Some extra details have surfaced around 7Artisans’ upcoming LITE autofocus lens lineup, which includes three APS-C primes, 25mm f/1.8, 35mm f/1.8, and 50mm f/1.8, all designed for Sony E and Fujifilm X mounts. As the name suggests, compact size and low weight seem to be the main focus. All three lenses share a very similar physical design, measuring around 67mm in diameter and 51mm in length, and weighing between 178 and 183 grams depending on the focal length.

Optically, the designs stay fairly straightforward. The 25mm uses 8 elements in 5 groups, the 35mm goes with 7 elements in 6 groups, and the 50mm has 6 elements in 5 groups. 7Artisans mentions the use of high-refractive-index glass to help keep aberrations in check without making the lenses bigger or heavier. All three share a 9-blade aperture, an f/1.8 to f/16 range, and the APS-C-only coverage. Close-focus distances scale with focal length, 0.25m for the 25mm, 0.35m for the 35mm, and 0.55m for the 50mm.

Autofocus is built in, with manual focus available as well, and there is a USB-C port on each lens for firmware updates. They also keep things consistent with 58mm filter threads and metal barrels across the lineup. Field of view ranges from 58.3° on the 25mm down to 31.4° on the 50mm. Pricing has not yet been announced.
