Tamron 17-28mm f/2.8 Di III RXD Lens for Sony E **OPEN BOX**

The Tamron 17-28mm f/2.8 Di III RXD is a highly adaptable zoom lens designed for full-frame Sony E-mount mirrorless cameras, offering a flexible wide-angle range. This lens spans ultra-wide to wide focal lengths, making it ideal for capturing landscapes, astrophotography, and architectural subjects. Its constant maximum aperture of f/2.8 enhances low-light performance and provides greater control over depth of field. The optical design includes both XLD and LD elements, which effectively minimize chromatic aberrations and color fringing, resulting in superior image clarity and color fidelity. Additionally, the lens is equipped with Tamron's BBAR coating, which reduces flare and ghosting, thereby improving contrast in challenging lighting situations. The RXD stepping motor contributes to its versatility by delivering fast and nearly silent autofocus, suitable for both still photography and video, while also allowing for full-time manual focus override and a minimum focusing distance of 7.5 inches. Furthermore, the lens is constructed to withstand adverse weather conditions, featuring a moisture-resistant design and a fluorine-coated front element that helps prevent fingerprints and smudges.

Compact and Easy To Take Everywhere

Tamron enhances the excitement of large aperture ultra wide-angle photography by prioritizing usability in this lens design. The carefully chosen 17-28mm zoom range contributes to its remarkably compact dimensions, measuring only 99mm (3.9 in) in length and weighing a mere 420g (14.8 oz). Notably, the lens maintains a consistent length during zooming, which facilitates stable handling and shooting operations. Furthermore, the lens features a 67mm filter size, which is relatively small for a large aperture ultra wide-angle zoom lens. It also shares the same filter diameter as the high-speed standard zoom lens in the series, the 28-75mm f/2.8 Di III RXD (Model A036), allowing for the use of identical filters, lens caps, and other accessories across both models.

Beautifully Capture Every Scene 

The 17-28mm zoom lens delivers exceptional image quality without compromise, all while maintaining a compact design. It features two LD lens elements and one XLD element, which closely resembles fluorite, strategically positioned to eliminate chromatic and other types of aberrations. Furthermore, the BBAR (Broad-Band Anti-Reflection) Coating applied to the lens surfaces minimizes ghosting and flare, which are common challenges when photographing against bright backlighting, such as during sunset. By utilizing advanced camera functions, this lens ensures outstanding optical performance that aligns with the latest high-resolution image sensors, providing sharpness from edge to edge across the entire zoom range. The 17-28mm zoom lens opens the door to the stunning realm of ultra wide-angle photography.

Superior Close-up Shooting

The 17-28mm zoom lens offers a minimum object distance (MOD) of 0.19m (7.5 inches) at the 17mm wide-angle setting, achieving a maximum magnification ratio of 1:5.2. Conversely, at the telephoto end, the MOD increases to 0.26m (10.2 inches), with a maximum magnification ratio of 1:6. This allows for close proximity to subjects, enabling impactful photography. The lens captures the distinctive perspective characteristic of ultra wide-angle lenses, while also allowing for soft focus effects through a shallow depth of field when the aperture is opened and the subject is approached. It is versatile, functional, and remarkably impressive all at once.

High Performance Autofocus

The autofocus mechanism in the 17-28mm zoom 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 sensor that accurately monitors the lens position facilitates rapid and precise autofocus, making it particularly suitable for capturing continuously moving subjects or for video recording. This lens is ideal for street photography and spontaneous group shots. Additionally, the focusing system operates smoothly and quietly, allowing for video recording without the concern of capturing unwanted ambient sounds.

Durable Design

The design of the 17-28mm zoom lens is not only aesthetically pleasing but also highly functional. It boasts an outer casing that closely conforms to the sleek shape of the lens body, complemented by a meticulously crafted Luminous Gold brand ring and a sturdy, precise metal lens mount. The Luminous Gold brand ring enhances the distinctive appearance of a Tamron lens, whether it is used independently or mounted on a camera body.
