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.
Smaller, lighter, faster and highly accurate AF
An 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.
PZD autofocus is noticeably faster and quieter. Capture crisp images spontaneously, even in noise-sensitive situations. There is enhanced support for contrast-detection AF capabilities, and focusing when in live-view mode is smoother.
Full-time manual focus
Make fine focus adjustments at any time without having to switch out of autofocus mode.
Moisture-resistant construction helps prevent moisture from penetrating the lens.
Minimum focus distance of 39cm over the zoom range, with macro capability to 1:2.9
Designed exclusively for APS-C sized digital SLR cameras, this all-in-one zoom has a minimum focal distance of 0.39m (15.3 in.) through the entire zoom range. Macro capability down to 1:2.9 allows you to enjoy high-quality macro photography with astonishing convenience.
Elegant new design
The rubber grips on the zoom and focus rings have a rectilinear grid pattern that adds sophistication to the design, while the signature Tamron brand ring in tungsten silver enhances its luxurious finish.
- The Sony mount is not equipped with the VC image stabilisation mechanism, as the body of Sony’s digital SLR cameras has a built-in image stabilisation function. Consequently, the lens with a Sony mount is referred to as the 18-270mm F/3.5-6.3 Di II PZD and does not include the VC description.
- PZD (Piezo Drive) is a standing wave ultrasonic motor system developed by Tamron. The motor is faster and quieter than DC motors when the AF drive is operated, and compared with arc-type ultrasonic motors, it has an actuator that facilitates lens design and reduced size.
