Feature: 1. Easy Creation of Panoramic VR: If you want to take 360 degree panoramic photos, a fisheye lens is an essential photography equipment for panoramic photographers. The reason why you choose a fisheye lens for 360 degree panoramic shooting is mainly because it has a larger visual impact on taking a single photo, thereby reducing the number of photos that need to be spliced together in 360 degree panoramic photos. 2. F2.8 Large Aperture: Wide angle and large aperture are major advantages for capturing landscape themes. Due to starry sky photography often shooting in dark environments, the larger the aperture, the greater the advantage of the lens. In the same lighting environment, lower ISO can be used for shooting to achieve better image quality. 3. Fisheye Lens Are Also Ultra Wide Angle Lenses: During post processing, LR or PS software can be used to correct distortion through configuration files and post correction, resulting in a wider picture than ultra wide angle. 4. Wide Compatibility and 8 Dazzling Needles: : Compatible for R, RP, R5 and other models. New optical design, F2.8 large aperture and 8 blade circular aperture design present a beautiful defocusing effect. 5. Ultra Wide Angle 178 Degre Fisheye Lens: With a 178 degree ultra wide angle, 10mm F2.8 fisheye lens has a strong visual impact on the image, making it more imposing and spatial. 6. 0.17m Recent Focus: The 10mm F2.8 full frame wide angle fisheye lens has a close focus distance, allowing the photographer to stay close to the subject and present a "big head" effect. 7. More Diverse Lenses: 8 sets of 11 optical structures, 4 high refractive index glasses, and 1 ED glass, maintaining high definition image quality from the center to the edge. 8. Easy Shooting: The 10mm F2.8 full frame ultra wide angle fisheye lens weighs about 570g, is exquisite and compact, and achieves excellent imaging clarity and resolution.
