Product Overview

Tamron teleconverters provide powerful and creative options for your telephoto photography. A Tamron teleconverter mounted between the lens and the camera body increases the focal length of the host lens, providing greater magnification from the same camera position. Tamron's teleconverters are compatible with most (autofocus) and auto-exposure cameras.

Technology

CLICK to view all of the different technologies in Tamron lenses. Below are a few that can be found in the Tamron lens line.
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.

The 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 One -Year Limited Warranty in the case of teleconverters, the only warranty accepted by Tamron USA, Inc. in the USA as of October 1, 2007.
