Is there a camera or video camera that can shoot 4k 120phdr?

What equipment can shoot 4K/ 120FPS/HDR? A7S3 could have been used, but you think it can't, because there is no standard to define what "HDR" is in the field of image acquisition. HDR is just a concept, not a proper term (except in the display field), regardless of its broad or narrow sense.

The correlation is as follows

The full name of HDR is high dynamic range. As the name implies, as long as the dynamic range is high enough, it can be called HDR. As for this "high" standard, there is no unified understanding or regulation. HLG (Mixed Logarithmic Gamma) is recognized as HDR (because it is the CCTV HDR standard).

PQ (perceptual quantizer) is also recognized as HDR (because it is a curve of HDR 10), other log modes can also be called HDR (because the coverage of log is usually larger than the above two HDR standards), and various Raw formats can also be called HDR (because Raw formats can be mapped to any curve in theory).

So in theory, a slightly professional camera and video camera can shoot HDR, which is nothing more than the difference between direct and post-mapping. As for 4K 120FPS, it is even simpler. Sony mobile phone can shoot 4K 120FPS.

To be more appropriate, I only list a few machines:

Sony Xperia 5 II (mobile phone), Sony α7s3 (micro-single), Canon EOS R5 (micro-single), Sony FX6/9 (photography/camera), Canon C70 (photography/camera), Red Crow (camera) and BMD Ursa mini/mini Pro (camera), and the rest are not recommended because of economic problems and the ease of use of the main body.
