Canon R5 Announced with 8k

I didn't catch the thread, but the original URSA had major cooling and the image was/is the cleanest I've ever seen still up to this point.*

*When the sensor is receiving light (as it's obviously not a low-light camera with a native ISO of 400).

... The ice box joke someone made the other day was somewhat of a true comment. If companies made stills cameras with liquid/refrigeration cooling 5-10lbs heavier (they never would), we'd see unparalleled results and offerings.

Does B&H stock camera/beer carrying cases? (see, now I add to my own joke ... well, I claim it anyway)

As to cooling, there's likely to be a myriad of solutions, similar to what was done on A6300 or C500. The more a manufacturer cooperates, the more elegant they would be. Even a sealed body can be cooled from the outside, if there are any open metal membranes that conduct heat.
 
Not like this is a secret, but my GH5 has overheated and shut down too, recording 2nd camera from a tripod in the sun, at a wedding ceremony. There was a 2nd shooter and his camera also a GH5 shut down at the same event. In fact mine may have shut down twice, I vaguely recall seeing a message come across the screen that it was overheating.
 
At another wedding, I set up a 2nd GH5s on a tripod waiting for the wedding party to arrive at the dinner. I set the camera to autofocus on two entertainers that were singing jazz standards. The camera kept the subjects in focus but the cocktail lights in the background were pulsing, the lens breathing was so distracting I had to used secondaries in post to blur the background. This was a Pana-Leica Nocticron 42.5 f1.2, one of the best lenses in the m4/3 arsenal. Whatever the camera used, lens breathing is forever a concern with auto-focus, for me.
 
But Panasonic doesn't specialize in AF so there is no lens that could ever possibly help you until the corporation makes changes.

(Unless you meant whatever the camera company.)

OMG I just edited an interview shot on an A7RIII in autofocus. Not sure of the lens, probably a Sony 24-70. Medium shot, some headroom down to his waist.

The guy is gesturing with his hands and the focus must have been grabbing them because the frame pulsed as he moved them. It was much more noticeable at the edges of frame than on him, like slight zooming in and out.

Luckily, tripod-mode stabilization in FCPX took care of it in a snap at the expense of cropping in a bit.

But cooooome on! His hands are only moving back and forth less than a foot and he's a good distance from the camera. How much does this damn lens breathe?

Yipes never happened with my GH5 gh4 gh2 or S1. How hot was it? What format were you shooting?

I was shooting 4k 24p, but he was shooting 1080p 24p. We put white towels over the cameras thereafter. It was hot, into the low 90's probably, but in the direct sun.
 
That is very lame on the part of the cameras, as hot as it sounds. I think I try to keep my cameras shaded until the last second under those circumstances, but maybe I've just gotten lucky.

Maybe we should be spritzing our cameras? I'm only half-joking. They're weather-sealed and the evaporation would probably work wonders

This ^ +1
 
a7RIII didn't have AI yet. AF is mediocre.

Nevertheless if it was set on wide (default), it will try to focus whatever is closest to the lens which it did exactly what it was supposed to.

If it had eye-AF from 2019, it wouldn't budge. Nothing. Locked on.

^ An interesting idea actually.^ Maybe not a spritz but damp terry cloth. The white dry towel might be enough. There are no vents to block. In Colorado at 5,200 feet, thin air transfers heat less efficiently.

Yeah the self-shooter was a fine art photographer and didn't know how to do it properly. Nevertheless, if the damn lens didn't breathe like that...

Yeah a white towel is probably the way to go. My Lumix cameras have been so solid but I'm glad to know more about the risky situations
 
I'm surprised it was still usable for you...bad AF ruins productions.

But better than nothing, I assume.

Maybe someone will make a cooling/fan cage for the R5...just watch your fingers.

External cooling will still need some access to the inside of the camera.

Then again, that SSD attachment for C200 had the battery door removed/faked and R5 will move a zillion more units than C200. So someone will probably get his screwdriver ready and go to work soon enough.

PS. R5 is naturally #1 with the bullet on the B&H sales charts. R6 is #2. Cue Casey Kasem for the rest.

Not better than MF in this case :)

Yeah it was usable. FCP corrected the scaling and I could afford to lose a bit of the edges. There was enough DOF that he looked in focus regardless of where the focal plane was
