The 7Artisans 15mm f4 features excellent optical performance, designed with 2 non-spherical, 3 low-dispersion, and 5 high-refractive-index lenses. Approximate zero chromatic aberration means you no longer have to worry about star trailing in astrophotography. Sharpness is unbeatable: With a 9-group, 13-element (including 2 non-spherical) lens structure, the center and edge quality of your photos will be equally outstanding

The 15mm F4 ultra-wide-angle lens provides a 114 field of view, capturing vast cityscapes and endless landscapes. Suitable for shooting scenery, architecture, astrophotography, indoor photography, and VLOGs.

With an approximate distortion of 0 at F4 15mm, this lens reduces the amount of post-processing required for architectural photography. The lens is also equipped with a detachable hood to effectively resist glare, and supports 77mm filters.
