Canon R5 new 1.3 firmware ads CLOG3, Raw light and IPB light In: Cameras Posted March 31 I've never understood Canon's logic. I once owned the 1DX2 and they never put Clog of any kind on that camera...their flagship camera. They did put it on the 5D Mark IV, but never on the 1DX2. That's about the time I switched to Sony and have been with Sony ever since. I had plans to switch back to Canon (since I still own expensive Canon lenses) with the R5 but what kept me from switching were record limits, overheating and the hard to edit codecs. I spend too much time already putting videos together and then to add transcoding to the workflow was just too much for me. I was hoping the new firmware would match the codecs of the A7SIII and A1 cameras. Their files/codecs are such a pleasure to work with. Makes editing easy.
