Natural 40mm View, Large F2 Aperture

A 40mm focal length offers a natural perspective close to the human eye, making it easy to frame scenes with confidence. The fast F2 aperture creates soft background bokeh for strong subject separation and allows faster shutter speeds in low‑light conditions, even at twilight.
From street photography and landscapes to portraits, this lens performs reliably across a wide range of shooting scenarios, capturing not just the subject, but the atmosphere of every scene.

Beautiful Bokeh and Rich Creative Expression

Experience the impressive bokeh and rich creative expression unique to a fixed focal length lens. Create portraits and familiar scenes with soft background bokeh, or capture night scenes that render the sparkle of streetlights beautifully. One lens, many styles. With the closest focusing distance of 30cm, it is suitable for tabletop photography, from small objects and food to seasonal flowers, making it a versatile choice for everyday shooting.

Easy-to-Carry Full-Frame System

Compact, Lightweight Design

Measuring approx. 40.9mm and weighing approx. 144g, this lens is sized to match the LUMIX S9, compact enough to stay mounted and go straight into your bag. Its profile aligns with that of the collapsed 18-40mm zoom lens, and the 62mm filter size stays consistent across both. Choose the zoom when you want flexible framing, and switch to a fixed focal length lens when you want more intentional creative control. Together, they create an agile full-frame system that expands your freedom to shoot.

Two Colour to Match Your Style

Choose from two colour options, black or light silver, to match your camera body.
For Dark Silver S9 Camera, we recommend pairing with the Black S-S40.

S-S40 comes in black and silver finishes

Dust, Splash and Freeze-Resistant Design

Because this is a lens you will want to carry with you every day, it is designed to keep shooting in unpredictable environments. Its dust- and splash-resistant construction helps you capture fleeting moments, while allowing you to shoot in temperatures as low as -10°C. The fluorine coating applied to the front lens makes it easy to remove oil-based dirt that sticks to it.

High Resolution and Excellent Rendering Performance

LUMIX S 40mm F2 Lens Construction

The optimise configuration has 7 elements in 6 groups, including 3 ASPH lenses to effectively suppress spherical aberration and ensure superb resolution, despite its compact, lightweight design.

Excellent Operability for Comfortable Shooting

Customisable Focus Ring

The focus ring can also be used as a control ring, allowing you to assign key functions such as Crop Zoom* for zoom-like control even with a fixed focal length lens.

*Compatible with the DC-S1M2/S1M2ES/S1RM2/S5M2/S5M2X/S9 (As of April 2026). Applicable firmware versions: S1RM2 Ver.1.2 or later, S5M2 Ver.3.4 or later, S5M2X Ver.2.4 or later, S9 Ver.1.6 or later.

Focus Button (Fn Button)

The focus button on the lens barrel lets you lock focus while pressed for precise control. It can also be customised as an Fn button, allowing quick access to your preferred settings and a more intuitive shooting experience.

Direction of Ring Rotation

You can change the rotation direction of the focus ring to match your preferred operating style.*

*Compatible with the DC-S1RM2, DC-S1M2 and DC-S1M2ES. Please update the DC-S1RM2 to firmware version 1.2.

Non-Linear Mode

The focus ring supports both linear and non-linear modes. In non-linear mode, the amount of focus shift varies depending on how fast you turn the ring, allowing for quick and flexible adjustments.

Linear Mode

In linear mode, focus shifts at a consistent, user-defined rate, providing precise, mechanical-feel control that is especially useful for reliable and accurate focusing during video shooting.

Other Features

An inner focusing system driven by a stepping motor delivers fast, precise, and quiet autofocus. With AF control at up to 240 fps when working with the camera body, it enables fast focusing and smoothly tracks moving subjects across a wide range of photo and video shooting situations.

Advanced optical design and an optimised internal barrel structure effectively suppress focus breathing. In high-contrast scenes, micro-step aperture control enables smooth F-stop transitions, preventing sudden exposure changes.

Consideration for The Environment and Green Initiatives

LUMIX is taking steps to become more eco-conscious. We have reduced the number of packaging components by 33%, and the use of plastic materials by 85% compared to the previous model. Furthermore, to reduce environmental impact, we have adopted corrugated cardboard cushioning materials in our packaging.
