Key Features & Optical Performance
Dramatic 180° Ultra-Wide Field of View: Delivers an expansive curvilinear perspective, turning standard scenes into highly stylized compositions with strong visual impact.
Advanced Hybrid Aspherical Element: Incorporates a high-precision hybrid aspherical glass element to mitigate chromatic aberrations and control spherical distortions, ensuring clean rendering and higher definition throughout the frame.
Ultra Multi-Coating (UMC): Every lens surface features a sophisticated multi-layer anti-reflective coating to maximize light transmission, effectively suppressing ghosting and flare for deeper image contrast and neutral color fidelity under tough lighting conditions.
Removable Petal Lens Hood: Unlike previous iterations with fixed hoods, the CS II edition features a completely removable hood mechanism, preventing vignetting when used on full-frame cameras in crop mode and minimizing flare when attached.
Tactile Manual Focusing: Built with a smooth, well-dampened manual focus ring and a dedicated manual aperture ring for precise, tactile setting control over your exposure and focus parameters.
