Feature: 1. Ultra Wide 178° Fisheye Lens: With a wide angle of 178 degrees, it delivers visually stunning and immersive images, adding a sense of grandeur and spaciousness to your photos. The closest focusing distance of 0.17m, the fisheye lens allows photographers to get close to the subject, resulting in a unique big head effect on the subject. 2. F2.8 Large Aperture: As astrophotography often takes place in dark environments, a larger aperture offers even greater advantages, allowing for lower ISO settings and better image quality in the same lighting conditions. 3. Superior Lens Construction: With an 8 group 11 element optical structure, including 4 high refractive index glass elements and 1 ED glass element, it ensures high definition image quality from the center to the edges of the frame. 4. 8 Dazzling Aperture Blades: The new optical design, along with the F2.8 large aperture and 8‑rounded aperture blades, creates beautiful bokeh effects. Compatible with for Nikon Z mount cameras Z6 Z7 and Z50. 5. Easy Panoramic VR Creation: A fisheye lens is essential for photographers who want to catch 360 degree panoramic photos. Its wide field of view reduces the number of photos required for stitching, making panoramic photography easier. 6. Ultra Wide Angle Lens: In post processing, fisheye images can be corrected using software like LR or PS. By applying lens profiles and making adjustments, the distortion can be corrected, resulting in an even wider field of view than traditional ultra wide angle lenses.
