Product details

With a bright aperture of F1.8, it maintains shutter speed in indoor and low-light conditions and ensures an immediate response that creates a blurred 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 providing excellent image quality and contrast from the center to the periphery, it offers crystal-clear, sharp image quality. The stepless focusing allows for precise control and delivers images with incredible sharpness, making it the ideal choice for indoor and night photography. The ultra-wide angle enables you to capture the creative space beyond the eye and convey an expanded sense of scale.
