Tamron 17-70mm f/2.8 Di III-A VC RXD Aspherical Lens for Mirrorless Cameras (Nikon Z Mount)

Large Aperture Standard Zoom Lens

The 17-70mm F/2.8 Di III-A VC RXD (Model B070) is a large aperture everyday zoom lens for APS-C mirrorless cameras. This lens was created to achieve a broad zoom range and excellent image quality. With a focal length range of 17-70mm (a full-frame equivalent of 25.5-105mm), it's the world's first F2.8 standard zoom lens with a 4.1x zoom ratio for APS-C cameras.

Worry-free Still Photography and Video Capture

The 17-70mm F2.8 utilizes Tamron's highly regarded, proprietary VC image stabilization to maximize the inherent optical performance of the lens. It reduces the degradation of picture quality caused by minute camera shake that is likely to occur during handheld shooting at slow shutter speeds under low-light conditions indoors or at dusk. When shooting video, by leveraging AI technology, image stabilization performance improves compared to conventional models.

Superb AF Keeps it Sharp and Quiet

The AF drive incorporates an RXD (Rapid eXtra-silent stepping Drive) stepping motor unit. RXD uses an actuator that is able to precisely control the rotational angle of the motor, allowing it to drive the focusing lens without passing through a reduction gear. The addition of a sensor that detects the position of the lens to a high degree of accuracy enables high-speed and precise AF, which allows you to maintain razor-sharp focus when shooting continually moving subjects or filming video. The lens is also remarkably quiet, eliminating concerns of drive sounds being picked up while shooting video

Built with Mirrorless in Mind

Tamron's new 17-70mm F2.8 zoom is compatible with many of the advanced features that are specific to mirrorless cameras. This includes: Fast Hybrid AF, Eye AF, Direct Manual Focus (DMF), In-camera lens correction (shading, chromatic aberration, distortion), and Camera-based lens unit firmware updates.

VC (Vibration Compensation)

Vibration Compensation, Tamron-developed image stabilization technology, that compensates for unwanted camera movement for sharper images. Shutter speeds of up to 5 EV stops slower are possible with the VC image stabilizer.

Aspherical Lens

Aspherical lenses correct spherical aberrations (focus errors) in zoom lenses. They can replace several other optical elements without loss of quality, contributing to a more compact lens design.

Internal Focusing (IF) System

Internal focusing prevents the barrel from extending and rotating during focusing. The lens is easier to handle and is suitable for use with polarizing or gradation filters.

Fluorine Coating

Fluorine Coating protects the front lens from contamination. It prevents oil and water droplets from sticking to the surface. Fingerprints and dirt are easier to remove.

Low Dispersion

LD elements have particularly low color dispersion index. They reduce chromatic aberrations that appear as color fringes on the contrast edges and reduce image sharpness.

XLD (Extra Low Dispersion) Glass

Extra-Low Dispersion elements have particularly low color dispersion index. They reduce chromatic aberrations that appear as color fringes on the contrast edges and reduce image sharpness.

Moisture Resistant Construction

The lens is splash-resistant. All critical areas have special seals. Lenses with this feature are ideal for outdoor use in bad weather.

RXD (Rapid eXtra silent Drive)

RXD autofocus is highly responsive, making it ideal for shooting stills and video of subjects in motion. A sensor constantly detects the current focus setting, allowing the continuous autofocus (AF-C) to precisely target the rotation angle required for focus at lightning speed.
