A quick demonstration of what the Viltrox 56mm f/1.4 can deliver. Taken at f/1.4 ISO 100 hand-held and run through Photo Ninja with every option turned off. NX Studio delivers better and truer colours as it knows all about the Z fc, while PN hardly know anything other than the pixel dimension of the NEF. Nonetheless, the result delivered by PN is clearly "better" in terms of image clarity and micro tonality, although colours are a little off (too much red etc.). Until PN has a profile for Z fc, I have to build session profiles, or just ignore the colour inaccuracy.
Anyway, the entire frame, then 100% crop. Focus by AF on the white picket fence. It is almost unbelievable this is f/1.4 with a modestly priced lens.
