Canon R5 Announced with 8k

I've been shooting on Canon since the beginning, so obviously there is something there that feels like "home". I think the main thing to recognise is that there is obviously something that resonates with you and the footage you've seen from ML canons. Apart from the things you like, there are probably some things that prevents you from going all in on that solution.

And so the story goes.
 
That is all undeniably true.

I suppose I was wondering if, from a technical standpoint, more lush color is captured from lower dynamic range formats. I rounded on the idea because ML RAW has very limited dynamic range. As does transparency film (relative to print film), which is also noted for rich color. Some people like the F35 color, which has less DR than Alexa. Alexa is known for having a bit muted and mellow color.

I thought there is probably a connection between luma and chroma dynamic range. And that sampling a higher dynamic range at a given bit depth must yield a less precise gradient. No?
 
Looks like the latest Adobe Premiere update supposedly confirms that the R5 will record 8K in Cinema Raw Light and not something else: https://nofilmschool.com/adobe-mistakenly-confirms-canon-eos-r5-feature

So, do we think it would be 2Gbps at 8K 10-bit 30p or 4Gbps at 12-bit? Based on other camera codec implementations? Either way, it looks like CFexpress maxes out around 8Gbps minimum sustained write speeds

Personally I'd want 12-bit. But 4Gbps is daunting
 
Gosh, Canon is really aiming for people's jaws hitting the ground if their first pro mirrorless body shoots 8k RAW on down without a crop. Lets hope this is true. I am already resigned to get one or two of these and this would seal the deal.
 
Launch of R5 is getting closer!

I'm guessing it will be 8K 10bit Canon Raw Lite with 32ms readout.

The 8K 10bit file is OK with me. The longer readout, as has been mentioned in relation to some of the 1Dx mk3 modes, is more of a "hmm". You'll be able to make a lot of pretty 'portraiture style' videos without wobble, but it will be limiting in other situations.

I'll reserve judgement until its launched and tested.
 
12-bit would be preferable to 10-bit.

32ms is too slow for me. You can even get weird looking motion in someone walking or turning their head (not wobble per se).

If we're lucky, the RS will be on par with 1DXmk3 60p because it's 8K 10-bit. If we're lucky, it's fast enough to do 8k 12-bit but they just wanted to limit the bitrate.

It would be really really really cool if it could do HFR 6k and 4k RAW with a crop. But I won't hold my breath.
 
Did any of you have a 5D MKII? That Jello was horrific. I could never buy another camera with anything near that level of rolling shutter again no matter how impressive the specs.
 
It gives one pause for both R5 and 1DXmk3. Tho now I remember someone (Andree?) saying the 1Dxmk3 was only slow in 5.5k up to 30p. I think that perhaps every other mode has acceptable RS speed. But yes, that could doom 8K RAW on the R5.

Yup. Among others.... =)

What I'm saying is basically: Canon has put some cards on the table. We know some stuff that is actually looking really good on paper. It's official and undisputed. But what I find interesting is that so many are willing to take what we know and then fill in the blanks with a 'best case' fantasy.

I've been shooting Canon for many years and I will very likely continue to do so. I am not in the camp that thinks Canon's lair is a dark, moist cave, deep under the earth's surface where flames and fire spring from cracks in the jagged stone while minions with tails and pitchforks make lenses and cameras.

But I think it's prudent to think about what it means to request 8K full frame raw in a non-flagship body. I don't mean to steal the R5's thunder. It will be a capable camera. Perhaps my next one. There are simply things about it that we don't know yet, but the dots will connect at the end. For now, I'm placing technology/performance that I know exists as placeholders in the blanks. I'm not assuming that everything that Canon HASN'T talked about continue to set market leading benchmarks.

As we've seen in the 1Dx mk3—that IS a flagship camera—that has 10MP less to read out, there are restrictions to the various modes (AF, rolling shutter...).

The R5 will launch and live up to everything Canon has already confirmed. But there are still many things left unsaid that can make it problematic for discerning shooters.

All in all though, for someone like me that tends to be pretty pragmatic, it looks like a great camera, if a bit small.

The 1Dx mk3 has 16ms when shooting 50/60 fps in raw, so it's not strictly a technical limitation that way.

I would bet good money they're doing a 14-bit readout in 5.5k 30p and down sampling to store it in 12-bit.

The pixel throughput of 5.5k video dimensions at 30fps is close to that of full frame still photo capture at 20fps.

They probably thought the readout speed was adequate and you would get an IQ boost with the higher bit depth conversion. It would be such an easy engineering fix to read it at 12-bit if the Gods of Canon can be reached and reasoned with.
 
Sometimes ADC bit depth matters a lot for dynamic range, sometimes it doesn't. Dpreview often checks this:
On the GH5s, 14-bit mode gives you around half a stop more than 12-bit mode: link
On the a9, there's basically no DR difference between the 12-bit and the 14-bit modes: link
but those are cameras that don't have huge DR to begin with...
On the a7R II, 14-bit gives you between one and two stops more DR than 12-bit mode (I'd say it's very close to two stops): link

If the R5 is using 12-bit mode for raw video, I think it will be alright: once downsampled to a common resolution, it will have better DR than my current p4k. If it uses a 14-bit ADC read mode, it may or may not be absolutely awesome and a clear game changer: it depends on actual performance, not the spec. If it's going to a 10-bit ADC mode, it will be bad and I'll lose all my interest on this camera.
 
That Sony interview sounds really bad to me: they are aiming to match the specs of the S1H (4k 60fps 422 10-bit internal, still working on raw which is probably external), and they're coming out one year later, when both Sigma and Canon are doing internal 4k+ RAW on a full frame sensor with AF, and BM has already worked out the workflow kinks and got lots of people used to it.

Better have some impressive stuff because "Everything is new" and "Supreme" may just underline that they're missing the mark.
 
It depends on the price point. S1H for $2,500? And a nearly perfect auto focus? And a huge lens selection? It'll sell like hotcakes.
 
Yeah I totally disagree with the naysayers.

The S1H (and basically every full-frame camera prior to the 1DXmk3 and C500mk2) can only do 4K 60fps in APS-C crop. So if you want to switch between 24 and 60fps FF...you can't.

The S1H also has no phase-detect AF. These are the reasons I sold my S1: Phase-Detect AF and no-crop 4K60p. I only bought it because I needed a low-light monster immediately. Otherwise I would have held off for a camera without those limitations.

BM: no good AF or full-frame.

The A7SIII is coming out right on time - alongside the R5/R6, its only true competitors.

Sigma doesn't really have good autofocus. Fuji doesn't have full-frame.

Plus some folks are heavily invested in E-mount glass. Maybe others have already invested in other systems. But I've got almost all EF glass and my loyalty is up for grabs. I predict being happy with either an R5 or an A7SIII. And considering that I have an FS7, I'll probably get an A7SIII. Lacking internal RAW may hurt its sales relative to the R5, but it won't doom the camera.

And I say all this as someone who generally dislikes Sony cameras. But this is my honest take.
 
They will definitely have zero trouble selling it.

But the alpha symbol they use is lowercase so that capitalization has to go, lol.
