Tamron has adopted a dedicated design for mirrorless cameras and achieved a compact size once again by fixing the aperture at F6.3 at the telephoto end. The maximum diameter is 77mm. Measuring just 148mm (5.8 in) and weighing a mere 545g (19.2 oz), this 70-300mm F4.5-6.3 is the world’s smallest and lightest telephoto zoom lens for full-frame mirrorless cameras. Compatible with Sony’s popular E-mount cameras, it has been developed with the concept of enabling photographers to more easily experience the universe of full-scale, full-frame 300mm telephoto photography.

In addition, the AF drive system incorporates the exceptionally quiet RXD (Rapid eXtra-silent stepping Drive) stepping motor. Because this lens is compatible with Sony camera features, including in body image stabilization and Eye AF, you can enjoy comfortable, high-speed, high precision telephoto photography, even handheld.

Moisture-Resistant Construction for added protection
Seals are located at the lens mount area and other critical locations to deter infiltration of moisture and/or rain drops and afford Moisture-Resistant Construction. This feature provides an additional layer of protection when shooting outdoors under adverse weather conditions.
