All that about less megapixels = better in lowlight is mostly a pure myth when it comes to modern digital cameras. And has been disproven countless of times. There are numerous new cameras with more pixels than the supposedly those "lowlight monster" low pixel count cameras with equal or better lowlight capabilities. And low resolution images displayed on a modern high resolution display will most often not look better.I've mentioned it before, but I'd really rather have the R5C sensor use less megapixels and be better in lowlight than have unlimited 8k. For shooting video, I find better light sensitivity to be a much more useful feature than more resolution.
A common belief in the camera world is that lower resolution cameras – and larger pixels – perform better in low light. In this video we illustrate why you should question that bit of conventional wisdom.
