Canon R5 Announced with 8k

In the case of the R5, I think Canon has fixed some of it. External recording is acting as desired and if they can work on internal recording times as well as the C-LOG3 addition for more DR, the camera will be set. The R6 seems like a semi-fail as the heat issues can not be blamed on the huge MPX. I really hope they address this camera as it does not have a 4kLQ place to hide. I think this will impact sales so I am optimistic some paths forward will be made as it is embarrassing if anything else. The A7sIII will be available if Canon does opt to let the video folks flail. But the Sony image is kind of like your S5 AF analogy. It is better but something kind of holds me back. Potato Jet made a C300 III vs FX9 video and the first scene was a side by side with a question "pick which one is which". I picked the Sony straight away because of the yellow undertone to the image. Sure it looked nice but I just can't get used to always trying to remove greenish or yellow tones from your frame.

It will be interesting to see it unfold.
 
That's why I wrote eventually...IF they will mitigate the overheating issues in a meaningful way with a fw update, they will do it after some sales of the C70...so a loooooong way from now...that's what I was saying...

I do not share your optimism nor do I think that would be a wise business move.

The R5/R6 are already selling well. Canon will be happy to move some buyers to the higher-margin C70.

Meanwhile, Sony and Canon are executing their checkerboard product strategy. If you have Canon lenses, like canon color, need the best IBIS, need high-res stills, etc, you may settle for the R5. If you need a fully-functional video mirrorless camera, it's the A7SIII for you.

All this talk of Canon fixing the R5 reminds me of the excitement for the S5 AF. Wishful thinking. But I'd be glad to be proven wrong

This is getting interesting - it's starting to look like there may be reliable workarounds or even a magic lantern script eventually to reset the timer. I could save a lot of money over the A7SIII/new lenses by buying the R6 and using my EF lenses...and it does no-crop 4k60p with AF which is my primary goal.

Starting to consider canceling my preorder, at least to consider the options longer. Decisions decisions

You have a few weeks before the A7sIII is released. It seems a lot can happen in the mean time. I did the Magic Lantern thing with my 5DmkIII. It worked but do not want a hack or trick to be the source of my camera doing its thing. The more I watch videos from both brands the more I realize they both can work very, very well for nice video acquisition. Reading the bit about the Magic Lantern fix made me remember the disdain for Canon and why I gave up on them. And what do you know, here we are again! Definitely seems pre-programmed.

As a side note, I would not be surprised if Sony improves some things in the final release. The skin tones could maybe use some improvements imho. They seem to have this camera out there very early in the hands of users. PB & Brandon Li mention having the camera in April. The CVP tests show the R5 and the Sony in studio lighting and they are not too far apart.
 
TBH i have already soured on the R6 and returned to the A7SIII since writing that.

I looked at some more R6 footage and thought - it isn't all that. Maybe the R5 is better. I think I could certainly do the R6 job with an A7SIII, but it has more horsepower.

And also - I see a lot of postings for FS7/a7SII. That's one of the most common requests I see for shooting interviews/b-roll. So why not go that route.

And the FX9 is a good camera. If the FX6 looks good too, I'll feel like Sony is a worthwhile system to invest in if I ever want to sell my FS7 and trade up. My E-mount lenses could serve the next camera and do AF unlike on the FS7

The Brandon Li demo using the gyroscope data to stabilize footage in Catalyst was pretty amazing too
 
Magic Lantern is risky. If the camera dies for any reason it will void your warranty. The long term effects of running a very hot camera could shorten the life like over clocking a computer. Any failure past 1 year would be a total loss not to mention the risk of a failure in the middle of the job or unforeseen consequence . A client isn't going to care what camera you use. One of the most under rated features is reliability. You also need to consider the easy of use factor. Not being distracted by your equipment and being able to concentrate on the subject is of paramount importance.

This needs to be a sticky and at the top of every new piece of gear thread or “should I buy this?” thread.
 
C-Log3 will not increase DR, it’s just a different gamma curve. What you can expect from it is less compression in the highlights.

Seriously. My attitude toward these hacks is that if you have enough money to buy both the R5 AND another body that doesn't require hacks so that you can have fun experimenting while having the security of reliability covered, great. Otherwise, why would you want a workhorse camera (ie Helps pay the bills), that has no duplicate backup body, and that requires bypassing overheating time limits? We have absolutely no idea what the long term health of the camera will look like when doing this. Doing your gimbal shot during a critical shoot day for a client 1 year from now and it dies on you...you can't work that way in a professional environment unless you have that backup body already rigged up and ready to go within a couple of minutes.

Yes, it looks like it uses a timer, but there is no way that a very compact and fanless 8k body doesn't need to breathe a bit at some point in some conditions. How would you know how much it needs to breathe? There is no test other than using it in a variety of conditions over the next year or two that will give you a sense of that. Why risk that, again, unless it's a side project for fun? The image is nice, but not that nice.

I'm not completely in love with the image from my Panasonic cameras, but I keep using them because they've never let me down. I have switched over to using p4k pairs for a couple of recent projects because I prefer the image, but even then, I bring my pair of Panny cams along because I need the backup in case of issues.

Bingo. I'm laughing at all of the editors who updated to the bug and issue-ridden Catalina and are now dealing with the even more buggy and issue-ridden FCP X 10.4.8/9.
No FX9 support (Apple says to just use Catalyst!), messed up Canon CRL support (Wow, Apple, really? Your support of CRL up until this has been decent although you won't
let us select white balance and a few others but at least CRL in 10.4.6 works!)

Dealing with the R5 or R6 in a professional capacity, for most of our typical use cases, isn't a wise move.

You understand software development isn't magic, right?

Issues will appear along the way as it is a complicated universe consisting of many moving parts.

I do. And if anything, the landscape is more and more cluttered. It's more the users who have their updates set to automatic that I am questioning more than the manufacturers.
Several colleagues are incessantly whinging about how the newest of version of XYZ doesn't work anymore with this or that. Me, "When did you update?
more importantly, WHY did you update?" Them, "I don't know, I had everything set to auto update..." Me, "Oy".

I don't update anything anymore unless I hit a roadblock and have to update, I've been stung so many times over the years and experienced regret, especially on FW updates where you cannot go backwards.

There was a time, decades ago, when I installed beta versions of new software just to try the latest and greatest. Yes, I was an idiot. Maybe I'm still one, who knows, but at least not in that sense.
 

People are overreacting to the hacks. A working R5 is a $4,000 8K camera. Now, go find another 8K camera for under $50,000. OK, when BMD 12K comes out in numbers, it'll be a $10,000 12K camera but, at the moment, there's Helium/Monstro and nothing else. And, if you're afraid of overheating, take along a temp gun.

The only thing is - if you truly NEED an 8K camera, maybe you could afford RED? Or certainly UMP12K soon.

I just NEED 4K60p ATM. Does anyone NEED 8K right now? Perhaps a few do.

You can say that 8K offers performance enhancements but no-fuss reliability is another kind of performance enhancement.

That being said and speaking purely academically, I really doubt you're going to cook your R5 over time based on the temp readings on internals that numerous people have tested

Roger Cicala (from LensRentals) has taken the R5 apart and discussed heat dissipation here

We haven't had a similar teardown of the A7SIII, so can't really compare equally. But we do have Sony-provided drawings that show the A7SIII thermal management. Comparing the R5 teardown photos to those, the A7SIII has a separate graphite heat sink for the sensor, and the rear heat sink for CPU and electronics appears interconnected and with broad pathways to form a large surface area. How those are connected to the internal chassis, we don't know. See attached.

On the R5 I don't see how the heat is supposed to exit the aluminum sink. The thermal path looks very narrow -- it's just screwed into the PCB or bottom tripod mount plate. For the CPU heat sink, the thermal pad is apparently *below* the PCB. IOW no thermal pad on the CPU itself on top, but one touching the PCB below. I don't see how that would work well.

Cicala had a good point about thermal conductivity of the chassis (presumably magnesium). Thermal conductivity of Mg isn't as good as Al and far less than Cu, but it's way better than Titanium. If hypothetically you wanted to conduct heat from the internal sink to the Mg chassis, that would require a good pathway. It appears the Mg chassis has been anodized or coated somehow. Even if the Al heat sinks were screwed into that it would probably require an untreated bare surface to transfer heat well. Maybe that's what Cicala meant by the chassis having poor thermal conductivity.

We'll have a lot better basis for comparison once Lens Rentals or someone else tears down a production A7SIII.
