Yes, they did have the right. They even specified the time limits. Fix the overheating issue? What issue? Switch to the A7 Mark IV? You don't think it will overheat when it shoots FF 8k or FF 4KHQ (downsampled 8k). Will it even shoot 8k? If not, then why not keep the R5 if it will not overheat in 4k? Just how many minutes of 8k do you typically shoot, and onto what size cards?They didn't have the right to advertise 4KHQ with that kind of performance.
