The Tamron 17-70mm f/2.8 Di III-A VC RXD lens, with its adaptable zoom range and striking design, offers a focal length equivalent to 25.5-105mm. This wide to short-telephoto range is particularly well-suited for everyday photography, while the constant maximum aperture of f/2.8 facilitates shooting in challenging lighting environments and enhances depth of field control. The lens is further enhanced by a collection of specialized optical elements, including aspherical and low dispersion components, which ensure well-corrected images characterized by exceptional sharpness, clarity, and color fidelity. Additionally, the individual elements are treated with Tamron's BBAR coating, effectively minimizing flare and ghosting, thus providing improved contrast in backlit and harsh lighting situations.
Perfect For A Broad Range Of Situation
This adaptable zoom lens allows for photography across various genres, encompassing wide-angle vistas to telephoto captures. Featuring a focal length range of 17mm to 70mm (equivalent to 25.5-105mm in full-frame terms), it stands as the world's inaugural fast-aperture f/2.8 standard zoom lens designed for APS-C mirrorless cameras, achieving an impressive 4.1x zoom ratio. It is perfectly suited for numerous situations, including portraits, street photography, landscapes, and close-up shots.
The 17-70mm f/2.8 lens features a consistent maximum aperture of f/2.8 across its entire zoom range, distinguishing it from variable aperture lenses, which experience changes in maximum aperture as zoom adjustments are made. This constant f/2.8 aperture, combined with exceptional optical performance, enables the 17-70mm f/2.8 to capture subjects with remarkable clarity, whether in wide-angle or telephoto settings. The primary benefits of a fast f/2.8 aperture include: A) enhanced capability for shooting in low-light conditions, B) the creation of aesthetically pleasing and soft bokeh, and C) improved depth-of-field control, which is particularly advantageous for portrait photography by allowing the background to be blurred, thereby emphasizing the main subject. The lens's optical construction comprises 16 elements arranged in 12 groups, designed to achieve outstanding optical performance through the strategic use of two GM (Glass Molded Aspherical) elements and one aspherical hybrid element. This optical configuration guarantees high resolution and contrast not only in the center of the image but also throughout the corners and edges.
VC Image stabilization
The 17-70mm f/2.8 is a versatile standard zoom lens that excels in both still photography and video production. This lens features minimal focus breathing, a phenomenon that can alter the angle of view based on the focusing distance during video recording. By minimizing focus breathing, the 17-70mm f/2.8 allows users to fully express their creative vision. Furthermore, the lens is equipped with a silent RXD AF drive motor and a VC image stabilization system, making it suitable for handheld video shooting.
The 17-70mm f/2.8 incorporates TAMRON's esteemed VC image stabilization system, which enhances the lens's natural optical capabilities. This system effectively minimizes the deterioration of image quality that can result from subtle camera movements, particularly during handheld photography at slower shutter speeds in low-light environments, such as indoors or during twilight. Additionally, when capturing video, the image stabilization, powered by AI technology, will automatically adjust to provide optimal compensation for various shooting scenarios.
High Performance Autofocus
The autofocus mechanism of the 17-70mm f/2.8 features an RXD motor unit designed to maintain focus on dynamic subjects. The RXD system employs an actuator that meticulously regulates 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. Additionally, the focusing system operates smoothly and quietly, allowing photographers to work in serene settings without concern for distracting drive sounds.
Minimum Object Distance
This sophisticated lens is capable of achieving remarkable close focus, distinguishing itself as a standard zoom lens designed for APS-C mirrorless cameras. The minimum object distance (MOD) measures a mere 0.19m (7.5 in) at the wide-angle setting and extends to 0.39m (15.4 in) at the telephoto setting. When capturing images in close proximity to the subject, this lens facilitates the creation of striking visuals with beautifully blurred backgrounds, a characteristic typically associated with fast-aperture lenses. This versatility enables the production of distinctive photographs across a range of subjects, including snapshots, portraits, landscapes, and architectural scenes. Close-up images taken at the 17mm focal length fully exploit the unique perspective that only genuine wide-angle lenses can provide.
Compact and Lightweight Design
This lens has been developed with a steadfast commitment to portability, specifically designed for APS-C cameras. Despite featuring high-performance Vibration Compensation (VC), the 17-70mm f/2.8 remains remarkably lightweight and compact, measuring only 119.3mm (4.7 in) in length, with a maximum diameter of 74.6mm and a weight of 525g (18.5 oz). It serves as an exceptionally versatile option for travel, catering to those who favor smaller bags, and is an excellent choice for everyday use.
