>>4027695you're losing sharpness in the image due to diffraction by shooting at f/16
it's also forcing you to use ISO 1600/3200 which will noticeably impact IQ too
and in others, forcing you to use a slow enough shutter speed to where I can see the camera shake
basically every one of those shots would've been much better at f5.6-f8 and ISO 100-200, with a faster shutter speed
your settings are basically just giving you the worst possible performance out of your gear
assuming you're using the canon 85mm f1.8 USM, picrel is your lenses sharpness per aperture
