Canon EOS R5 / R6 overheating discussion all in one place In: Cameras Posted July 25, 2020 14 minutes ago, currensheldon said: It is disappointing, though not a lawsuit-inducing problem. I have a shoot next week where I have a B-Cam on a car mount for the duration of the shoot while I operate the A-Cam (a C300 III). I use Canon's C-Series most often for my work and like to have a B-Cam with the same mount (EF with adapter is fine) and color and from the same manufacturer. It just makes things easy. Even if the R5 was released before the shoot, I wouldn't dare use the R5 or R6 for such a shoot because it may record for 30-minutes straight and then have to keep going (which those two cameras obviously won't do). At this point, The S1H or the GH5 are the only mirrorless cameras I would trust with such a job. When the EVA-2 comes out with an L-Mount, I'd much rather have that and the S1H as a pair than the C300 III/R5. But the S1H has such a nice image, it makes buying an $11k cinema camera not such a big deal. Wish it was a bit lighter and smaller for gimbal usage, but at least I know it's going to work. You forgot a BMPCC 4k & 6K. They won't overheat.
