I don't remember the last time I plugged a camera with a wire into a computer to transfer files outside of work, which is probably also why I don't understand why people are so gung-ho about USB-C charging. I'd rather not risk ruining the port or some other assembly on the camera that'll cost hundreds to replace in the case the wire gets snagged, etc.
I didn't receive my CFexpress reader yet. I don't care if the camera overheats while importing. Im just pointing out my first observations.
The R5's closer competitor isn't the A74, it's the A7R4, which has more limited video features than the R5. And if the past is any indication, I'd also agree that the Sony would be better for video... but the A74 is slotted against the R6, which doesn't overheat when using 4K24 (similar to quality of R5 HQ) with an external recorder accord to Gerald Undone's latest tests. So you have the same dichotomy in Canon that you have with Sony. The higher IQ cameras are prone to overheating due to their higher resolution sensors that require more processing. The A7S3 is optimized for 4K with a 12MP sensor, and the A74 will fall somewhere in between. The bigger limitation I see with the R5/R6 is that only Clog is available and not Clog3, which preserves more DR. That and the record limit of 29:59 are limitations in the R ecosystem that are not in Sony's ecosystem.
Today, its direct competitor is the A7R4, and its a better choice, sure. Thats why I sold my a7r4 last week and got the R5. I thought it was going to be the last camera I ever need to carry with me to do all I need, but I was wrong. Great for stills, not so great for video. I prefer 4K HQ 24fps to Sony's 8 bit. But I prefer Sony's 8bit to the LQ more that reminds me of the R. Bad 4k (in my opinion) and bad DR. Sony is better.
However, when the a74 will come out, it might become the direct competitor for the real 50/50 hybrid shooter. While the 12mp of the a7siii is a bit low for stills, I don't need 45 either. The 24 range is perfect for a hybrid shooter, I think... So if you give me an a74 with the same colours as the A7SIII, the DR of the A7III or better, and 4K 24 10 BIT 422 unlimited, I will think its a better choice than the R5 with its overheating. It will be the perfect camera for. And the perfect system, as I will also have the peace of mind that If I ever need more video specs, all I need to do is add an A7S3 body to my kit.
By the way, I love canon. I want to stick to canon. But they have really disappointed me before. And just so you know, I used to defend them until I received my R5. I was on their side. But after trying it, im just too shocked at how badly it performs in the HQ video modes. I even want to cry a little bit.
Personally, I've been burned by Sony. First with an expensive DLP TV that had issues that Sony finally acknowledged but they killed off the line so they never had to fix it, and now more recently with one of their "Tough" UHS-II card. I had predominantly used SanDisk without issue, but I was tempted by Sony's higher speeds and how many have recommended the Tough cards. But then I had 3 file failures in 2 weeks with low-level formats in between. Of course, mine wasn't in the batch that was "recalled" but it also failed shortly after the warranty expired. I've had issues with my Canon gear, but Canon has always been able to fix (some under warranty and some not) them at reasonable prices. If I had only 1 camera body a couple consumer-grade lenses, then I might "risk" Sony, but I'd consider it disposable. But not with multiple bodies with lots of lenses. I'm just glad that Canon closed the "body gap" for stills. Canon may not have "won" video, but as of now, it's video is competitive as opposed to DOA like the 5D4/original R. What other FF MILC has 8K? Will I use it? Probably not, but now I might actually start using 4K instead of 1080P, and that is an upgrade. Do I need 4K HQ? Probably not... usually my videos are of the kids performances where I leave the camera on a tripod (with the start/stop in breaks to deal with the video limit). Is 4K HQ sharper and less noisy? Yes... but I'm not cropping video and at TV viewing distances, it should be OK. Perhaps I'll pick up an external recorder down the line, and by then maybe there will be an aftermarket solution (i.e. tilta cooling fan). Or perhaps Canon will release a RF camcorder. These ARE interesting times.
I don't care about 8K and I don't need raw either.
