The trouble with the R5 you’re paying a large premium for those video features that aren’t reliable. I don’t mind the recording times as much as the glacial recovery from overheating annd even worse an hour of just stills shooting can render HQ video modes unusable as camera has already reached thermal limits. The body design is very poor in that it has woeful thermal conductivity properties and traps heat for up to 2 hours. They really do need to make a physical change rather than just rely on fw hacks. It’s a bit rich for people to now claim it’s not a video camera, when it was Canon that was pushing 8K as the headline act. Also the 4K line skipped video is poor quality and the H.265 codec I’ve heard is a nightmare to try and work with in editing. I’m sure fw will address some issues but the poor thermals are intrinsic to their body design and choice of materials. I really want to get the R5 but will dealy that purchase for at least 6 months and hope by Q1 next year soemthingnhas been done.
I disagree with most things.
This 8K sensor seems superb, it has a very fast readout for 45MP, which translates into usable 20fps silent shooting and better AF performance as well. As good as the 1DX III / R6 sensor is, this seems like a further step up, apart from doing a stacked sensor, this is as good as it is going to get in the current generation.
They have been open about developing this 8K camera since early 2019 and they have started even earlier, so it is safe to say they knew what they were doing and they made design decisions that they had to make. They would not put a product out on the market that they wouldn't feel confident about in practise. Can they tweak a little bit in software? Probably.
H.265 10-bit 4:2:2 at this point is not hardware accelerated on most devices (H.265 10-bit 4:2:0 is, which is used in other cameras), currently only supported by Apple processors like the new iPad Pro, and it works quite well on that. So it seems that's really what it needs.
Is that Canon's fault? I don't think so.
Will we see better hardware support? Apple is planning to make a big switch to their own processors soon, after that it will be definitely supported on those.
But I can't imagine others not jumping on this train and also staring to support this codec, since it can be recorded internally with a good quality/file size ratio and they can sell new products with that.
They are just thinking ahead, other camera will probably start using similar internal codecs going into next year.
It is priced just like a 5D Mark V mirrorless equivalent would be, yes there are thermal issues but there is no extra price upon that as such, only the 'normal' price increase.
All this press will have very little effect on sales. Whether people buying it for stills or video or both, they know what they are buying into.
The global situation is more relevant, but they can't control that.
