Compact telephoto zoom lens for full-size mirrorless SLR cameras that combines unparalleled compactness and high image quality

- A compact telephoto zoom lens that brings the world of telephoto close at hand
This Sony E-mount compatible telephoto zoom lens was created based on the concept of "making the world of full-size full-frame 300mm telephoto lenses easier to enjoy. Designed exclusively for mirrorless cameras and with an aperture of F6.3 on the telephoto side, the lens is the world's smallest and lightest full-frame telephoto zoom lens for mirrorless cameras*, with a length of 148mm, a maximum diameter of 77mm, and a weight of 545g.
The RXD (Rapid eXtra-silent stepping Drive) is used for the AF drive, which is extremely quiet. The camera is compatible with Sony camera functions such as "in-body image stabilization" and "pupil AF," allowing users to enjoy high-speed, high-precision telephoto shooting with confidence even when handheld.
The compression and pull effects of a full-fledged telephoto can be experienced with unprecedented ease, expanding the scope of telephoto photography to include not only landscapes, sports, trains, and aircraft, but also more familiar subjects such as portraits and snapshots.

- Lightweight design that prioritizes superior optical performance and mobility
Optical design based on thorough simulation using the latest design technology was implemented to make the 300mm lens compact, lightweight, and easy to enjoy. As a result, we succeeded in achieving both compactness and high image quality with an overwhelmingly light weight of 545g and a slim lens barrel with a maximum diameter of ø77mm. 15 elements in 10 groups with an appropriate arrangement of LD (Low Dispersion) lenses minimize chromatic aberration on axis, which is often observed in telephoto lenses, and other aberrations. The lens construction of 15 elements in 10 groups with an appropriate arrangement of LD (Low Dispersion) lenses suppresses chromatic aberration on axis and other aberrations that often occur in telephoto lenses. In particular, the 300mm lens, which is frequently used as a telephoto zoom lens, demonstrates high resolution performance from the center to the corners of the image. The number of lens elements used in the lens contributes to its lightweight construction, and Tamron's renowned anti-reflective coating (BBAR, Broad-Band Anti-Reflection) delivers extremely clear and crisp images throughout the entire zoom range. In addition, the "Lens Compensation" function of Sony cameras can be used to achieve even higher image rendering performance.
This lens allows those who are trying a full-fledged telephoto lens for the first time or those who demand a compact and lightweight telephoto lens to enjoy the freedom of photography without worrying about size or weight.
Furthermore, it maintains a good balance even when used with APS-C size E-mount cameras, which are smaller than full-size cameras.

- Incorporates the RXD stepping motor unit
The RXD stepping motor unit, optimized for AF control and equipped with a sensor that detects the lens position with high precision, is used for AF drive. The RXD enables high-speed and precise AF operation, so that the camera can continue to accurately track the focus on subjects with intense motion that are expected to be shot with telephoto lenses. The camera is also extremely quiet, making it ideal for use in concert halls and other situations where quietness is required, as well as for video recording, where the sound of the lens being driven is easily recorded.
Furthermore, the lens is compatible with the Direct Manual Focus (DMF) feature of Sony cameras, which allows manual fine-tuning of focus without switching focus modes after focusing in AF mode.

- Filter diameter of ø67mm for ease of use as a series
The filter diameter is the same as that of our preceding series of lenses for full-size mirrorless cameras, such as the 17-28mm F/2.8 ultra-wide-angle zoom lens (Model A046) and the 28-75mm F/2.8 standard zoom lens (Model A036), with a unified filter diameter of ø67mm. By using this series as interchangeable lenses, various filters including PL filters and ND filters, as well as lens caps, can be shared for smoother shooting. This also minimizes the expense of purchasing an assortment of filters.

- Simple drip-proof construction with sealing at key parts of the lens barrel
The lens barrel has a simple drip-proof construction with sealing at key locations, including moving parts and joints, to prevent drips and splashes. Sony Telephoto
