dgumshu: Is that a mirrorless with EVF? :-)

More competition for Nikon and Sony, oh And for the iPhone too. I wonder if they plan to release some tele photo and prime lens options.

No you view through the headlights.

LDunn1: I do like the shape of the wings on the 787, beautiful, it just looks right, in the same was as a Spitfire wing looks so pleasing, or concordes lines.

Yes, they are looking far more eagle like.

Boissez: Wow. 10-bit 4K 60p and a useful compressed RAW format as well as nifty SD-card friendly formats for ENG. All in camera. Can't ask for more.

8b 422 is all mpeg2 DTV broadcasts.

Tommi K1: Is it a true raw, or raw like in a RED?

Tommi, Red was the first video camera capable of raw and has always used compression on the un-encoded sensor data. I'd rather the workflow benefits of a little compression than the invisible improvement of uncompressed.

Doux Vide: I'm a very casual video shooter, no big needs. I currently use PowerDirector or Vegas (depending on the features I want).
Resolve seems to be a very good tool, but I fear it may be a little too complicated (not "user friendly" enough) for me...
I will give it a try an see! I may either add it to my software palette, but I doubt I will totally switch to it...

They state in that video that v14 is 10x faster and it's already very quick.

StevenE: I use Creative Cloud and it's a great suite but its also buggy and it's a never ending monthly subscription. If Davinci is stable, fast and full service, I'd switch. In fact at $300 I may try it concurrently with Premiere etc.

Reactive, yes Reslove is a bit different since it can save to a project server with the full version. Use `Export Project' instead.

Snapper2013: The music from the start was good for about 1 minute then the music gets really annoying for the rest of the video. The timelapse apart from the music was enjoyable.

dennis tennis: Apple innovations lies in squeezing the most profit. That's their genius. There's ten thousand new suckers born every minute. Praise the Lord! God Bless Apple.

Howabout, no I stuck with XP pro through those releases, never jump in until its been proven. I couldn't understand the belly aching about 8.1, just click desktop and your back to V7 as far as I could see.

RMGoodLight: Sorry to troll, but why does this news belong here on DPREVIEW?

Also some cameras can now shoot video, even 4K as well as stills and require an electric computer to process it.

Kabe Luna: Apple would benefit from the realization that these are creative tools not art objects. At the end of the day, these things need to be practical.

Please, no more innovation, just catch up and use the old box and fill it with the best off the shelf technology, how hard is it as a lot of people make hackintoshes.
Lock Jonny in the sandpit and tell him to make some new watchbands and let the engineers do what engineers do.

forpetessake: They haven't mentioned RBGW CFA which are soon to come to the next camera near you.

Years ago the Sony F828 had an RGBE sensor (emerald) giving more greens but there was issues with it.

knickerhawk: Kudos to Richard and the others who helped him put together this piece that does an excellent job of explaining a difficult topic. Would it be too much to ask for a follow-on article about the software dimension of the problem - i.e., differences in demosaicing algorithms, deconvolution and related postprocessing strategies for minimizing and repairing the unwanted effects of aliasing (and anti-aliasing)? That would be genuinely helpful.

Also, using Siemens star crops from your studio scene test shots for your examples makes sense, but there was a lost opportunity to explicate and illustrate the common "false detail" effect of aliasing by including some magnified crops from the etching of the Dutch family in the DPR studio scene.

I've often wondered about the processing power and compromises made to de-bayer realtime in camera for video capture. With the Red camera you have several quality options in post to make it play at speed when grading. To use Full de-bayer you need a good GPU or a Red Rocket card that is really a dedicated GPU. The more time it spent guessing the missing colours the better. Back in 2008 rendering Red raw using a workstation cpu would take several seconds per frame at full quality.

I doubt these can fit inside a camera yet.

TN Args: Are you using the term 'colour resolution' properly? I thought it was measured in bit depth. The ability to resolve colour accuracy.

Resolution is really about the number of pixels and bit depth determines the colour palette. Just 10bit has almost no banding with shots and grades that are prone to it.

Richard Murdey: "very few people would be happy with a filter that blurred the resolution down to 1/4 of the pixel height"

Perhaps not, but that's close to how many of the photos we look at these days are presented to us: 24-36~50? MP sensors downsampled to view on, at best, 8-10 MP screens.

I've long wondered why no one offered a "purist option" in-camera setting where each Bayer RGBG 4-pixel cell of a 24 MP sensor was mapped to a single RGB "pixel" to give a 6 MP image file. Like Pentax pixel shift mode but without the pixel shift...

Richard, Sony actually made a single RGB sensor on one of their early cine cameras, I think it was the Genesis so it's possible. It was only HD therefore only needed a 6mpx or maybe 8mpx sensor that was doable at the time with high quality.
I remember the rep at the trade show saying, `no bayer here, full RGB'. I think there was issues with Bayer and video back then and only consumer cameras were Bayer. Prior to this all pro video cams were 3 chip RGB capture but with larger sensors this became huge, required a big dichroic block and more critical physical alignment. 3 x 2/3" sensor broadcast cameras are still alive and well making 20:1 constant f1.4 zooms possible.
Good article DPR.

silentstorm: I'm wondering what does DPR mean by "true" RAW recording? Care to elaborate further? Sony seems to be the only one saying their F55 & F65 can record true 16bit RAW for video with wider than film colour gamut. Really curious to know more detail about "true" here.

Thanks.

422 also designates the amount of colour sub sampling and I was comparing Sony's 4K colour sub sampling to it. A Bayer sensor could be described as a 211 device in luminance and chroma samples.

`The previous generation of Sony CineAlta CCD-based Super 35mm cameras used linear RGB pattern'

Like Foveon RGB capture but with a one plane sensor. 3x CCD cameras also captured RGB but it was recorded in 422.

`To maintain the high resolution in green in all directions, including diagonal one, Sony proposes a new Q67 pattern for new 4K camera systems'

This looks like a 422 compromise for 4K but still more than Bayer.

Ebrahim Saadawi: Such great lenses with great prices. So bumped I can't use them on my 5DIV or anything other than the restrictive E mount.

They do state E-mount/short flange distance "enable the compact, lightweight design" so these lenses would be considerablly different if made for DSLRs, is the most likely case scenario.

Still. A bit sad. Fujinon Zooms for Still glass prices! and it's f/2.8 constant. Bummer.

Yes very sporting prices and it looks like Fuji focus, zoom and iris servos will bolt straight on. Why aren't all serious lenses calibrated in T stops, bad for marketing I guess?

Mark Turney: Well, we live in an analog universe so it's no wonder to me why digital tends to "feel" wrong. But I'm also not sure that going back to a old technology is the answer, especially considering that Kodak digitizes the film from what I understand, looping us right back to that which we seek to avoid.

Anyway .... just some food for thought 💭

This is a digital sensor but when and if it becomes a commercial reality remains to be seen. DR would only be limited by how many photons it could count over time.
