Which stabilization mode was used in the video?

Here is a behind the scenes look of how RYOT used the 6S Plus 4k video for a documentary.

Canon clearly mentioned that 4k is not coming any time soon due to "Cost" issues. MM: Well, historically, I think that Canon was the first in the world to come out with a 4K product. In 2011, we had the Canon EOS 1D C, and then we had the Canon Cinema EOS C500 for professional use. For the consumer models, I think that we still need to work a little bit more on the balance between the cost and the sensor sensitivity before we can come out in the market. As you may know, Canon's main point of difficulty is to reduce costs. [Ed. note: This is interesting, in that Canon views cost competitiveness as their main point of challenge in the market. It's also interesting in that it sounds like we won't see much in the way of 4K video in their SLR lineup for a little while yet.]

This will give an idea of the video compression.

OIS is said to work with video now. I wonder if this includes 4k video.

Imaging-Resource had a good review. http://www.imaging-resource.com/news/2015/09/02/primes-people-tamron-relaunches-sp-line-two-sharp-affordable-prime-lenses "For those of us preferring (or needing) to focus manually, these new lenses are a joy to use. Tamron put a lot of effort into tuning both new SP lenses for, as they describe it, "high-grade MF operation". Both have a very long focus throw that allows for precise focus adustments, and the focus mechanism has a really great feel, as well."

I guess Panasonic and Atomos timed their release today.

Here is the UK press release. I guess some of the $99 covers the EU tax for allowing unlimited recording. http://www.amateurphotographer.co.uk/latest/photo-news/panasonic-tweaks-lumix-gh4-to-launch-gh4r-60067 "The photo/video hybrid now offers unlimited 4K recording (Cinema 4K: 4096×2160/24 fps and QFHD 4K: 3840×2160/up to 30 fps in MOV/MP4*) and V-Log L video capability."

Here are some updated specs. It looks like it supports OIS and digital stabilization with video, similar to what Panasonic provided with the FZ1000. http://translate.google.ca/translate?hl=en&sl=ja&u=http://digicame-info.com/2015/07/gx8.html&prev=search - Still camera shake correction: Dual IS (body 4-axis / lens 2-axis) - Video of the camera shake correction: HYBRID OIS + (5 axis)

If this is using the new 20mp sony 4/3 sensor then it will have much faster sensor readout and can easily support full sensor readout at 24/25p and possibly 30p with 16:9. http://www.sony.net/Products/SC-HP/IS/sensor2/products/index.html

I wonder what method of AF it would use on an E-M1 body (on-sensor PDAF or CDAF).

I'd be surprised if it has "HIGH SPEED" auto focus.

Just a slow 10x zoom.

Roger at LensRental posted test results from their copy. http://www.lensrentals.com/blog/2015/03/slr-magics-50mm-apo-hyperprime-cine-t2-1-mtf-tests

It may be closer than we realize. There was this rumor from 3 months ago that suggested something was coming at NAB. http://www.canonrumors.com/2014/12/canon-to-target-the-gh4-with-new-dslr-type-cr2/

It looks like we may finally get a AF101 replacement and it should be more than just a GH4 with different body. http://www.43rumors.com/ft4-new-af101-successor-to-be-announced-at-nab-show-has-brand-new-mft-sensor/ "I had a conversation with a Panasonic Rep here in Japan.He told me in the near future there will be an upgrade of the AF 101 camera announced. Newly designed sensor will have an immense dynamic range of up to 15 stops and 4K. Sensor will be a big surprise in unexpected ways. Not sure about the price tag though."

Now this sounds interesting. ttp://photorumors.com/2015/02/20/new-panasonic-video-and-stills-camera-to-be-announced-at-the-2015-nab-show/#more-68168

Here is detailed review of the stabilization modes in video.

This promotional video was shot handheld with some scenes done at 300mm. http://www.techradar.com/news/photography-video-capture/cameras/how-good-is-the-olympus-e-m5-mark-ii-s-5-axis-stabilization--1283807

dpreview posted a short interview with Samsung. They made an interesting comments related to sensor readout speed that would suggest it can do 4k @‌ 24p with full sensor readout. http://***URL removed***/articles/7808127857/ces-2015-samsung-interview-mirrorless-to-outsell-dslrs-in-three-years "The sensor readout is very fast - 240 frames per second. For autofocus object tracking we read at 120Hz. We can do full resolution sensor readout at 25 frames per second, and digital signal processing [with a new chip and algorithms] at 15 frames per second. "

More details have emerged. It has a native ISO of 5120 with huge DR. http://www.sonyalpharumors.com/sr4-detailed-spec-sheet-of-the-new-sony-apcs-active-pixel-color-sampling-sensor/

LX100 has a 43mm filter thread.

According to Cameralabs the 4k video involved both a crop and scale to get to 4k. Has anyone been able to confirm this? Is moire more prevalent in 4k video vs the GH4? http://www.cameralabs.com/reviews/Panasonic_Lumix_LX100/ "But bizarrely Panasonic has opted to employ a mild crop and a scale to generate the desired frame size. This means the LX100's 4k footage not only has a slightly narrower field of view to 1080 video and 16:9 stills (so instead of 24mm at the widest zoom, you're getting 26mm), but it also now suffers from moire. I feel it's an unnecessary compromise too, since a nice clean 1:1 crop would have only involved losing 4mm in the diagonal field of view. I put my disappointment to Panasonic and I got the impression the scaling along with absence of Cinelike D profiles was partly for the LX100's target audience and partly to protect the GH4, but I still think a 1:1 crop would have been better, and rather than detract from GH4 sales, I could see existing GH4 owners picking up an LX100 as a B-roll camera. Maybe flat profiles and 1:1 video crops will be offered in future third-party firmware."

I think the pricing of the Leica clone in Europe forced Panasonic to adjust their price.

It looks like Canon was focusing in a different direction for sensor design. While a stacked sensor would be great for Landscape the sensor readout speed would be way to slow for video (aka Foveon). http://www.canonrumors.com/2014/10/multilayer-sensors-are-coming-from-canon-cr2/
