>>4322528My idea is to plot the sharpness across different focal lengths and apertures and then see which ones get close enough and use those when possible.
There are other tricks too, in case that's not satisfactory enough.
Different output formats differ in sharpness, i.e. 1080p is sharper than 1080i as cameras apply a low pass filter to reduce field shimmer. I can also try 1440i/1440p and 720p.
Additionally, cameras have detail adjustment settings, that when turned down actually start to soften the image beyond what the camera actually captures. All without having to change the output format. If we go the other way and increase the detail added, it's possible to make it bold enough that it will become visually more dominant than the fine detail we usually notice for sharpness, this could help to bring the sharpness look more uniform across different cameras.
