Description — 7artisans 15mm f/4
The 7artisans Photoelectric 15mm T4 is a manual focus, wide-angle prime lens designed for full-frame mirrorless camera systems. Its T4 maximum aperture provides consistent and measurable light transmission, a feature commonly valued in video production environments. The lens is offered in five mount configurations — Sony E, Canon RF, Nikon Z, L-Mount, and Micro Four Thirds — giving it broad compatibility across today's leading mirrorless platforms.
A 77mm filter thread makes it straightforward to use with standard filter systems, from circular polarizers to neutral density filters. Weighing 536g, the lens is solidly built without being unwieldy. No image stabilization is included, and autofocus is not supported — this is a fully manual focus lens intended for shooters who are comfortable working with manual focus techniques. Whether used for landscape, architectural, or wide-angle video work, this lens brings a consistent T4 light path to whichever full-frame mirrorless system it is mounted on.
