This ultra-wide, distortion-free 9mm F2.8 lens is perfect for landscape photography. Equivalent to 13.5mm focal length with a 113° angle of view on a full-frame 35mm camera. It's manual focus, but easy to focus, and the sunstars it produces are quite beautiful. For Nikon Z mount. Please note that the listing is set up for F mount for convenience. - Model Name: LAOWA 9mm F2.8 Zero-D - Lens Cap: Included - Focal Length: 9mm - Maximum Aperture: F2.8 - Features: Ultra-wide angle, zero distortion Used a few times. It's lightweight and compact, making it a very easy-to-use lens, but I use multiple mounts and have purchased another autofocus lens, so I'm selling it to organize my equipment.
