Sigma 20-200mm f3.5-6.3 DG Contemporary Lens for Sony E Mount

The Sigma 20-200mm f/3.5-6.3 DG Contemporary Lens is built to handle everything from expansive landscapes to fast-paced sports without the need to swap lenses, making it a true all-in-one solution. Despite its wide focal range, it remains compact and lightweight while delivering strong optical performance and reliable autofocus. Capable of reaching a 1:2 magnification ratio for close-ups and offering a maximum aperture of f/6.3 at 200mm, this lens is versatile enough to stay mounted in nearly any shooting scenario. Its solid construction ensures dependable use in a wide range of environments while keeping portability at the forefront.

Weighing just 1.2 pounds and measuring only 4.5 inches when retracted, the lens balances a travel-friendly design with a broad zoom range stretching from ultra-wide 20mm to telephoto 200mm. A focus mode switch and zoom lock provide added control, with the lock preventing unwanted lens extension while still allowing release through zoom adjustment so no shot is missed. The front element is treated with a water- and oil-repellent coating for durability outdoors, and the overall design is both dust- and splash-resistant to protect the internal optics.

The optical construction includes four aspherical elements, three Special Low Dispersion elements, and one FLD element within 18 elements arranged in 14 groups. This combination reduces aberrations and preserves clarity throughout the focal and aperture ranges. A 9-blade rounded diaphragm ensures smooth bokeh, while advanced simulation technology enhances performance in backlit situations by suppressing flare and ghosting. Autofocus is powered by Sigma?s High-response Linear Actuator system, offering quick and quiet focusing that performs well for both stills and video. Separate focusing elements also maintain accuracy across the zoom range, ensuring consistent sharpness from wide-angle to telephoto.
