The Tamron 70-300mm f/4.5-6.3 Di III RXD Lens for Sony E is designed with a versatile telephoto zoom range and a compact structure, making it an excellent choice for full-frame Sony E-mount mirrorless cameras. This lens covers a valuable spectrum from short to long telephoto and measures only 5.8 inches in length, with a maximum diameter of 3 inches, weighing a mere 1.2 pounds. It is engineered to provide exceptional optical performance with aberration correction, ensuring high-quality images. The RXD stepping motor unit from Tamron enables rapid, precise, and silent operation, fully utilizing in-camera capabilities such as Sony's Fast Hybrid AF and Eye AF functions. The 70-300mm f/4.5-6.3 lens is a highly functional telephoto zoom option, suitable for a wide array of photography styles, including sports, wildlife, portraits, and more.
Outstanding Optical Performance
The optical design of the 70-300mm f/4.5-6.3 zoom lens has been meticulously refined through comprehensive simulations employing cutting-edge technologies. This lens comprises 15 elements organized into 10 groups, incorporating a well-considered arrangement of Low Dispersion (LD) elements. TAMRON has successfully minimized excess weight while maintaining exceptional image quality in the 70-300mm f/4.5-6.3 model. Notably, aberrations, including axial chromatic aberration commonly found in telephoto lenses, have been effectively addressed. The 300mm focal length, frequently utilized in telephoto zoom applications, delivers outstanding high-resolution performance from the center to the edges of the image. Additionally, the lens is distinguished by its remarkable bokeh, which beautifully highlights subjects against a softly blurred background. To mitigate ghosting and flare, the lens features BBAR (Broad-Band Anti-Reflection) Coating, recognized for its superior anti-reflective properties. Furthermore, the integration of lens correction capabilities within cameras allows users to benefit from enhanced performance and functionality.
High Performance Autofocus
The autofocus mechanism in the 70-300mm f/4.5-6.3 lens is equipped with an RXD motor unit designed to maintain focus on dynamic subjects. The RXD technology employs an actuator to meticulously regulate the motor's rotational angle, enabling direct control of the focusing lens without the need for a reduction gear. A highly accurate sensor detects the lens position, facilitating rapid and precise autofocus, which is particularly advantageous for capturing continuously moving subjects or for video recording. Furthermore, the lens features a focusing system that operates smoothly and quietly, allowing photographers to work in serene environments without the distraction of drive noise.
