Hi! I am a bit confused: The R5 manual states, that HDR-PQ movie recording is only possible in full HD. But with my R5 it seems to work also in 4k… On the same page in the advanced user guide (page 333 of 919), there are also a lot of strange problems mentioned, which I was not able to observe when testing the HDR-PQ mode. For example, it is also mentioned that every movie frame is a product of two individual frames… sounds very strange and if true it would make the HDR-PQ practically useless (what shutter speed to use then? What about the 180 degree rule, when two pictures are combined to one?) It‘s a bit like if the manual was written for a different camera. What do you think about that?
