7Artisans unveils range of low cost, fast lenses for mirrorless cameras

Chinese optical manufacturer 7Artisans has introduced a collection of four lenses that are intended to provide low-cost alternatives to branded optics. The lenses are all designed for mirrorless cameras, and the company intermittently provides mounts for Sony E, MFT, Fujifilm X and Canon EOS M users, as well as one lens for Leica M cameras.

The lenses are all manual focus, feature a copper core with an aluminum exterior and some of them come in a choice of black or silver finish. There isn’t much information on the company website but the Amazon sales pages reveal some of their specification.

25mm f/1.8 | Sony E/Fujifilm X/MFT | $70

This lens was designed for APS-C and Micro Four Thirds sensors, and boasts an aperture range of f/1.8-16. It uses seven elements in five groups, has 12 iris blades and offers a 46mm filter thread.

35mm f/2 | Sony E/Fujifilm X/Canon EOS M | $156

A lens capable of covering a full frame sensor, this 35mm f/2 uses a 10-bladed iris and has a minimum aperture of f/16. It is constructed with seven elements arranged in five groups and offers a 43mm filter thread.

50mm f/1.1 | Leica M | $369

Designed for the Leica M family, this standard focal length uses 12 iris blades to form its click-less f/1.1- f/16 aperture range. The company says it has used a Sonnar design and high-refractive index glass to optimize the lens for use at the widest apertures. The lens has seven elements arranged in six groups.

The current version isn’t compatible with the Leica M4 and M4A, but models from September onward will be.

7.5mm f/2.8 | Sony E/Fujifilm X/MFT | $139

This is a fisheye lens that the company claims offers a maximum angle of view of 180°. It has 11 elements that are arranged in eight groups, and the 12-bladed iris closes to f/22.
