>>4072046I'd be curious which Nikon camera you're shooting on, because if it's like a D850, I might attribute that difference more so to resolution than the lens itself.
It's hard to compare test-chart / mtf table wise across brands and cameras, but Lenstip has both tested on 24mp cameras (D3x vs X-T2), and the 35mm f2 is significantly better, which matches my own experiences with both lenses.
The Fuji 33 f1.4 would be marginally sharper, but not sure it'd be enough of a difference alone, and I honestly still use my 35 f2 more often due to the size.
The Venus Optics APO is probably the sharpest x-mount lens at that focal length, but much bigger and manual focus. I can't speak to the Viltrox, but seems the Tokina equivalent is worse.
Top is 33 f1.4, bot is 35 f2 for reference.
