Panasonic Introduces New Compact Standard Prime Lens to its Full Frame
A compact, lightweight prime designed for everyday versatility, the Lumix S 40mm f2 delivers natural-looking images with beautiful bokeh -- ideal for street photography, portraits and landscapes.
Featuring a 40mm focal length, often regarded as close to the field of view of the human eye, this single focal length lens delivers a natural perspective suited to a wide range of scenes. Its bright f2 maximum aperture creates soft and beautiful bokeh for strong subject separation in portraits and helps maintain faster shutter speeds in low-light to keep clear images without pushing ISO unnecessarily.
With an overall length of approximately 40.9mm and a weight of approximately 144g, it pairs perfectly with the compact body of the Lumix S9, creating a lightweight, portable setup that's easy to carry. The lens shares a similar profile with the Lumix S 18-40mm f4.5-6.3 when collapsed and maintains the same 62mm filter diameter.
While remaining compact and lightweight, the lens features a dust- and splash-resistant design for reliability in changing weather conditions. The front lens element is coated with fluorine, making it easy to remove dirt and oil from the surface.
To meet the growing demand for video production, the lens also incorporates features such as focus breathing suppression and micro-step aperture control, enabling smooth exposure transitions and high-quality video expression.
Alongside this announcement, Panasonic is also sharing its lens development roadmap, featuring a wide-angle prime lens designed to complement the compact Lumix S9 body and a large-aperture telephoto zoom lens to further expand the L-Mount lens lineup.
With the introduction of the new 40mm lens and its continued commitment to future lens development, Panasonic continues to expand creative possibilities for both camera enthusiasts and professionals by delivering a strong balance of image quality and mobility, contributing to the growth of the interchangeable-lens camera market.
