目前看起來Canon會不會爆發還不知道
但是繼2013 Sigma連發多款口碑極佳的新款鏡之後
2014的騰龍也接著爆發啦
之前才剛發表150-600超望遠變焦
現在又推出all-in one的全功能旅遊鏡28-300mm F/3.5-6.3 Di VC PZD
這是一款成像圈足以給FF機使用的鏡頭
預計在2014年二月13-16的橫濱CP+正式發佈
這隻新鏡是繼任自1992年就發表的28-200mm之後的再一次大改推出
適合以一機一鏡走天下的使用目標為主的全功能旅遊鏡
預計發表Canon/ Nikon/ Sony 三種版本
鏡頭規格最後的PZD是代表這支鏡頭安裝了新開發的強力電壓驅動器
用來更快速更有效率的推動騰龍安裝在這支鏡頭內的USD超音波對焦馬達
預計可以大幅強化騰龍過去對焦速度較慢的弱項
私心希望這個PZD從近距離突然對焦到無限遠易拉風箱的老症頭也能一併改善阿~
這是我每次想要下手買騰龍時心裡的最大障礙
此鏡的八大特點(根據下面原文的說法)
一. 超高畫質
二. 攜帶性提高, 大幅減輕體積重量.
三. 使用了先進的抗耀光鍍膜
四. 鏡身質感將大幅升級,具有優雅的銀環裝飾與高階鏡頭等級的外觀.
五. 使用PZD增快對焦效率並且支援全時手動.
六. 內建防手震(Sony版的除外)
七. 使用圓形光圈葉片, 創造漂亮的散景.
八. 鏡身具有防潮設計適合戶外使用.
(看規格表所示,口徑只有67mm 重量只有540克 真是變得頗小頗輕.)

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)*1—a standing-wave ultrasonic motor system optimized for swift, quiet AF—and the acclaimed VC (Vibration Compensation)*2 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.
Highlights and specifications after the break
Product Highlights
1.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.
2.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.
3.Advanced anti-reflection coating
The application of BBAR (Broad-Band Anti-Reflection) coatings for suppressing reflections on lens element surfaces minimizes unwanted flare and ghosting to deliver sharp, crisp, high-contrast images.
4.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.
5.PZD (Piezo Drive) delivers faster, quieter autofocus action
The PZD (Piezo Drive)*1, 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.
6.VC (Vibration Compensation)
Tamron’s acclaimed VC (Vibration Compensation)*2mechanism reduces image blur caused by camera shake to deliver significantly sharper images even when shooting handheld.
7.Circular diaphragm facilitates achieving spectacular blur effects
Using a circular diaphragm*4, this lens achieves spectacular background blur effects that enable creative use of depth of field.
8.Moisture-resistant construction for outdoor shooting
Moisture-resistant construction helps prevent moisture from penetrating the lens.
*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 “28-300mm F/3.5-6.3 Di PZD” without the VC designation.
*4 This circular diaphragm retains a nearly circular shape even at two stops down from its maximum aperture.
