Do you think that there is realistic chance of a software update bringing 8K oversampled 4K60p to the R5 II?
The R5C has 8K oversampled 4K60p WITH THE EXACT SAME IMAGE PROCESSOR!
There is no reason why the R5 II shouldn’t be capable of 8K oversampled 4K60p with the active cooling grip!
So this is clearly an artificial limitation from Canon unnecessarily crippling the R5 II
Could you please ask around if Canon plans to add this via a firmware update.
Even some Canon employees are confused because Canon seemingly cut this feature very recently. Even the Canon website (
https://www.canon-europe.com/pro/news/meet-eos-r1-and-eos-r5-mark-ii/ ) still says that the R5 II is capable of 8K oversampled 4K 60p („Canon EOS R5 Mark II offers 8K RAW at 60fps and 4K at up to 120p, plus 4K 60p oversampled from 8K.") which is unfortunately not true

Canon might simply not want the R5 Mark II to have this feature to leave room for another camera (market segmentation) so they artificially limit the R5 II as it‘d be „too good“ otherwise.
