The Opteka 6.5mm f/2 Fisheye Lens offers an ultra-wide 190° diagonal angle of view, delivering a unique perspective with dramatic fisheye distortion. Designed for both photography and video, it creates eye-catching images and immersive footage for creative projects, filmmaking, action sports, landscapes, architecture, and content creation. Featuring an optimized optical design with 6 elements in 5 groups, including one SD (Super Low Dispersion) element, the lens helps minimize chromatic aberration while maintaining sharp image quality from close focus distances to infinity. A high-definition anti-reflective coating helps reduce flare and ghosting while enhancing contrast and color accuracy. With a minimum focusing distance of just 1.9 inches (0.05m), the lens allows for dramatic close-up compositions with exaggerated perspective effects. The 9-blade aperture diaphragm produces attractive 18-point sunstars when shooting bright light sources. Built with a durable all-metal body and mount, the Opteka 6.5mm f/2 is designed for reliable performance and precise manual operation.
