The B070 is a large aperture zoom lens for APS-C cameras that's ideal for everyday shooting. It features a focal length range of 17 to 70mm and is designed with a 4.1x zoom ratio. It's the first F2.8 lens with a full-frame equivalent for APS-C cameras.

Focal Length Range of 17-70mm

Fast-aperture F2.8 Standard Zoom Lens

4.1x Zoom Ratio

Full-frame equivalent focal length of 25.5-105mm

• The Tamron 17-70mm F2.8 lens utilizes the company's renowned VC image stabilization technology to optimize its optical performance. It helps minimize the effects of camera shake, which can occur when shooting at low-light conditions.
• When shooting videos, the image stabilization capabilities of the lens are enhanced through the use of AI technology. The Tamron's new AF drive system features an RXD motor unit, which is designed to drive the lens.
• It can drive the lens without using a reduction gear. This feature allows you to maintain a sharp focus even while shooting videos and moving subjects.
• In addition to this, a sensor that is capable of detecting the position of the lens is also integrated to improve its precision. The quiet design of the Tamron 17-70mm F2.8 lens eliminates the concerns about the noises that might emanate from the drive motor when shooting videos.
• The new Tamron 17-70mm F2.8 lens is compatible with a wide range of features and functions for mirrorless cameras. Some of these include Eye AF, Direct Manual Focus, In-camera lens correction, and firmware updates.
• The Tamron VC image stabilization system was developed to help minimize the effects of camera shake. It can also help you get a sharper image by compensating for the movement of the camera.
• Aspherical lens are commonly used in zoom lenses to correct the effects of spherical aberrations. They can replace other optical components without compromising their quality.
• This lens features an internal focusing mechanism that prevents the barrel from rotating or extending while focusing. It is ideal for use with gradation or polarizing filters.
• The lens is protected from dirt and contamination thanks to a special coating that is designed to prevent water and oil droplets from adhering to the surface. The low dispersion index of light-dispersion elements (LD elements) helps reduce the appearance of chromatic aberrations and improve the overall quality of photos.
• The low color dispersion index of extra-low dispersion elements helps minimize the appearance of various chromatic aberrations, such as those that appear as fringes in the contrast edges. The Tamron 17-70mm f/2.8 lens is also splash-resistant.
• Its special seals ensure that it can be used in harsh weather conditions. The responsiveness of the RXD autofocus system makes it ideal for capturing motion images, such as those taken with subjects moving around.
• A constantly-detecting sensor ensures that AF-C can precisely target the appropriate rotation angle for shooting at lightning speed.
