Brilliant Evolution

Superb image quality in a remarkably compact, lightweight package

As full-frame digital SLRs are more widely used by travellers and enthusiasts, their best partner is a a responsive, accurate high-power zoom lens. This All-In-One™ 28-300mm lens delivers superb image quality in a remarkably compact, lightweight package.

Tamron's acclaimed VC (Vibration Compensation) mechanism reduces image blur caused by camera shake to deliver sharp images even when shooting handheld in low light or at the telephoto end*. The PZD (Piezo Drive) provides noticeably faster, quieter autofocus action, allowing users to capture spontaneous moments in crisp images and to continue to shoot even when quiet operation is required.

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.

* The Sony mount does not include VC, as Sony digital SLR bodies include image stabilisation functionality. The Sony lens is designated as “28-300mm F/3.5–6.3 Di PZD”.

LD (Low Dispersion) element

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 specialised glass elements in its design contributes to making this outstanding lens as compact and lightweight as possible, while minimising aberrations, resulting in superior image quality.

XR
Extra Refractive Index

More compact lenses with superior image quality

XR (Extra Refractive Index) glass can bend light rays at steeper angles, thereby decreasing the physical length of the lens while enhancing imaging performance by minimising optical aberrations. With its superior light-bending power, XR glass makes it possible to design a short-barrel lens with the same light-gathering ability (aperture value) as a long-barrel lens – even with a smaller lens diameter. By using this principle Tamron has been able to shorten the length of the entire optical system and produce lighter, more compact lenses of the same speed, and also to provide greater zoom ranges in lenses that are much more convenient to carry and hand-hold.

XR glass is costlier than conventional glass but it yields enhanced optical power distribution, making the innovative XR lens designs possible.

UXR
Ultra Extra Refractive Index

XR glass enhanced

UXR glass is a development of XR glass, bending light even further. Like XR glass, UXR plays an important role in minimising the size and weight of the lens, optimising handling and dexterity.

ASL
Aspherical

Far superior image quality – while reducing lens size and weight

Tamron uses several hybrid aspherical lens elements in its lenses bearing the Aspherical designation. The benefits are two-fold: first, their non-spherical shapes virtually eliminate spherical aberration and image distortion. Second, as one hybrid aspherical lens element can take the place of multiple elements without compromising performance, they allow the lens to be much more compact.

As a result, these innovative optics have played a crucial role in delivering uniformly high image quality across all apertures and focal lengths of extraordinarily compact ultra-zoom lenses.

Hybrid aspherical construction

LD
Low Dispersion

Sharpens edges by reducing 'colour fringing'

Chromatic aberration occurs when a lens element refracts different wavelengths of a ray of light – its rainbow colours – at very slightly different angles. This results in the 'colour fringing' that reduces the sharpness of an image. LD elements are made from special glass materials with extremely low dispersion indices (i.e. the refraction of a ray of light into rainbow colours is extremely narrow). Thus they effectively compensate for chromatic aberration at the centre of the field (on axis), a particular problem at long focal lengths (the telephoto end of the zoom range), and for lateral chromatic aberration (toward the edges of the field) that often occurs at short (wideangle) focal lengths.

Although costly, LD glass materials result in clear, vivid image quality.

Low Disperison glass

BBAR
Broad-Band Anti-Reflective coating

Cleaner, crisper images without flare or ghosting

The application of BBAR (Broad-Band Anti-Reflection) coatings for suppressing reflections on lens element surfaces minimises unwanted flare and ghosting to deliver sharp, crisp, high-contrast images.

Rounded diaphragm blades give natural-looking circular blur highlightsRounded diaphragm

Attention-grabbing blur effects at wider apertures

Use depth of field more creatively with spectacular but natural-looking background blur.

The rounded outline diaphragm of the lens is retained even when stopped down to f/5.6. Blur highlights in a photo reflect the shape of the aperture, and they are a much more prominent feature at wider apertures. Especially in higher-speed lens, this important optical design element results in more attractive, natural-looking images.

Other features

VCVibration Compensation

Stabilises camera blur for sharp images in low light

If you're shooting handheld when light is low, especially with longer lenses, your camera's shutter speeds can extend to a point where the image may turn out blurred due to camera shake. Tamron's VC tracks this shake and neutralises it for sharper images without the inconvenience of a tripod or the artificiality of a flash, in much lower light.

Tamron's unique VC mechanism uses a proprietary actuator and algorithms to deliver an extremely stable viewfinder image with excellent tracking. The tri-axial system uses three driving coils to move internal optical components within the VC lens electromagnetically, based on signals originating from three ball bearings, made from either steel or ceramic. The VC lens elements are held in place only by contact with the balls, achieving smooth movement with minimal friction.

Tamron's original moving magnet system employed a heavy magnet positioned near the moving VC lens element. The improved VC reverses the positions of magnet and coil and attaches the VC optic to the coil. This moving coil is lighter than the magnet, and as this reduces the load on the drive system, both the VC unit and the lens are lighter and more compact.

PZD - Piezo DrivePiezo Drive

Smaller, lighter, faster and highly accurate AF

Watch this feature in action on our YouTube channelAn exclusive Tamron innovation, the Piezo Drive (PZD) is an advanced ultrasonic autofocus (AF) motor based on the latest piezoelectric technology – the standing wave principle. High-frequency voltage turns a ceramic piezoelectric element with a swiveling motion, causing the metal tip at the rotor's contact point to rotate elliptically, thereby turning the rotor to focus the lens swiftly, silently, and with great precision.

Standing wave ultrasonic motors like the one used in Tamron's innovative PZD have a number of advantages. They're smaller and lighter and also provide faster and quieter operation than DC motors for improved AF performance. Compared with their predecessors, their actuator system allows far greater flexibility in lens design, reducing the overall size and weight of the lens.

Full-time manual focus

The full-time manual focus system enables fine focus adjustments to be made during autofocus shooting without having to change the focus mode beforehand.

Moisture-resistant construction for outdoor shooting

Moisture-resistant construction helps prevent moisture from penetrating the lens.

Flower-shaped hood is supplied with the lens to shield stray light

Included as a standard accessory, the flower-shaped hood matches the rectangular shape of the image sensor to most effectively block the interference of superfluous light rays entering from outside the borders of the image area, helping to ensure sharp, clear, flare-free images with crisp detail in the shadow areas.

Upgraded cosmetic design

Employing a sophisticated linear pattern rubber grip on the zoom and focus rings and an elegant tungsten silver brand ring, this newly-designed model accentuates its visceral presence with understated elegance and class.
