Panasonic LUMIX S 20mm f/2.5 Lens
Ultra-Compact Full-Frame Wide-Angle Prime – Bright f/2.5 Maximum Aperture, Rapid & Near-Silent Autofocus Motor, Customizable Lens Function Button & Focus/Control Ring, Circular 7-Blade Aperture Diaphragm for Smooth Background Bokeh, Weather-Sealed Splash, Dust, and Freeze-Proof Construction (Down to -14°F / -10°C), Protective Fluorine Front Element Coating, Standard 62mm Front Filter Thread, Native L-Mount (Excellent Condition)
The Panasonic LUMIX S 20mm f/2.5 is an ultra-compact, featherweight wide-angle prime lens engineered specifically for full-frame L-mount mirrorless camera systems. Designed for documentary filmmakers, street photographers, travel vloggers, and landscape artists seeking maximum optical resolution with minimum bulk, this lens measures just 1.6 inches in length and weighs a mere 0.31 lb (approx. 140 g). Despite its pocket-sized footprint, it delivers edge-to-edge full-frame sharpness and excels in challenging lighting conditions thanks to its bright f/2.5 maximum aperture, enabling faster shutter speeds and lower ISO settings during handheld interior and night shoots.
Engineered with a responsive internal focusing drive, the LUMIX S 20mm f/2.5 provides quick, smooth, and virtually silent autofocus performance optimized for both high-resolution still photography and cinematic video capture. The ultra-wide 20mm perspective offers an expansive, natural field of view ideal for architectural framing, interior real estate, streetscapes, and environmental portraits with generous context. Creative control is streamlined through a customizable lens function button and tactile control ring, allowing direct assignment of critical parameters such as Crop Zoom. Built to withstand demanding outdoor conditions, the lens features comprehensive splash, dust, and freeze-proof sealing rated down to -14°F (-10°C), backed by a protective fluorine front coating that repels moisture, grease, and fingerprints from the 62mm front element.
