Tamron announces the launch of
A New 5-Mega-Pixel NIR (Near-IR) Vari-Focal Lens

1/1.8” 12-50mm F/1.4 (Model: M118VG1250IR)

February 23, 2016, Saitama, Japan – Tamron Co., Ltd., (President & CEO Morio Ono), an integrated optics manufacturer and leader in the security/surveillance equipment industry, announces the release of a 1/1.8” 12-50mm F/1.4 5-mega-pixel NIR Vari-Focal Lens (Model: M118VG1250IR).

Demand for IP/network cameras is growing at an unprecedented speed in the security market. Today’s requirement for high image-quality mandated resolution higher than 5-mega-pixel / Full HD 1080P.

To address the market need, Tamron has released a ‘Double Vari-Focal’ lens system, a complementary lens-pair solution that powerfully supports major security applications: an M13VG288IR (f=2.8-8mm) lens and an M13VG850IR (f=8-50mm) lens to seamlessly cover the entire focal length range from the wide-angle f=2.8mm to the telephoto-end f=50mm. Because of the universal angular field of view coverage being addressed between the two, the solution has received exceptionally high recognition in the market.
Demand for large-size 1/1.8” and 1/2” imagers has also grown prominently for surveillance installations in highly populated urban areas, where distinguished resolving power becomes critically important to make the most of the imaging capabilities of 5-megapixel sensors. A new lens, M118VG1250IR, now released by Tamron, specifically addresses the needs in the surveillance market.

Tamron, as an integrated optics manufacturer, progressively pursues development of such high-quality and innovative products.


  • NIR Lens Covering Focal Lengths Most Universally Utilized in Telephoto Applications
  • The new lens delivers high-quality images throughout the most commonly used focal length range of 12-50mm. Expanding the spectrum coverage to NIR region, the lens enhances and assures high-precision and high-efficiency day-and-night surveillance.

  • High-Quality NIR Imaging
  • An ideal lens for day-and-night mega-pixel surveillance with chromatic aberrations well compensated for delivers improved performance in the NIR bandwidth and well-tuned image quality from corner to corner. Tamron’s proprietary optical design with an optimal choice of glass materials backed by high-precision process technology brings an ideal balance in performance to cost.

  • Discrete Optical Design Considering Low-Light Conditions
  • The image circle diameter is expanded to permit compatibility with 1/1.8” imagers widely adopted in the security/surveillance market. A fast aperture of F/1.4 is achieved by a new optical design, while the minimum aperture stops down to F/360. The new lens is also compatible with 1/2” and 1/3”imagers.

  • Substantial Reduction of Flare and Ghosting
  • The performance of the new lens has gone through extensive validation processes using state-of-the-art simulation, weighed heavily on specific conditions of a wide variety of surveillance scenes. Disturbing flare and ghosting are attenuated to the minimum and Tamron’s proprietary multi-coating technology is employed to thoroughly reducing flare and ghosting.

  • Pursuit of High Utility and High Reliability
  • In line with Tamron’s product development philosophy for high reliability, proprietary knowledge and manufacturing know-hows have been extensively utilized for the design and manufacturing of the new lens, M118VG1250IR, similar with other Tamron products.
    ・Large rotation angle for faster and easier focusing
    ・Slip-mount mechanism for faster and easier camera / lens installation and assembly
    ・Highly-reliable auto iris mechanism
