No matter what I do, I can't get my Nikon Z6 II to capture a sharp photo.
Pinpoint AF, tripod, shutter delay, changing apertures, whatever. Even tethering and going completely hands off. Doesn't matter what I do or how I do it, everything always inevitably looks like shit down at the 1:1 pixel level. There's always a soft blur. Not a single point in the frame is ever truly sharp.

This is a problem because I got this thing with the intent to digitize a bunch of stuff including some pretty big originals (too big to fit in a flatbed scanner) where I want to keep fine detail with 1:1 framing, no zooming in for separate "detail" shots. I set a goal for the ability to frame something 19x13 and get a sharp quality 300 DPI, but this isn't cutting it. At all. I don't know if it's my lens (NIKKOR Z 50mm f/1.8) or if it's my sensor not having enough resolution. Maybe the AA filter is ruining my fine details? or maybe advertised resolution itself is a scam when behind a bayer sensor?

I only care about such fine details in situations where the camera will be mounted and capturing still subjects.
Would a camera without an AA filter do better?
Should I get a 45MP Nikon or a 61MP Sony?
Would pixel shift likely solve all my problems?


Image 1/2
f/2.0 - blurry
f/4.0 - sharpest center point
f/16 - deepest DOF, softened by diffraction
Took shots at all aperture ranges and f/4 has the sharpest mid point but even that is never crisp.
