It’s nice to see the R5 getting all these features added. Three years later Canon finally admits that the whole overheating and recording limits where all simply firmware cripples.
Now Canon, can we add opengate mode to the $6K Canon R3? And while you are at it, how about enabling the extra two audio channel when using the Tascam audio adapter?
Let’s just be done with the crippling of these cameras once and for all.
Here we go again, sigh...
One of the reasons why Canon sells more cameras than anyone else, is that they are masters of market segmentation. They know exactly how much to include, and how much not to include, to make a product sell well. Thus they leave certain features out of cheaper or current models, and save them for higher-end or future models. That's just sound business practice. Would you prefer that they sold less cameras, became less profitable, and ended up in Pentaxland?
Another possibility that you may not have considered, is that all cameras are under constant development (even after release) and that manufacturers have to launch cameras earlier than they would prefer, in order to keep up with, or stay ahead of, competing brands. Nikon, Sony, Fujifilm etc all add functionality and fix bugs via firmware updates, but rather strangely, when Canon do it, you and a few others get moaning and groaning.
It's quite possible that Canon believed that R5 shooters wouldn't want/need to shoot 8k for half an hour, and that they decided it was better to limit it, rather than have the camera overheat (which damages sensors and increases noise). At a later date, and under pressure from a tiny but vociferous minority of folk, they may then have decided to invest more time and money in developing firmware that could control the overheating - I doubt very much if it was just a case of altering a timer or a thermostat.
