17 elements in 12 groups:
– 3 aspherical lenses
– 4 Extra-Low Dispersion lenses
– 1 Ultra High Refractive Index lens
Aspherical (ASPH) lenses reduce size and weight, effectively preventing spherical and distortion aberration.
Extra-Low Dispersion (ED) lenses correct chromatic aberration rendering sharp, high-contrast images with clear colors from corner to corner.
Ultra-High Refractive Index (UHR) lens improves optical performance, reduces size and weight, and achieves uniform image quality from the center to the edges of the image.
