Optical character
The 7Artisans 15mm F4 is a manual-focus 114-degree rectilinear ultra-wide that was sold in L-Mount alongside Sony E, Canon RF and Nikon Z versions. Its 13-element design uses two aspherical, three ED and five high-refraction elements to keep distortion close to zero and control coma, which suits architecture and astrophotography.
The all-metal barrel has a clicked aperture ring, a 10-blade diaphragm and a removable hood, and the front takes standard 77mm filters. There are no electronic contacts, and focus stops at 0.4m. The brand's UK distributor now lists it as a clearance item that is sold out.
