Expanding Your Creative Horizons from Ultra-Wide 20mm — A Seamless Flow to the Natural 40mm View 

The 20-40mm F2.8 features a unique focal range starting at 20mm. At the 20mm ultra wide-angle end, it provides a sense of depth and scale that conventional standard zoom lenses simply cannot match, capturing the full essence of a landscape. At the same time, the range up to 40mm is ideal for everyday snapshots and portraits. When used with APS-C mirrorless cameras, it provides a full-frame equivalent of 30-60mm — offering the flexibility to handle any scene without changing lens. 

Mobility and High-Speed, High-Precision AF — The Perfect Support for Video and Vlogging 

The compact, lightweight design ensures exceptional handling, offering a significant advantage for video shooting. The 20-40mm F2.8 remains perfectly balanced even when mounted on camera grips or compact gimbals, making it ideal for handheld shooting and vlogging. Additionally, the 20mm focal length lets you capture the broader background while maintaining a comfortable distance for selfies. The AF drive features the VXD (Voice-coil eXtreme-torque Drive) linear motor focus mechanism. This high-speed, high-precision system tracks subjects smoothly and accurately from MOD (Minimum Object Distance) to infinity, reliably following moving subjects during video shooting. Furthermore, the quietness of the linear motor allows for inconspicuous shooting in noise-sensitive environments, whether for stills or video.

High Image Quality in a Compact Body — Powered by Specialized Lens Elements 

The 20-40mm F2.8 is packed with TAMRON’s proprietary optical technologies, delivering imaging performance that defies its compact size. The optical construction features 12 elements in 11 groups. By generously incorporating specialized lens elements, including four LD (Low Dispersion), along with two GM (Glass Molded Aspherical) lens elements, the 20-40mm F2.8 achieves outstanding optical performance. A key highlight is the beautiful, soft bokeh that only a fast F2.8 aperture can provide. Furthermore, the BBAR-G2 (Broad-Band Anti-Reflection Generation 2) Coating effectively suppresses ghosting and flare, ensuring clear and crisp images with excellent contrast. 

Wide Macro Shooting with an MOD of 0.17m (6.7in) — Discover the Power of Close-Ups 

With an MOD of just 0.17m (6.7in) and a maximum magnification ratio of 1:3.8 at the 20mm wide end, the 20-40mm F2.8 delivers impressive wide macro photography. By getting remarkably close to your subject, you can capture it in stunning detail while still including the expansive background. This allows for powerful, creative expression, emphasizing the unique sense of perspective and depth only wide-angle shooting can provide.
