Product Overview

Tamron innovation yielded the world's highest ratio wide-to-telephoto zoom. Featuring an incredible zoom range of 15x, the 18-270mm Di-II VC defines compositional versatility. Providing a 35mm wide-angle picture angle equivalent of 28mm to an astounding 419mm, image fidelity is assured in two ways. First; award-winning optical design leverages the benefits of LD glass and aspherical optics, rendering crisp and faithful images, while Tamron's unique tri-axial VC (Vibration Compensation) combats image blur caused by camera movement. Improving sharpness at typical shutter speeds and enabling handheld shooting at as many as four shutter speeds slower than would otherwise be possible, Tamron's three pairs of driving coils and low-function ball bearings placed around the VC optical group provide unsurpassed image stabilization for sharper images and a dramatically stable viewfinder experience.

Di-II lenses are performance-engineered expressly for digital SLR cameras with image sensors commonly referred to as APS-C, measuring approximately 24mm x 16mm.

Recommended for APS-C photographers who…

- Demand the pinnacle in all-in-one zoom versatility and image performance.
- Need even more subject magnification—expanding sports, nature and wildlife picture opportunities.
- Appreciate the mobility of handheld shooting, but reject the image blur that it often introduces.
- Want fewer lens changes, reducing instances of exposing the DSLR sensor to image-degrading dust, or missing the shot.
- Want image quality far exceeding typical kit lens capabilities.

Tamron Di-II lenses are engineered expressly for digital SLR cameras with image sensors commonly referred to as APS-C, measuring approximately 24mm x 16mm. Rendering an ideal image circle for APS-C sensors, Di-II lenses also include properties to optimize digital imaging performance. Rely on Tamron Di lenses for use with DSLRs featuring larger full frame (36mm x 24mm) sensors or 35mm film SLRs.

Technology

Di II Tamron Di-II lenses are engineered expressly for digital SLR cameras* with image sensors commonly referred to as APS-C, measuring approximately 24mm x 16mm. Rendering an ideal image circle for APS-C sensors, Di-II lenses are also include properties to optimize digital imaging performance.
Vibration Compensation

Tamron’s Unique State-of-the-Art In-Lens Image Stabilization System
Handheld camera shake is the leading cause of blurry and unsharp pictures. Several leading companies now make lenses with built-in optical image-stabilization systems that sense the amplitude and direction of the shake and compensate by moving optical groups within the lens. Tamron’s exclusive new Vibration Compensation (VC) system that’s built into the Tamron AF28-300mm F/3.5-6.3 XR Di VC LD Aspherical (IF) Macro and the Tamron AF18-270mm F/3.5-6.3 Di-II VC LD Aspherical (IF) Macro lenses performs a similar function, but it executes it much more effectively due to its innovative breakthrough design.

AD

Anomalous Dispersion (AD) for Better Color Correction
Anomalous dispersion (AD) glass is a special type of optical glass that is used to achieve more precise control of chromatic aberrations, thereby enhancing overall imaging performance. Glass of this type provides an abnormally large partial dispersion ratio (amount of diffraction) for light of specific wavelength ranges (colors) within the visible spectrum. By combining AD glass having these special characteristics with elements made of normal glass having different dispersion characteristics, it is possible to control the dispersion factors of a specific wavelength. This enhanced level of control results in much lower levels of on-axis (central) chromatic aberration for telephoto lenses (or zooms used at tele-photo settings) and a significant reduction of lateral (peripheral) chromatic aber-ration for wide-angle lenses (or zooms used at wide-angle settings.)

Low Dispersion

Low Dispersion (LD) Glass for Greater Lens Sharpness
Low dispersion (LD) glass elements in a lens help reduce chromatic aberration; the tendency of light of different colors to come to different points of focus at the image plane. Chromatic aberration reduces the sharpness of an image, but glass with an extremely lowdispersion index, has less of a tendency to separate (defract) a ray of light into a rainbow of colors. This characteristic allows the lens designer to effectively compensate for chromatic aberration at the center of the field (on axis), a particular problem at long focal lengths (the telephoto end of the zoom range), and for lateral chromatic aberration (towards the edges of the field) that often occurs at short focal lengths (the wide-angle end of the zoom range.)

Aspherical

Hybrid Aspherical Elements Provide the Ultimate in Image Quality and Compactness
Tamron uses several hybrid aspherical lens elements in many lenses bearing the Aspherical designation. These innovative optics allow us to achieve the ultimate in image quality, and at the same time produce lenses that offer remarkable zoom ranges in extraordinarily compact packages. By perfecting theses cutting-edge advances for series production, Tamron has advanced the state of optical design, and virtually eliminated spherical aberration and image distortion from the high-power-zoom series.Through the effective application of Hybrid Aspherical Technology, one lens elemen tcan take the place of multiple elements without compromising performance. This is what allows us to produce remarkably compact long-range lenses that deliver a uniformly high level of image quality at all focal lengths and apertures.

Internal Focusing

Internal Focusing (IF) System
Internal focusing (IF) provides numerous practical benefits to photographers including a non-rotating front filter ring that facilitates the positioning of polarizing and graduated filters, and more predictable handling because the lens length does not change during focusing. Even more important, Tamron’s Internal Focusing (IF) system provides a much closer minimum focusing distance (MFD) throughout its entire focusing range. In addition, IF improves optical performance by minimizing illumination loss at the corners of the image field, and helps to suppress other aberrations that become more troublesome at different focusing positions.

Zoom Lock

Zoom Lock (ZL) Feature
Another original Tamron mechanical engineering concept is the Zoom Lock (ZL), a simple convenience feature that prevents undesired extension of the lens barrel when carrying the camera/lens unit on a neck strap.

he Risk of Purchasing Gray Market Products:
In looking for our products, you may find that products not supplied through our regular channel are sold in your market. Such products are generally called “gray-market products” and may involve quality problems.

Interchangeable lenses are precision optical and mechanical products. Therefore, if handling during transportation or storage is not adequate, defects or malfunctions may occur. As for our products supplied through our regular distribution channel, meticulous care is taken in transportation and storage in order to ensure quality protection. However, in the case of gray-market products, it is more likely that they are handled inadequately during transportation or storage; are exposed to undesirable conditions such as high temperatures, vibration, shock, high humidity, dust, dirt and so on; or that they have been mixed up with used products since they are not under our strict control. Therefore, we are unable to warrant the quality of gray-market products.

Always look for Tamron products that are supplied through our authorized distribution channel. By purchasing Tamron products from an authorized dealer, you can ensure the quality of the product, which will be also covered by Tamron USA's Six-Year Limited Warranty, the only warranty accepted by Tamron USA, Inc. in the USA as of October 1, 2007.
