Pricing & Availability

Optics & Construction
At the core is a 7-element, 6-group optical design that includes 3 aspherical lenses, which helps reduce aberrations across the frame. The focal length is 40mm with a diagonal angle of view of 57° — positioned between standard wide and normal focal lengths on full-frame L-Mount cameras.
The maximum aperture is F2, with a minimum of F22. The aperture diaphragm uses 7 rounded blades in a circular configuration, which influences the shape of out-of-focus highlights in the background.
The lens has no optical image stabilization built in. Filter thread diameter is φ62mm, and the maximum diameter of the barrel is φ69.4mm.
Autofocus & Video Performance
The LUMIX S 40mm F2 (S-S40) uses fast, precise, and silent autofocus designed for both still photography and video recording. On the video side, focus breathing suppression keeps the field of view consistent when focus shifts between subjects — a common requirement in controlled video productions.
Micro-step aperture control enables smooth, gradual exposure changes during video recording without abrupt shifts in background rendering.
Close Focus & Crop Zoom
The closest focusing distance is 0.30m (0.98ft), with a maximum magnification of 0.17×. This makes the lens suitable for tabletop setups, food, and other detail-oriented shots at short distances.
Crop Zoom functionality extends the effective telephoto reach up to 2× the base focal length while maintaining image quality — useful when additional reach is needed without switching lenses.
Controls & Build
A customizable control ring is built into the barrel for direct access to aperture, focus, or other assigned functions depending on the camera body. A dedicated focus button provides additional control during manual or override focusing.
The lens carries a dust- and splash-resistant design. Panasonic notes this does not guarantee protection against direct contact with dust or water. The recommended operating temperature range is -10°C to 40°C (14°F to 104°F).
