Panasonic’s New Lumix S 40mm f/2 Lens

Panasonic has announced the Lumix S 40mm f/2, a compact full-frame prime that looks like it is designed to sit somewhere between a standard and a wide-angle lens. At 40mm, it offers a slightly wider field of view than a typical 50mm, which tends to give a more natural perspective without feeling too tight. The lens is also pretty small, coming in at 144 grams and 40.9mm in length.

From a technical standpoint, the lens uses a 7-element, 6-group optical design, including three aspherical elements, which are typically there to help control distortion and keep the lens compact. The aperture ranges from f/2 to f/22, with a 7-blade diaphragm, and interestingly, there is no dedicated lens hood mount. Panasonic says flare and ghosting are controlled well enough through coatings and optical design that a hood is not really necessary. The lens is also dust and splash resistant and rated to operate down to -10°C, which is pretty standard for this class.

Despite the size, Panasonic has still included a few physical controls, like an AF/MF switch and a focus button, and the focus ring can be customised. On the video side, the lens is designed to minimise focus breathing and uses micro-step aperture control for smoother exposure changes. Panasonic also updated its roadmap alongside the announcement, mentioning a future wide-angle prime in the 18–24mm range and a large-aperture telephoto zoom somewhere between 50mm and 200mm. The Lumix S 40mm f/2 will be available in L-mount for $399.99 and is expected to start shipping in early June 2026. It will come in both silver and black.
