Tamron 28-300MM F/3.5-6.3 DI VC PZD

After the 18-200mm f/3.5-6.3 Di III VC for Canon EOS M (price & specs), Tamron today announced also the 28-300mm F/3.5-6.3 DI VC PZD for Canon EF mount.

The Tamron 28-300mm F/3.5-6.3 DI VC PZD will start ship June 26 and sells for $849, pre-order options: Adorama | B&H Photo

Tamron press release:

TAMRON ANNOUNCES DEVELOPMENT OF AN ADVANCED NEW ALL-IN-ONE™ WIDE-ANGLE TO TELEPHOTO ZOOM LENS FOR FULL-FRAME DSLR CAMERAS

28-300MM F/3.5-6.3 DI VC PZD (MODEL A010)

Innovative All-In-One™ zoom integrates state-of-the-art optical design, PZD (Piezo Drive)(1) and Tamron’s exclusive VC (Vibration Compensation)(2) system to achieve superb image quality in a remarkably compact, lightweight package.

February 6, 2014, Saitama, Japan. -February 6, 2014, Saitama, Japan – Tamron Co., Ltd. (President & CEO: Morio Ono), a leading manufacturer of precision optics, has announced the development of 28-300mm F/3.5-6.3 Di VC PZD (Model A010), an advanced new All-In-One™ zoom lens for full-frame DSLR cameras. 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.

Since the launch in 1992 of the 28-200mm (Model 71D) high-power zoom lens – which featured a revolutionary compact, lightweight design – Tamron has been continually expanding its portfolio of world class optics to benefit consumers. Having revolutionized the optical design of the previous 28-300mm (Model A20), Tamron is developing a powerful new, high-power zoom lens for full-frame DSLR cameras that enhances image quality and incorporates the PZD (Piezo Drive)—a standing-wave ultrasonic motor system optimized for swift, quiet AF—and the acclaimed VC (Vibration Compensation) mechanism in an amazingly compact configuration.

Featuring a new, sophisticated external finish, this lens complements the performance and style of full-frame DSLRs, while delivering the practical advantages of an All-In-One™ zoom lens.

Product Highlights

  • State-of-the-art optical design technology delivers superior image quality.
    The advanced optical construction of this lens includes four elements of LD (Low Dispersion) glass, three Molded-Glass Aspherical elements, one Hybrid Aspherical element, 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 its design contributes to making this outstanding lens as compact and lightweight as possible, while minimizing aberrations, resulting in superior image quality. Particularly impressive is the thorough compensation of chromatic aberrations at the telephoto end, yielding images of enhanced clarity and crispness.
  • Focus on portability – The lens is now even smaller and lighter.
    In addition to state-of-the-art optical design that facilitates downsizing of the lens body, the mechanical design, which incorporates a highly sophisticated multi-stack-cam layout that takes up far less space, and PZD (Piezo Drive), an autofocus drive system with a simpler, more compact structure, has made it possible to reduce the overall dimensions of this lens compared to the existing Tamron 28-300mm (Model A20). These technologies are the fruit of Tamron’s more than 20 years of research and development in the high-power zoom lens field.
  • Advanced anti-reflection coating.
    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.
  • Upgraded cosmetic design – Elegant tungsten silver brand ring.
    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 full-frame DSLR users. Employing a sophisticated linear pattern rubber grip on the zoom and focus rings and an elegant tungsten silver name-brand ring, this newly designed model accentuates its visceral presence with understated elegance and class.
  • PZD (Piezo Drive) delivers faster, quieter autofocus action.
    The PZD (Piezo Drive), a standing-wave ultrasonic motor system, delivers faster, quieter, more precise action when the autofocus is engaged. The full-time manual focus system is easy and intuitive, enabling quick and convenient manual focus at any time.
  • Sharper images with VC (Vibration Compensation)
    Tamron’s acclaimed VC (Vibration Compensation) mechanism reduces image blur caused by camera shake to deliver significantly sharper images even when shooting handheld.
  • Circular diaphragm facilitates achieving spectacular blur effects
    Using a circular diaphragm(3), this lens achieves spectacular background blur effects that enable creative use of depth of field.
  • Moisture-resistant construction for worry-free outdoor shooting.
    Moisture-resistant construction helps prevent moisture from penetrating the lens.

(3) This circular diaphragm retains a nearly circular shape even at two stops down from its maximum aperture.
