Explore the realm of creative photography with the AstrHori 12mm F/2.8 Ultra-Wide Angle Fisheye Lens, a manual focus masterpiece designed for L mount cameras. Compatible with a variety of brands including Panasonic, Sigma, Lumix, and Leica, this lens is a versatile addition to any photographer's collection. Its robust aluminium exterior protects the lens from the elements, while the wide f/2.8 aperture allows for excellent low-light performance and a pleasing bokeh effect. The ultra-wide 12mm focal length is perfect for capturing expansive landscapes and architectural shots. I used it to shoot the starry sky in the uploaded photos.
