(discontinued) Mega-Pixel Lens (Vari-Focal)

This product has been discontinued. For a replacement, please see the Tamron M13VM288IR

The Tamron M13-VM308 is a mega-pixel vari-focal lens with a manual iris. Each lens in Tamron's Mega-Pixel-Compatible Vari-Focal Lens series uses hybrid aspherical elements (and special glass elements in the case of the 3.0-8mm lens) to minimize various optical aberrations and ensure high optical quality while realizing the compact design. Through the employment of innovative optical technologies, each lens delivers high-resolution and high-contrast images that are uniformly sharp from the center to the periphery.

In particular, resolution in the image corner is almost double when compared to that of conventional lenses. Each lens provides the best solution in applications with high quality mega-pixel cameras, ensuring high quality images even when images are enlarged.

Multicoating is applied to lens surfaces to minimize the phenomena of ghosting and flare in backlit situations. The result is consistent high contrast and excellent image quality even in such conditions. Each and every mechanical component boasts high accuracy and is assembled with advanced manufacturing engineering technologies. As s result, constructional problems that are likely to cause image degradation through focal point shift or lopsided blur have been eliminated.

The M13 VM308 features a 3.0 - 8mm focal length and an aperture range of 1.0 - Close. Tamron ’s Mega-Pixel-Compatible Van-Focal Lens Series covers a wide range of angles of view from 2.4mm ultra wide-angle, 8mm standard focal length and even 50mm ultra telephoto in order to satisfy all needs. Each lens features a lightweight and compact design to fit almost all surveillance applications. Each control ring (zooming, focusing and iris-control*) has a lock mechanism. Setting displacement after installation can be avoided since each ring can be independently locked. (*Manual iris only)

Each lens is equipped with a slip-mount mechanism that allows position adjustment by rotating the lens after it is mounted on a camera. This facilitates setting the auto-iris meter portion of the lens to a correct position around the lens.

Environmentally-friendly designs are used, including the employment of design approaches that do not use substances in optical glass materials, sealing and packaging that impact the environment. In addition, each Tamron factory implements environmental assessment when procuring materials and components in order to ensure non-use of environmentally destructive substances.

The M13VM308 is a fast lens boasting the maximum aperture of Ff1.0. The extremely fast maximum aperture enhances the sensitivity of surveillance cameras, making it possible to obtain vivid color images even in dimly-lit conditions such as dark rooms, corridors, or during surveillance in early morning or evening hours when sufficient light is not available. The fast lens is especially useful for cameras equipped with low sensitivity image sensors since it enhances light intensity.
