1、178 Degree Ultra Wide Fisheye Lens : With its 178 degree ultra wide angle, this fisheye lens creates visually captivating images with a strong sense of depth and space. Minimum focus distance 0.17m. 2、F8 Large Aperture: The combination of wide angle and large aperture is a major advantage for shooting landscapes. In low light conditions, the larger aperture allows for lower ISO settings and better image quality, making it ideal for astrophotography. 3、Rich Lens Elements: Featuring an optical structure of 8 groups and 11 elements, including 4 high refractive index glass and 1 ED glass, this lens maintains high image quality from the center to the edges. 4、Dazzling 8 Blade Aperture: With a new optical design, the F8 large aperture and 8 blade circular aperture create beautifully blurred bokeh effects. During post processing, fisheye lenses can be corrected for distortion using software like Adobe Lightroom or Photoshop, resulting in an even wider field of view than traditional ultra‑wide angle lenses. 5、Wide Compatibility: Compatible with L mount cameras for S1, S1R, S1H, S5, for Leica SL, SL1, SL2, and for Sigma FP, FP L. Weighing approximately 570g, this compact lens delivers excellent image clarity and resolution. 6、Effortless Panoramic VR Creation: Fisheye lenses are essential for panoramic photographers who want to capture 360 degree panoramic photos. By using a fisheye lens, which captures a wider field of view in a single photo, it reduces the number of photos required to stitch a 360 degree panorama. 1 x 10mm F2.8 Fisheye Lens  2 x Lens Caps1 x User Manual1 x Lens Box Item Type: 10mm F 2.8 Fisheye LensMaterial: Metal, Optical GlassWeight: Approx. 910g / 32.1ozFocal Length: 10mm / 0.4inAperture Blades: 8Minimum Focus Distance: 0.17m / 0.6ftSensor Size: Full FrameOptical Structure: 8 Groups 11 ElementsImage Stabilization: NoMaximum Aperture: F 2.8Minimum Aperture: F22Field of View: 178 DegreeFocus Mode: Manual FocusAperture Ring: Stepless Aperture
