Product features
1. 1. A compact telephoto zoom that brings you closer to the telephoto world
Model A047 is a telephoto zoom lens compatible with Sony E-mount, which was born based on the concept of “I want you to enjoy the world of full-frame full-frame 300mm more easily.” Designed exclusively for mirrorless cameras and setting the F value on the telephoto side to F6.3, the world’s smallest and lightest telephoto zoom lens for full- frame mirrorless cameras * 1) has a length of 148 mm, a maximum diameter of φ77 mm, and a mass of 545 g. It was realized.

In addition, RXD (Rapid eXtra-silent stepping Drive), which has excellent quietness, is used for AF drive. Since it supports functions such as “in-body camera shake correction” and “eye AF” of Sony cameras, you can enjoy high-speed, high-precision telephoto shooting with confidence even if you have it in your hand.

This lens allows you to experience the compression and pulling effects of a full-scale telephoto lens more easily than ever before. It extends the range of telephoto shooting not only to landscapes, sports, railroads, and aircraft, but also to more familiar subjects such as portraits and snapshots.

* 1) For 300mm class full-size mirrorless telephoto zoom lenses. (As of August 2020. According to Tamron research)

2. 2. Designed with the highest priority on weight reduction, which demonstrates excellent optical performance and mobility
Model A047 is compact, lightweight, and has an optical design based on thorough simulation using the latest design technology in order to realize an easy-to-enjoy 300mm. As a result, we have succeeded in achieving both the overwhelming lightness of 545g, the compactness of a slim lens barrel with a maximum diameter of φ77mm, and high image quality. The lens configuration of 15 elements in 10 groups with LD (Low Dispersion) lenses arranged appropriately suppresses various aberrations such as axial chromatic aberration that are likely to occur in telephoto lenses. The 300mm lens, which is frequently used as a telephoto zoom lens, provides high resolution performance from the center to every corner of the screen. In addition, the number of lean lenses that contributes to weight reduction and the effect of Tamron’s BBAR (Broad-Band Anti-Reflection) coating, which has a reputation for anti-reflection performance, combine to make it extremely clear. Images can be obtained over the entire zoom range. Although this lens is compact and has high basic optical performance, it is possible to achieve even higher depiction performance by utilizing the “lens correction” function of Sony cameras.

Whether you are new to full-scale telephoto lenses or are looking for a compact and lightweight telephoto lens, you can enjoy shooting freely without worrying about the size and weight. This telephoto zoom lens is also recommended for those who want to reduce the weight of their luggage as much as possible when shooting with a camera equipped with in-body camera shake correction or a tripod.

In addition, a good balance can be maintained even in combination with an APS-C size E-mount camera, which is smaller than the full size, so you can enjoy shooting with a telephoto effect equivalent to approximately 450mm * 2) .

* 2) 35mm equivalent focal length when using APS-C size mirrorless interchangeable-lens camera: 105-450mm

3. 3. Equipped with stepping motor unit “RXD”
The AF drive is equipped with a sensor that detects the lens position with high accuracy and a stepping motor unit RXD optimized for AF control. Since high-speed and precise AF operation is possible, you can continue to accurately follow the subject with a lot of movement that is expected to be taken with a telephoto lens. In addition, because it is also excellent in quietness, it can be effectively used in scenes where quietness is required, such as in concert halls, or in movie shooting where the driving sound of the lens is easily recorded.

In addition, it also supports the “Direct Manual Focus (DMF)” installed in Sony cameras, allowing you to manually fine-tune the focus without switching the focus mode after focusing with AF.

4. Easy to use as a series
Model A047 has the same filter diameter of φ67mm as our full-size mirrorless lens series * 3) . If you use this series as an interchangeable lens, you can share various filters such as PL filter and ND filter and lens cap, and you can shoot more smoothly. You can also minimize the expense of stocking filters.
