Nikon Plena: Features a more intricate optical design with additional elements, including Extra-Low Dispersion (ED), Aspherical, and Short-Wavelength Refractive (SR) glass for superior aberration correction and sharpness. Its advanced coatings (Meso Amorphous, ARNEO, Nano Crystal) are top-tier, minimizing flare and ghosting.
-
Viltrox LAB Z: Employs fewer elements but includes 2 ED and 2 Super ED elements for chromatic aberration control. It lacks aspherical elements, avoiding onion-ring bokeh but potentially sacrificing some edge sharpness. The multilayer nano coating is effective but less advanced than Nikon’s.
