliver nowhere near on the schedule they claim and it will most likely have a lot of issues. I'll just quote some of the comments on nofilmschool: "Personally, I’m very skeptical of anything BM puts out. My friend got the BM 4K and it’s pretty bad IMO. Yes, it’s cheap but the vertical banding, black hole sun and white pixel issues which he got all of on his tests makes it borderline not unusable in a real shoot, at least until the issues are fixed." "Agree 100%, I’ve been testing multiple 4K BMPC models, and all of them have sensor issues – some are better than others, but some are not usable in any lighting scenario." and that is after being what, 1 year late? blackmagic is all hype and they don't deliver imo. But I do very much like how they put a lot of pressure on the market and shake things up, that is awesome.

ah well nevermind then... in cf there is still room for improvement? I assume faster cf will follow as well

"Compatibility: Backwards-compatible with SDHC/SDXC supported host devices" and the card can record 4k. So now the only limitation is the output speed of the mark III itself. Wonder how high res we will get continuously now...

EDIT : apparently sd slot is limited on the mark III was not aware of that my bad, so no improvement to be expected it seems. -------------------------------------------------- Sandisk annouced their new SDHC/SDXC card : http://www.sandisk.com/products/memory-cards/sd/extremepro-sdxc-sdhc-uhs-ii/ With a write speed of up to 250mb per second. This should work with magic lantern right? Could get serious frame sizes continuously with this, around 3k to 4k maybe? I got over 2k working without any problem with my 1000x card that writes 95mb per second. Hopefully it will work :-)

the 128gb ones are known to be slow, the 64gb versions are recommended

The red dragon has out performed the mighty d800e sensor. According to dxo mark it has the best performance, beating any dslr and medium format camera. And that is at 6k ff at 82 frames per second. http://www.dxomark.com/Reviews/RED-Epic-Dragon-review-First-camera-to-break-the-100-point-DxOMark-sensor-score-barrier/Overall-score-Epic-Dragon-takes-first-place-101-points -As the new leader in this category, the prototype Epic Dragon surpasses the Phase One P65+ and P65+ HR models in color sensitivity, and it marginally exceeds the mighty Phase One IQ180 digital back in our rankings. -While every effort was made to ensure the Epic Dragon adhered to our rigid testing protocols and that the results passed all the tests we performed, it’s clear the scores reflect a significantly different approach to image acquisition. -It’s also worth noting that the Dragon’s native sensitivity is ISO 250 and measured at 104, while all other sensitivities were obtained by digital gain. -For the tests, the camera was set to full 6k resolution at 23.98 fps, 16 bit and RC 5:1 compression. -The highest color sensitivity ever measured: exceptionally low noise at the base ISO. -The headline news is, of course, that of the Dragon’s exceptionally low noise levels. The SNR (signal/noise ratio) curve shown above is simply outstanding - it’s higher than the Nikon D4’s curve for the whole of that sensor’s signal response. The shape of the response curve is interesting as well. -Close to saturation point, it shows a kind of plateau or leveling off, which indicates that the SNR is mostly limited by some pixel response non uniformity and not by the photonic noise. This noise curve, coupled with a good color response, leads to a very high color sensitivity. At the pixel level (screen mode), the color sensitivity is simply the best ever measured. We normally calculate color sensitivity using an 8-bit output sRGB colorspace. In this case, however, the 8-bit sRGB color space was not large enough to accurately represent the color sensitivity of the Epic Dragon. As a result, we had to switch to a 16-bit sRGB color space! -Conventional DSLRs benefit from Analog gain that seems to amplify read noise and fix pattern noise in a smaller way than a pure digital Gain. This explains, despite its quality, why the Epic Dragon has lower low-light performances than the top DSLRs. So for cameras, where the lighting can’t be controlled, analog gain is preferred. That’s not such a high priority with a cinema camera, but the Epic Dragon produces very clean looking files and can be used safely up to nearby ISO 3000, with an excellent image quality.

I would but I use my D800 professionally so I can't afford to risk anything with those early hacks. Really looking forward to seeing what they are capable of squeezing out of the camera though :-)

comparison video on vimeo with download option please :)

been waiting on a d800 hack for ages. it's magnificent for stills love it. hope it gets released soon

Perfect answer.

pocket comparison here for those interested

*edit removed condescending phrasing that was uncalled for it's actually very different 00:31 blown out mushy highlights on bmcc not on canon 00:58 high crop factor on bmcc 01:10 terrible shadow performance on the bmcc (if you want to see how bad it truly is watch in full screen) 1:27 global shutter on bmcc better than rolling on canon they differ in highlight performance, crop factor, shadow performance, and global shutter vs rolling shutter. Completely different.

very interesting in for workflow
