This is 500% zoom on 4K images both taken using high res screenshot. (Pathttracing)
On the left the screenshot was taken from just perspective view, on the right from cinematic camera.
The blurry artifacting is from low screen percentage. I know this because if I lower screen percentage I get same blurry render out of perspective view. However while I can get sharp screenshot from perspective view by keeping screen percentage at 100%, for some reason no matter what I do cinematic camera always gives this blurry look as if it is always rendering some lower resolution.
I think this problem is also present when rendering pathtracing from Movie render queue, where resulting frames always have this soft blurry pixels.
Is there some way to force always 100% screen percentage for pathtracing?
