PENTAX Unveils Varifocal Plus Lens

Security monitoring measures stand to improve a lot with the availability of these new Varifocal Plus lens. The new security lens offers a perfect solution to varifocal limitations with true 1.3 megapixel resolution and an installer-friendly design. With optical focus free technology, the PENTAX Varifocal Plus offers zoom lens maneuverability in a varifocal compact package.
The PENTAX Varifocal Plus is ideally matched for high resolution sensors on high-end security cameras. Optical performance is further enhanced with precise back focus adjustment, best suiting this lens for board cameras with a back focus that may be factory pre-adjusted. The Varifocal Plus is a perfect solution for varifocal limitations, high-resolution and high-sensitivity needs. The PENTAX Varifocal Plus lens helps meet the needs of more precise and timesaving CCTV installation through consistent focus technology.
This new technology’s essential advantage over the competition is the capability of maintaining clear focus in all zooming ranges of the focal length variance. Conventional varifocal lenses have a common disadvantage of losing focus track as the focal length changes. This PENTAX Varifocal Plus lens offers focus-free technology to capture images of objects up close and at a distance with very small distortion or need for refocusing.
The fundamental difference of this new product is the capacity for tracking with clear focus as the focal length of the lens changes. PENTAX’s Varifocal Plus helps eliminate defocusing problems in crucial installation sites. The necessity of re-adjusting the focus, with focal length or zoom range variation, is an additional cost as well as a great inconvenience for installers.
With an innovative focus and zoom interlocking mechanism, the PENTAX Varifocal Plus provides a solution for the problem of total defocusing in zooming due to the independent moves of the focus and zoom lens groups that is found in conventional varifocal lenses.
The PENTAX Varifocal Plus lens will be displayed at the International Security Conference & Exposition (ISC WEST) from April 1-3, 2009 in Las Vegas. The lens will ship in 2009 at a price to be announced.
