Tamron 28-300mm f/3.5-6.3 Di VC PZD
(From Tamron lens literature) Tamron Co., Ltd., 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.
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.
- 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 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.
- 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)*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.
- 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.
- 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.
- 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.

9 out of 10 points and recommended by Kranang (1 reviews)Fantastic range. Light and small. Sharp enough.Some vignetting. Corner sharpness wide open.
My most handy walk-around lens for my A99. Å day-light lens. Fast enough.reviewed July 26th, 2015
7 out of 10 points and recommended by mu55ster (10 reviews)Small, Light, Better than expectedwould it have been better if it was just alittle bigger?
After realizing that i was constantly shooting my 24-105L at f8 or f11, and at the same time leaving my 100-300 f5.6L in the car rather than taking it up to the 24th floor apartment where it would have been good to have for some quick snaps I decided to look into the dreaded field of superzooms.reviewed April 20th, 2015 (purchased for $879)
I wasn't expecting the best image quality but i'm pretty demanding of all my other gear - so i was willing to accept soft corners and pretty ordinary quality at 300mm - this lens surprised me.
At 300mm, yes, the quality doesn't blow you away, but it's about the same as my old 100-300L was at f5.6, plus it has a lightroom profile and stabilization. Between 28 and 200mm on my canon 6D i get sharpness into the corners at f8 and f11 - i'm yet to test it properly wide open, but thats not why i bought it anyway. There is a good amount of CA/fringing but lightroom cleans that up and i have noticed that flare of bright objects isn't as nice as from my other lenses. i have a feeling it's backfocusing at 300mm but is spot on at wider lengths.
Build quality is great, although for the price i was kid of expecting it to be this good. I would have been happier if the lens was just alittle larger (taking 72 or even 77mm filters, it takes 67mm) if it meant that the quality at 300mm could have been just slightly better or the aperture f5.6 instead of 6.3. It would also have been nice if the zoom ring turned the same way as canon lenses for the canon version - it's going to take some getting used to, but i'm never going to be using this lens in a high pressure shoot where that's going to become close to an issue.
There aren't many reviews out there, this is a good lens, possibly the best in it's class from what i can figure, and miles ahead of Tamrons older offerings in this segment - i'm quite happy and still alittle astonished by this lens - it actually comes close enough that it may replace the 24-105L and 100-300L in my kit
