TTArtisan’s New AF 40mm f/2 Prime Lens

credits: TTArtisan

TTArtisan just released the AF 40mm f/2, a compact prime lens for full-frame Sony E and Nikon Z cameras, with an L-mount version expected soon. The optical design uses nine elements in six groups, including two high-index elements, one extra-low-dispersion element, and an aspherical lens to control chromatic aberrations and maintain sharpness. The aperture runs from f/2 to f/16 and is made up of seven blades, with a clicked aperture ring for manual control. This combination makes the 40mm focal length a versatile choice, slightly wider than a 50mm, but still offering a natural perspective.

Autofocus is handled by a stepping motor with a lead screw drive, giving smooth and quiet operation that should suit both stills and video. The lens can focus as close as 0.4 meters (about 16 inches), which is useful for tighter framing without switching to a macro lens. The 40mm f/2 also accepts 52mm front filters and while the lens doesn’t have optical image stabilisation, it’s small and light enough to pair well with bodies that have in-body stabilisation.

Physically, the AF 40mm f/2 is built from aluminium, weighs 167 grams (5.9 ounces) and measures 44mm in length with a 61mm diameter. The lens doesn’t come with weather sealing however. Pricing for the TTArtisan AF 40mm f/2 is at $168. A closer look at the new lens will follow in this week’s Sunday magazine issue ;)
