The Tamron 17-70mm F2.8 Di III-A RXD Sony E (APS-C) is a large aperture everyday zoom lens for Sony E-mount APS-C cameras offering a broad zoom range, excellent image quality and versatile F2.8 maximum aperture across the whole zoom range. This lens focuses very close, featuring a minimum object distance of 0.19m at the wide-angle and 0.39m at the telephoto end for expressive images with highly blurred backgrounds. The small and lightweight design also includes Tamron's proprietary VC (Vibration Compensation) which utilises AI technology when shooting video for stable footage.
Tamron 17-70mm F2.8 Di III-A RXD Sony E (APS-C) features Moisture-Resistant Construction, Fluorine Coating and a φ67mm filter size – the same as the Tamron series of lenses for full-frame mirrorless cameras. Compatible with many of the features that Sony builds into its cameras, including Fast Hybrid AF and Eye AF, the lens is the ideal everyday zoom lens for a multitude of situations. It is a highly practical lens that enables photographers to attain high image quality while enjoying the benefits of the large F2.8 aperture.
With a focal length range of 17-70mm, equivalent to 25.5-105mm on full-frame cameras. The Tamron 17-70mm F2.8 Di III-A RXD Sony E (APS-C) is the first F2.8 high-speed zoom lens in the world for APS-C mirrorless cameras to achieve a 4.1x zoom ratio.
The optical construction of the new 17-70mm F2.8 is equally impressive and features 16 elements in 12 groups. Two GM (Glass Molded Aspherical) lens elements and one hybrid aspherical lens element are precisely arranged to maintain high-resolution performance from edge to edge.
The Tamron 17-70mm F2.8 Di III-A RXD Sony E (APS-C) utilizes highly regarded VC image stabilisation to maximize the optical performance of the lens when shooting handheld by effectively compensating camera shake. When shooting video, image stabilisation is further improved by leveraging AI technology compared to more conventional modes of stabilisation.
The AF drive incorporates an RXD (Rapid eXtra-silent stepping Drive) stepping motor unit. The RXD actuator is able to precisely control the rotational angle of the motor, allowing it to drive the focusing lens directly without the use of a reduction gear. Additionally, a dedicated sensor senses the position of the lens to a high degree of accuracy - enabling both high-speed and precise AF which allows to maintain razor-sharp focus when shooting moving subjects or filming video.
The new Tamron 17-70mm F2.8 Di III-A RXD Sony E (APS-C) is compatible with many of the advanced features that are specific to Sony Mirrorless cameras. This includes:
The 17-70mm F2.8 zoom measures a scant 119.3mm (4.7 in) in length and 74.6mm in maximum diameter and weighs only 525g (18.5 oz). This is remarkable for a lens with built-in VC image stabilization. When used with Sony's APS-C mirrorless cameras, this zoom is nicely balanced and provides a comfortable user experience.
Developed under the concept of creating more user-friendly large aperture zoom lenses, the new Tamron 70-180mm F2.8 Di III VXD Lens for Sony FE offers just that. This lens features a compact and lightweight design while bringing the creative freedom of a large f/2.8 aperture to the discerning photographer. Its very short 0.85m (33.5 in) MOD (Minimum Object Distance) expands overall versatility. The 70-180MM F2.8 Di III VXD Sony FE sports the same 67mm filter threads as the rest of Tamron's "Dream Team" high-speed zoom lenses - a key advantage of this series is their portability and bright apertures. Currently, this series includes lenses such as the ultra-wide 17-28mm F/2.8 Di III VXD and the high-performance standard zoom 28-75mm F/2.8 Di III VXD.
Designed for full-frame Sony E-mount cameras, this lens provides users with complete portrait to telephoto lens range coverage, spaning a useful short-telephoto to mid-telephoto range. Its optical construction includes several special lens elements for overall superb imaging performance. Among them are, low dispersion and aspherical elements used to correct a variety of aberrations and a BBAR-G2 coating to reduce flare and ghosting for high contrast and colour accuracy expected of Tamron lenses.
The lens utilizes Tamron’s newly developed VXD (Voice coil eXtreme torque Drive) linear motor focus mechanism, which delivers notably fast, accurate, and quiet focusing performance. Not only is the autofocus drive quieter and quicker than ever before, but full-time manual focus control is also available. Additionally, a floating system is used to achieve excellent optical performance at all shooting distances. By simultaneously operating two VXD units via electronic control, the system produces clear and sharp images of all objects near and far.
Other features that support a great shooting experience include Moisture-Resistant Construction for added weather protection and Fluorine Coating for easy maintenance - enabling shooting in most conditions and protection against fingerprints and smudging. In addition, the 70-180mm F/2.8 is fully compatible with various mirrorless camera-specific features including Fast Hybrid AF and Eye AF.
Tamron’s first-ever linear motor AF drive focus mechanism called VXD (Voice-coil eXtreme-torque Drive) ensures stunningly fast and accurate auto-focusing. The floating system uses two high-speed, high-precision VXD units with advanced electronic control for fast and precise AF performance.
Optically, the lens features 19 lens elements 14 groups, including 1 extra-low dispersion (XLD) element, 5 low dispersion (LD) elements, 1 glass-moulded aspherical (GM) element, and 2 “hybrid” aspherical elements. All of these, paired with the second generation Broad-Band Anti-Reflection coating, promise exceptional image quality from edge-to-edge at every focal length, even wide open.
Tamron’s new 70-180mm F/2.8 Di III VXD is compatible with many of the advanced features that are specific to mirrorless cameras including:
*Features vary by camera. Please consult your camera’s instruction manual for details
Tamron is calling this “the lightest and most compact f/2.8 telephoto zoom in its class” - and with its 180mm maximum focal length and its extending zoom mechanism, it offers just that. It uses the same 67mm front filter thread as the 17-28 and the 28-75, weighs in at just 810g, and measures just 149mm in length at the 70mm setting.
Finally, as with the other lenses in the Di III lineup, the Tamron 70-180mm f/2.8 is moisture-resistant, features a fluorine coating on the front element to repel oil and water, and, since the lens does extend during operation, there’s also a zoom lock switch to keep it from expanding during transport.
