7Artisans’ new AF 40mm f/2.5 FE lens is here. It is a compact full-frame prime designed to stay small enough that you barely notice it on the camera. The Sony E-mount version weighs about 90 grams and measures roughly 63 by 40 millimetres, putting it in pancake-style territory. The lens uses a lightweight plastic exterior and a 46mm filter thread. Optically, it consists of seven elements arranged in six groups and uses a nine-blade diaphragm, a configuration that tries balancing the compact size with good image quality and reasonably smooth out-of-focus rendering.

The 40mm focal length sits between the classic 35mm and 50mm perspectives, offering a 56.1-degree field of view. Minimum focusing distance is about 0.4 meters, allowing moderately tight framing for details, food, or portraits. Autofocus is driven by an STM stepping motor, supporting continuous AF and face- and eye-detection on compatible Sony bodies, which should make it usable for both stills and basic video work.

The aperture range runs from f/2.5 to f/16. While not especially fast, f/2.5 helps keep the lens small while still offering subject separation and usable low-light performance. A clicked aperture ring provides direct control, alongside a physical AF/MF switch and a customisable function button on the barrel. The AF 40mm f/2.5 FE is available for Sony E-mount, with Nikon Z and Leica L versions planned later. Pricing is at $159.
