Product details
With a bright aperture of F1.8, it maintains shutter speed in indoor and low-light conditions and provides an immediate response that creates a blur effect to highlight the subject. With minimal spherical aberration and distortion, you can capture images with incredible precision. By reducing the impact of flash and ghosting effects on your images while maintaining excellent image quality and contrast from the center to the periphery, it offers crystal-clear, sharp image quality. The continuous focusing allows for precise control and delivers images with remarkable sharpness, making it the ideal choice for indoor and night photography. The ultra-wide angle enables capturing creative space beyond the eye and conveys an expanded sense of scale.
