Regarding the old setup, it's quite natural. The lens is slightly out of focus, and the sensor is also shifted, so defocus is unavoidable here. As for the kit lens, which is of course soft, it's mostly the softness, but there is also some defocus. And so. I've seen my own photos. But I try to focus the image as much as possible; beyond that, the setup doesn't allow it. If the sensor in this photo is also shifted, then that's clear, but there is also stopping down the aperture, which sharpens the image up to a certain point.

Yeah, that area is really rich in targets! I plan to gather more data from this region and process it properly. :)
