Canon may have known cameras like its R5 have a tendency to overheat, and a new patent design shows that the company has created a unique external heat sink design to help keep them cool.
Kolari Vision -- a company that makes both filters and modifications for cameras -- has announced what it claims is the first commercially available after-market mod for the Canon EOS R5 that it claims will nearly double 8K recording time and cuts its overheating recovery time by a factor of three.
Some cameras are more prone to overheating than others, leading some photographers and videographers to come up with creative solutions for keeping their sensors cool. Industrial designer Eric Strebel came up with a solution that looks pretty unusual: he customized a computer heat sink so that it can be mounted to the back of a Panasonic GF7.
As DSLRs become more and more capable video capture machines, the problem of overheating becomes a more pressing one. With RAW video in particular, where the amount of data being captured is staggering, the sensor needs to be protected if you expect to keep using the camera for any extended amount of time.
Cinema cameras, like Canon's 1D C, have attacked this issue in the past by arranging the internals in such a way as to provide better cooling. But a couple of new Nikon patents take a different approach.
