Tamron is developing a cutting-edge high-power zoom lens, with expanded focal lengths at both wide-angle and telephoto ends of the zoom range, providing a zoom ratio of approximately 18.8X.
A high-performance, high-power zoom lens that delivers focal lengths extending from an unprecedented 16mm at the wide-angle end up to a long-range telephoto 300mm!
Incorporates PZD (Piezo Drive)*1 and Tamron’s exclusive VC (Vibration Compensation)*2 system to further enhance the real-world performance of this next-generation “all-round lens”.
February 6, 2014, Saitama, Japan – Tamron Co., Ltd. has announced the development of an advanced new all-in-oneTM zoom lens exclusively for digital SLR cameras with APS-C size image sensors that provides an amazing 18.8X zoom ratio. The lens sample will be on display at the Tamron booth at the CP+ 2014, which will be held from February 13 to 16 in Yokohama, Japan.
Responding to consumers’ demand for expanded focal lengths both at the wide-angle end of the zoom range and the telephoto end, Tamron has begun developing a completely new all-in-oneTM zoom lens design that provides an impressive focal length range extending from 16mm true wide-angle to 300mm super-telephoto.

Product Highlights

1.  A further expansion of the imaging range. With a minimum focal length of 16mm (35mm film equivalent: 24.8mm) at the wide-angle end of the zoom range, and a maximum focal length of 300mm (35mm film equivalent: 465mm), this remarkable new lens provides a zoom ratio of approximately 18.8X.
Responding to requests from consumers who wanted to be able to photograph subjects with a wider viewing angle than is possible with conventional high-power zoom lenses, Tamron has begun developing a unique lens with a minimum focal length of 16mm. At the telephoto end, the maximum focal length has been increased to an impressive 300mm. Users of this new lens can enjoy unprecedented framing flexibility by easily adjusting the angle of view using the convenient zoom ring.
2.  Superior, reliable image quality with a universal lens.
The lens construction features 16 elements in 12 groups. This includes three Molded-Glass Aspherical elements, one Hybrid Aspherical element, two LD (Low Dispersion) elements, one XR (Extra Refractive index) glass element, and one element of UXR (Ultra-Extra Refractive Index) glass, which has greater refractive index than XR.  The full use of specialized glass elements in the design contributes to thorough compensation of optical aberrations. In addition, the use of the latest coating technology for suppressing reflections on lens element surfaces minimizes unwanted flare and ghosting and assures sharp, crisp, high-contrast images.
3.  Using a new design approach to create an ultra-compact lens.
The latest optical technology has been used to provide an expanded zoom range (compared to the B008) at both the wide-angle and telephoto ends, without necessitating the use of an oversized lens body. By employing UXR glass (which helps to reduce the size of the front lens diameter), an optimized layout of the Molded-Glass Aspherical elements, and adopting a 5-lens-group zoom system approach to provide enhanced design flexibility, the new lens embodies the fusion of state-of-the-art optical design, sophisticated mechanical design, and high-precision lens manufacturing technology, thereby attaining a compact size, an unprecedented zoom range, and superior image quality.
4.  A minimum focusing distance of just 0.39 meters supports an extensive range of macro photography capabilities.
The new lens provides a minimum focus distance of 0.39 m over the entire zoom range, with a maximum magnification ratio of 1:2.9. This makes it possible to get right up close to the subject of the photo to enjoy easy, stress-free macro photography.
5.  PZD (Piezo Drive) delivers faster, quieter autofocus action.
The PZD (Piezo Drive)*1, an advanced standing-wave ultrasonic motor system, delivers faster, quieter, more precise AF action when the autofocus is engaged. There is enhanced support for contrast-detection AF capabilities, and focusing when in live-view mode has been made smoother. The new lens also features full-time manual focus, a function that was not provided by B008, making manual focusing more convenient.
6.  Sharper images with VC (Vibration Compensation)
Tamron’s acclaimed VC (Vibration Compensation)*2 mechanism is incorporated into the new lens.*3 VC reduces image blur caused by camera shake to deliver significantly sharper images even when shooting handheld at long telephoto settings
7.  Moisture-resistant construction for worry-free outdoor shooting.
Moisture-resistant construction helps prevent moisture from penetrating the lens.
8.  Upgraded cosmetic design.
Tamron has upgraded the cosmetic design and finish of this lens to create a more sophisticated, high-end look in keeping with the demands of discerning DSLR users. Employing a sophisticated linear pattern rubber grip on the zoom and focus rings, and an elegant tungsten-silver name-brand ring, etc., this newly designed model accentuates its visceral presence with understated elegance and class.
*1 PZD (Piezo Drive) is a standing-wave type ultrasonic motor system developed by Tamron. It delivers outstanding speed and quiet operation in the AF mode. It also provides greater flexibility in design compared with ring-type ultrasonic motors, thus contributing to reduced lens size.
*2 VC (Vibration Compensation) is Tamron’s proprietary tri-axial image stabilization mechanism.
*3 The Sony mount model does not include VC, since the bodies of Sony DSLR cameras include built-in image stabilization functionality. The name of the Sony mount model is “16-300mm F/3.5-6.3 Di II PZD MACRO” without the VC designation.
