The world's smallest and lightest* telephoto zoom lens for Sony E-mount.The 70-300mm F/4.5-6.3 Di III RXD (Model A047) is a telephoto zoom lens for Sony E-mount designed exclusively for mirrorless cameras, created to allow more people to enjoy the world of telephoto photography. Despite its wide telephoto range, this lens boasts the world's smallest and lightest dimensions, measuring just 148mm in length, 77mm in maximum diameter, and weighing just 545g. With a focus on image quality, the lens uses special glass elements optimally positioned to suppress chromatic aberration and other aberrations. Enjoy high-resolution images and the beautiful bokeh characteristic of telephoto lenses. The AF drive is equipped with a quiet, high-speed, and precise RXD (Rapid eXtra-silent stepping Drive) stepping motor unit. It features a simple weather-resistant construction and supports various camera functions, including Eye AF. Its versatile applications include landscapes, sports, trains, and airplanes. It also demonstrates its capabilities in situations where you want to enjoy easy, handheld shooting, such as portraits, snapshots, and sports events. Furthermore, the unique "compression" and "pushing-in" effects of telephoto lenses can be utilized to expand the scope of expression. The joy of telephoto photography lies in pulling the subject from the depths of the viewfinder. This lens will open up a new world for you. *For 300mm-class telephoto zoom lenses for full-frame mirrorless cameras. (As of August 2020, according to Tamron) Enjoy the world of telephoto with a mirrorless lens. Tamron focused on making this lens as compact and lightweight as possible, ensuring that you can easily enjoy the world of telephoto photography with this 300mm telephoto lens. Redefining traditional telephoto lenses, the lens measures just 148mm long, 77mm in diameter, and weighs just 545g, allowing you to fully immerse yourself in photography without worrying about size or weight. This lens is recommended not only for those attempting serious telephoto photography for the first time, but also for those who want to reduce their luggage weight when using a camera with in-body image stabilization or a tripod. It also maintains excellent balance when paired with an APS-C E-mount camera, allowing you to enjoy an even greater telephoto effect equivalent to approximately 450mm. Lightweight Design and Superior Optical Performance: The Model A047 utilizes the latest design technology and comprehensive simulation-based optical design. Prioritizing compactness and lightweight design, the lens barrel is slim and extremely lightweight, thanks to an f/6.3 aperture on the telephoto end. To further reduce weight, Tamron is using a specially treated, high-strength Al-Mg alloy for the mount, a first for a full-frame mirrorless camera. While maintaining sufficient strength, the lens achieves a weight reduction of approximately 68% compared to conventional mounts. The lens construction features 15 elements in 10 groups, with LD (Low Dispersion) lens elements strategically positioned. This minimalist lens configuration achieves both weight reduction and high image quality. Various aberrations, including axial chromatic aberration, which is common in telephoto lenses, are effectively suppressed. The 300mm focal length, which is frequently used as a telephoto zoom, delivers high resolution performance from the center to the edges of the frame. Another notable feature of this lens is its beautiful bokeh. The soft, beautiful bokeh accentuates the subject. Tamron's BBAR (Broad-Band Anti-Reflection) coating, renowned for its anti-reflection properties, is used to suppress ghosting and flare. In addition, by utilizing the lens correction function built into Sony cameras, you can enjoy even higher image quality.
High-performance AFAF that won't miss a shutter opportunity The drive is equipped with Sony's proprietary stepping motor unit RXD. RXD is an actuator that precisely controls the motor's rotation angle, allowing it to drive the focus lens directly without using a reduction gear. In addition, by combining this with a sensor that detects lens position with high precision, high-speed and precise AF is possible. Not only does it accurately capture moving subjects, but it also demonstrates its capabilities in video shooting. It is also extremely quiet, making it ideal for indoor shooting and other situations where drive noise is a concern. [Accessories] - Round hood - Lens cap ■ Specifications ■
