Canon R5 Announced with 8k

Just thinking out loud - one could probably lower the internal temps somewhat by running cooled air through the dummy connections of - a USB, a micro HDMI, two 3.5mm jacks - and the largest of them all sensor/lens opening. The problem with that the sensor itself is too valuable to putz around with and other openings are very narrow. Thinking further, it might be possible for Canon itself to address the overheating issue fairly quickly by providing own cooling slots that would work with the third party accessory suppliers. Otherwise, both R5 and R6 aren't viable for the majority of moderate users.

Johnny Behiri from Cinema5D took R6 with him to Japan on a doco shoot and, by the end, he was in a Bruce Banner mode. Angry.

Hmm I feel like if you're worried about forgetting something, well...you could always forget something crucial. Camera batteries. Memory cards. What's the difference? True, it's one MORE thing to forget. But that particular example wouldn't stop me.

I feel like the better question is - could you live with dropping down to pixel-binned 4K when forced to? Then you can probably roll without fear. I think it will still overheat recording externally in about 2-3x as long

Using one of the non-HQ modes is always an alternative, but Gerald Undone just posted he couldn't record any video after being out shooting photos for an hour in 30c temps. Even if I don't forget anything (I use a pre-shoot gear checklist so it almost never happens), the fact that you can't record anything at all is concerning. I cross 30c at about 10am these days, the rest of my day is typically much warmer. I don't always want to be tied to the Ninja, its a little unwieldy when shooting in some situations. I shoot travel content as a one-man-band and my entire kit, including my drone and gimbal, often needs to fit in my Lowepro AW450 carry-on size camera backpack, so a c300 and necessary support is just not practical for what I do. Maybe this is a case of Canon's weather sealing being too good haha. I still have time to decide, but its looking more and more like a S1h type solution is needed to make this my a-cam. I absolutely love Canon's DPAF, Clog and touchscreen functionality over Sony's AF, crappy touchscreen and Slog (I use Cine2 haha), but to get 10-bit on the EOS R I've been tinkering with would require the Ninja, essentially making the R5 my photo/B-cam. If I have to go that route, the a7s3 paired with an a7r3 or r4 for stills is looking better.

So close to the unicorn hybrid cam, but its looking more and more like it was too good to be true. I think I'm still going to get it and just use it for awhile to see if it works for me. But I'm going to pre-order the a7s3 too and just pivot to whichever one does the job better. Shooting Sony means juggling lenses more often between two cameras which I loathe, but every new test is letting a little more wind out of the R5's sail for me.

I hear you loud and clear (and have those same sunset beach 8K shots in my mind too!).

So I didn't want to get into more detail about the 28-70mm before because no one cares, but I actually watch 'Christopher Frost Photography' reviews (there are many other good channels but he's just the one I found a while ago and stuck with him and his testing process) for any lens I am highly considering and I saw it there for the first time and couldn't believe it.

Around 2:20 - https://www.youtube.com/watch?v=xuBq_Z_wuDs

Anyway, it's a tough choice indeed (even though it sounds like you should be good the way you film), but at least you can cancel your preorder a few days before the Canon ships if you like what the Sony is.

That's one I saw when researching the lens, in comparison the 24-70 has virtually no breathing - I can't see any doing focus pull tests. I just did a quick test at 70mm f2.8, focused on a chair next to my desk about 2' away and then went to my stove about 20' away, the chair didn't move at all, just went nice and soft. Same in reverse, the background just melted away as the camera refocused on the chair. Did it again focusing on a windowpane a couple feet away and then a building a couple hundred feet away outside and I can't see any shift. I'd love the F/2 and that lens just has gorgeous rendering, but the shift is a little jarring, so I saved $1000 and scored a good deal on a used 24-70 on Fred Miranda.

I thought he just meant he couldn't record any HQ video?

Also, he says he thinks non-HQ is actually line-skipped!!!

Unless the tilta fan works magic, this is looking like a hard pass to me...

Ironically, Canon may end up selling fewer C series cameras by crippling their mirrorless cameras because they have undermined their own ecosystem
 
Yes, looking more and more complicated. To buy into this series one needs to forecast how long their future jobs will last. Frustrating...
 
I was concerned that power on time would factor into the mix as mirrorless cameras are kind of always on 100% or off. The external recorder times are the worst part imho. 75 minutes is decent but one has remember that might be the total time for the day. Not a good solution.
 
Yes, this is going to be very difficult to sort out. Some time needs to pass with production cameras in folks' hands to do controlled testing. A pain for reviewers but no way will video purchasers dive in until this is a known quantity.
 
The Gerald Undone tweet showing the difference on the R5 between the oversampled 4KHQ and the nonoversampled modes is pretty drastic. More and more this camera is getting tarnished pretty badly.

I think the R6 gets more oversampled rec time than the R5 and that ambient temperature matters a lot. And also probably how long the camera was on beforehand

It's plausible for Jordan but the problem for Denver is that at 1600 M elevation, radiant heat absorption of black camera body can overheat even a GH5 parked in the sun. It will get too hot to handle even if it's not switched on. It's far more significant than ambient air. Consider Lunar day versus night temperatures, +/- 200C.
 
Like I said before I wouldn't get these cameras due to the heat issues. When you work on real jobs you have enough to worry about. People were complaining about Sony A7 series lack of certain recording formats, run times, crops, etc. They must have discovered they had to put limits to avoid over heating. On a job I'd rather have a camera with less ability that doesn't unpredictably over heat or battery die etc.

There are different Sony models.

You would have to have a deep knowledge for camera history and have followed dozens of models and systems over the years from 4-5-6 different companies to understand why certain technical specifications exist and how corporations operate.

Canon may have already been planning for the future years ago.

That site has that "Yes, our Canon overlord" vibe.

As to the adapter - as I wrote earlier today, the sensor/lens opening is the easiest way to extract the heat due to its size. But it has to be done right because you don't want to damage the sensor.

From the technical point of view, it shouldn't be that difficult either. It can be powered by the camera itself via the electric contact. And the rotating fan would be on the outside of the adapter anyway.
