Tamron SP 24-70mm f/2.8 Di VC USD G2 Lens for Canon

Sophisticated design delivers superb performance & ultra-high image quality

The use of specialised, high-quality glass materials assures accurate colour reproduction and superior sharpness, perfect for today’s high-pixelPIXELThe shortening of 'picture element', a basic unit of programmable colour forming the dots that make up an image. Pixel size depends on a camera’s resolution, which is measured in megapixels (MP), meaning millions of pixels. The more pixels on a sensor, the smaller they have to be to fit. An image's number (or density) of pixels correlate to the amount of information and image holds. Cameras with more pixels on the sensor have a higher pixel density and thus more resolving power, able to capture smaller details with much more clarity and accuracy. Higher resolution images can be cropped more agressively and also produce better quality large prints.-density cameras. Optical construction (17 elements in 12 groups) uses 2 XR (Extra Refractive Index) elements, 3 LD (Low Dispersion) elements, 3 GM (Glass-Molded aspherical) and one hybrid aspherical lens element. Together they minimise axial chromatic aberrations, transverse chromatic aberrations, spherical aberrations and distortion, and allow a compact design that achieves superior image quality.

Features

• EF-Mount Lens/Full-Frame Format
• ApertureAPERTUREAperture, shutter speed and ISO form what is known as the exposure triangle in photography. Aperture refers to an opening inside the lens, similar to the iris of your eye, that changes in diameter to control the amount of light that enters a camera. Aperture is expressed in f-stops: the lower the number, the larger the aperture, e.g. f/1.4 is larger than f/8. A larger (or wider) aperture allows more light to pass through the lens to the sensor (film) as a picture is taken, particularly useful in low-light conditions. A larger aperture also produces a shallower depth-of-field, and thus more background blur. Range: f/2.8 to f/22
• Two XR Elements, Three LD Elements
• Four Aspherical Elements
• eBAND, BBAR, and Fluorine Coatings
• Ultrasonic Silent Drive Autofocus Motor
• VC Image Stabilization
• Moisture-Resistant Construction
• Rounded 9-Blade Diaphragm
• Compatible with TAP-in Console

eBAND Coating provides superior anti-reflection properties & reduces ghosting & flareFLAREOccurs when a point light source such as the sun or an artificial light (that is brighter than the rest of the scene), hits the front element of a lens resulting in a lack of contrast, haze, or unwanted semi-transparent objects being present in the image. You can avoid lens flare with a lenshood or filters, however, the effect is also useful for bringing artistic elements into an image, such as sun rays peaking out from behind a rock formation.

The new A032 features Tamron’s original eBAND (Extended Bandwidth & Angular-Dependency) Coating, a technology combining a nano-structured layer that has an extremely low refractive index with conventional multiple-layer coatings to provide superior anti-reflection performance. The optimal application of this eBAND Coating in combination with Tamron’s BBAR (Broad-Band Anti-Reflection) Coating successfully and substantially curbs the ghosting and flare that can occur when photographing backlit subjects.

New Dual MPU (Micro-Processing Unit) control system*3 provides faster and more precise autofocus
and improved Vibration Compensation

The innovative control system uses a Dual MPU design with enhanced computing capacity. The MPUs have powerful, built-in DSP (Digital Signal Processor) blocks that achieve quicker and more precise AF performance, and more consistently powerful Vibration Compensation. The features combine to provide outstanding performance at night and in low light.

High performance MPU for AF dramatically improves autofocusing accuracy & speed

The A032 is equipped with its own MPU (micro-processor unit), with embedded DSP (Digital Signal Processor) blocks that enable high-speed digital signal processing, achieving both excellent responsiveness to signals from the camera and high-precision AF performance.

Dedicated MPU delivers the highest vibration compensation ability in class*2 (CIPA level of 5 stops*1).

The new A032 is equipped with Tamron’s proprietary VC (Vibration Compensation) system. Adding an MPU dedicated to VC processing unleashes a new-generation algorithm, ensuring the highest vibration compensation ability*2 in the class (CIPA level of 5 stops*1). Even in low light or with slow shutter speedSHUTTER SPEEDAperture, shutter speed and ISO form what is known as the exposure triangle in photography. Shutter speed is the length of time that a single frame is exposed for, more specifically how fast the shutter opens and closes to permit light entering the lens, to reach the sensor. A slow shutter speed means a longer exposure time useful for motion blur like the silky look of flowing water, whereas a fast shutter speed means a shorter exposure time useful for freezing the appearance of motion in images like a hummingbird in flight. It is measured in seconds starting at 1 second and halving our doubling in time. For example: 1/2s, 1/4s and 1/8s are all fractions of a second with 1/2s being the longest exposure time, 1/4s half of that and 1/8s another half etc.s, photographers can enjoy shake-free handheld shooting with ease and comfort.

Fluorine Coating & Moisture-Resistant Construction

The Fluorine Coating applied on the front element surface is water and oil-repellant and allows safe and easy removal of fingerprints, dirt and smudges. The coating also provides an enhanced level of durability, and will sustain its effectiveness for years. In addition, seals are located at the lens mount area and other critical locations to prevent infiltration of moisture and/or rain drops to provide Moisture-Resistant Construction. This feature provides an additional layer of protection when shooting outdoors under adverse weather conditions. 

Lens hood equipped with new, convenient locking mechanism

The lens hood is equipped with a locking mechanism, which prevents detachment due to unintentional contact during use.

Compatible with TAMRON TAP-in ConsoleTM, an optional accessory

The new A032 is compatible with the optional TAMRON TAP-in ConsoleTM, an optional accessory product that provides a USB connection to a personal computer, enabling users to easily update a lens’s firmware as well as customise features including fine adjustments to the AF and VC.

Manufacturing innovation with thorough attention to details based on the rigorous quality standards
worthy of the SP series

Tamron has enhanced the SP series lenses to fulfil high-level photographic requirements and provide the pleasure of ownership. While introducing a new exterior design, Tamron reviewed the SP series standards. The new SP series has been developed by setting rigorous standards for design, manufacturing and quality that apply to the optical design and mechanical design as well as such wide-ranging areas as the product’s robustness and improvements in a variety of individual functions. For this model, Tamron has introduced a unique MTF (Modulation Transfer Function) tester, which was developed exclusively for Model A032, and reviewed the management method. This has helped to achieve a more consistently superb optical performance, making it a lens that fulfils the demand for higher image quality that is compatible with the latest high-pixel cameras. To maximise the optical performance of the SP series, Tamron will continue to enhance the accuracy of the component parts of each lens element unit and improve the mechanical precision of the entire lens, thereby achieving a high overall performance.
