TTArtisan has announced the AF 40mm F2, a ‘normal’ focal-length prime for full-frame Sony E and Nikon Z mount cameras. (An L-mount version is “coming soon” according to an Instagram post from the company.) It’s made to be fast, compact and affordable despite having features like a clicking aperture ring and all-metal construction.
The lens is made of nine elements in six groups, with two high-index elements, one extra-low-dispersion element and one aspherical lens. It has seven aperture blades, and can focus on objects as close as 0.4m (15.7″).
Autofocus is handled by a stepping motor. The lens can fit 52mm filters, and weighs 167g (5.9oz), despite being made out of aluminium. It also comes with a metal, petal-shaped lens hood.
The lens is available now from TTArtisan’s website and only costs $168, which is a very approachable price. If you’ve never shot with a ‘normal’ focal length lens before (as in, a lens that offers a similar perspective to human vision: neither zoomed in nor out.), it could be an affordable way to try it out.
