Compact telephoto zoom

Designed specifically for mirrorless cameras, and with an F6.3 aperture at the telephoto end, the 70-300mm F4.5-6.3 is the world’s smallest and lightest full-frame mirrorless telephoto zoom lens, coming in at a mere 5.9” long with a maximum diameter of 77mm and weighing just 20.5oz. Easier than ever before, photographers can now experience the compression effects and limited depth-of-field unique to a real telephoto lens. This lens is also ideal for users who want to reduce the weight of their luggage or lighten their load on nature walks. In addition to landscapes and sports, users can enjoy telephoto shooting for a broad array of subjects like portraits, birds, and casual snaps.

Superior optical performance and supreme lightweight portability

Based on thorough simulations utilizing the latest design technologies, the optical design of the 70-300mm F4.5-6.3 successfully balances its compact size and high image quality. The optical construction includes 15 elements in 10 groups, with an LD (Low Dispersion) lens element precisely arranged to suppress axial chromatic and other aberrations that are likely to occur with telephoto zoom lenses. At 300mm, a commonly used telephoto focal length, the design delivers excellent resolution from edge-to-edge. The new zoom creates extremely crisp and clear images throughout the entire zoom range due to TAMRON’s BBAR Coating, which is world-renowned for its anti-reflection performance.

The RXD (Rapid eXtra-silent stepping Drive) stepping motor unit is exceptionally quiet

The AF drive incorporates a sensor that accurately detects the position of the lens while the RXD motor unit delivers optimized AF control. This achieves very fast and accurate autofocus operation and allows users to maintain tack-sharp focus on continuously moving subjects often shot with telephoto zoom lenses. Thanks to the exceedingly quiet AF, the lens can be used discreetly in concert halls and other situations that require low noise levels, as well as for video shooting.

Dedicated TAMRON Lens Utility software
