  • Moisture-Resistant Construction for added protection

Introducing a new a standard zoom lens for Sony E-mount APS-C mirrorless cameras: Tamron 17-70mm F/2.8 Di III-A VC RXD (Model B070). It features a maximum aperture of F/2.8 across the entire 4.1x zoom ratio that covers a focal length of 17-70mm that is ideal for regular use (a full-frame equivalent of 25.5-105mm) and superb optical performance. It is a small, lightweight lens that is also equipped with Tamron's VC, Vibration Compensation, mechanism to minimize camera shake. This VC mechanism also leverages AI technology when shooting video.

Expand your photo experiences with an advanced standard zoom lens
The world's first1 17-70mm F/2.8, large aperture standard zoom lens for APS-C mirrorless cameras. Even with VC and a focal length expanding to 70mm, this lens has outstanding optical performance compared to its competitors. The optical construction of the new 17-70mm F/2.8 Di III-A VC RXD features 16 elements in 12 groups. Two GM (Glass Moulded Aspherical) lens elements and one hybrid aspherical lens element are precisely arranged to maintain high-resolution performance from edge to edge. In-camera lens correction (shading, chromatic aberration, distortion) are available too.

Upgraded VC with a dual MPU
The new 17-70mm F/2.8 Di III-A VC RXD features a control system that uses a Dual MPU (Micro-Processing Unit) process. In addition to an MPU with built-in DSP (Digital Signal Processor) blocks for superior signal processing, Tamron has added an MPU dedicated solely to vibration compensation. The result is quicker, more precise AF performance and more consistently powerful VC (Vibration Compensation). The VC is also especially optimized for video shooting.

High quality images and perfect handling
The 17-70mm F/2.8 Di III-A RXD 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. The 17-70mm F/2.8 has a focal length range of 17-70mm, equivalent to 25.5-105mm on full-frame cameras (4.1x zoom ratio).

Superior AF keeps it sharp and still
The AF drive incorporates a sensor that accurately detects the position of the lens while the RXD motor unit delivers optimized AF control. This achieves very fast and accurate autofocus operation and allows users to maintain tack-sharp focus on continuously moving subjects shot at the standard zoom position. Thanks to the exceedingly quiet AF, the lens can be used discreetly in concert halls and other situations that require low noise levels, and obviously for video recording.

VC for video shooting
By leveraging AI technology, image stabilization performance improves compared to conventional models when shooting video. The lens automatically switches to a video-tailored VC mode only when shooting video. This VC mode compensates for vibration that occurs during handheld still shooting, and that is caused by motion such as panning and tilting, without the unnatural behaviour seen with previous VC technology. It does not, however, completely eliminate shaking when shooting while running, walking or going up or downstairs, as is possible with a gimbal.

Seals are located at the lens mount area and other critical locations to deter infiltration of moisture and/or rain drops and afford Moisture-Resistant Construction. This feature provides an additional layer of protection when shooting outdoors under adverse weather conditions.

Understanding: Aperture

Aperture is the opening in a camera lens that controls how much light enters the camera. It's measured in f-stops like f/2.8 or f/8. Lower f-stop numbers mean wider openings, letting in more light and creating a shallow depth of field (blurry background). Higher f-stop numbers mean smaller openings, letting in less light and creating a larger depth of field (more of the scene in focus). Aperture also affects the quality of out-of-focus areas in the image (bokeh).

Understanding: Lens Types

Different lenses have different purposes to achieve different styles of images, some popular ones include:
Prime Lens: Fixed focal length, sharp images, great for portraits and dark settings.
Zoom Lens: Variable focal length, versatile for different shots and everyday use..
Wide-Angle Lens: Captures wide scenes like landscapes.
Telephoto Lens: Magnifies distant subjects, ideal for sports & wildlife.
Macro Lens: Perfect for close-up photography of small subjects.
Fisheye Lens: Ultra-wide perspective, creates unique images.

Understanding: Lens Mounts

Different camera brands use different lens mounts, which are like connectors that attach lenses to camera bodies. Each mount is specific to a particular brand and camera series. For example, Canon uses the EF and RF mounts, Nikon uses the F mount, Sony uses the E mount for its mirrorless cameras. These mounts dictate which lenses are compatible with which cameras. Some brands offer adapters to use lenses from other systems, but it's essential to ensure compatibility for proper functionality and autofocus performance.

Understanding: Manual and Autofocus

Manual focus and autofocus are two ways to adjust the sharpness of a camera lens. With manual focus, you turn a ring on the lens to bring the subject into focus yourself, giving you full control over what appears sharp in the image. Autofocus, on the other hand, relies on the camera's built-in technology to automatically adjust the focus for you, usually by detecting contrast or phase differences in the scene. Autofocus can be convenient, especially for fast-moving subjects or when you need to capture a quick shot, whereas manual focus allows for precise adjustments and creative control over the final image.
