ASPH Optics. Edge-to-Edge Precision.
Aspherical lens elements eliminate spherical aberration and field curvature across the full image circle — delivering razor-sharp detail from center to corner, accurate color rendition, and clean cinematic rendering at every aperture. Whether wide open at F2.8 or stopped down for maximum depth, the 50mm LS ASPH renders with the consistency and character that professional productions demand.
