* Among ultra-wide-angle zoom lenses for APS-C DSLR cameras (As of January, 2017. Source: Tamron)
The optical design includes 16 elements in 11 groups. A new large aperture aspherical lens and LD (Low Dispersion) lens elements deliver exceptional resolution across the complete zoom range— combined with stable imaging across the entire frame. The lens also corrects comatic and transverse chromatic aberration, as well as distortion that often crops up on other wide-angle lenses. Together with Tamron’s unique BBAR (Broad-Band Anti-Reflection) Coating, which improves light transmission and suppresses reflection and dispersion on the lens surface, this new ultra-wide-angle zoom has been entirely reimagined to control flare and ghosting. The result: clear, crisp images, every time.
Tamron’s unique VC (Vibration Compensation) technology makes it easy to enjoy handheld, wide-angle shooting, even in low-light environments such as evening and indoors. While maintaining the compact design of our previous Model B001, Tamron has optimized the actuator and control algorithm in order to incorporate VC into our new Model B023. Now you can unleash the power of high quality imaging, without worrying about your images being spoiled by the jittery effects of handheld shooting.
With this lens, Tamron introduces the HLD (High/Low torque-modulated Drive) AF drive system. The excellent driving power of the all-new HLD enables stable and precise focusing, even with the large focusing lens elements used on Model B023. What’s more, the Full-time Manual Focus override allows you to make fine adjustments—without having to switch from AF to MF mode.
High performance packed into a compact body
A shortened overall length vastly improves optical performance while maintaining a compact size—even with advancements such as VC and the newly developed HLD. When combined with an APS-C DSLR camera, this lens packs a world of performance into a lightweight, portable body.
Model B023 is equipped with a Full-time Manual Focus override mechanism that enables the user to freely select the focus point. A photographer shooting with AF can instantaneously make fine focusing adjustments using MF, without having to switch the AF-MF mode back and forth. This makes it possible to enjoy creating photographic works with a more refined style exactly according to the users' intent, in wide-angle photography as well.
The front surface of the lens element is coated with a protective fluorine compound that is water- and oil-repellant. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture and fingerprints.
An electromagnetic diaphragm system, which has been a standard feature for Canon-mount lenses, is employed in Nikon-mount lenses*. More precise diaphragm and aperture control is possible because the diaphragm blades are driven and controlled by a motor through electronic pulse signals.
* Available only with cameras compatible with the electromagnetic diaphragm: D3100, D3200, D3300, D3400, D5000, D5100, D5200, D5300, D5500, D5600, D7000, D7100, D7200, D300, D300s (As of 01/2017)
For greater protection when shooting outdoors, leak-proof seals throughout the lens barrel help protect your equipment.
The optional TAP-in Console™ provides a USB connection to your personal computer, enabling you to easily update your lens’s firmware as well as customize features including fine adjustments to the AF and VC.
With this new ultra-wide-angle zoom lens, Tamron has merged beautiful craftsmanship with intuitive design. From the outer casing hugging the contours of the lens, to the deftly worked Luminous Gold brand ring and meticulous construction, the quality of this lens is second to none. Even details like the shape of the switch box, distant-scale window, and the precision and stability of the metallic mount reveal a commitment to functionality, as well as design.
The result is a next-generation lens that’s easy to use, yet loaded with cutting-edge technology.
