Tamron Variable Focus Camera Lenses

A variable focus camera lens(vari-focal) enables you to adjust not only the focal length but also the angle of view and the level of zoom. This is different than standard zoom lenses, which remain in focus as the lens zooms in. Also referred to as varifocal lenses, these lenses are well suited for surveillance cameras in addition to a variety of other commercial and industrial uses.

The main benefit of a variable focus industrial camera lens(vari-focal) is the ability to adjust it to find the perfect field of view. Once the field has been set, it stays the same until you need to adjust it again. This adaptability is crucial to meeting very specific surveillance needs. Whether you need to keep close eyes on an access point or a wide view of a large space, these varifocal camera lenses can do it all.

At Tamron, we make it easy to find the right lens you need for your intended network surveillance application. Here, you can find manual iris, DC auto iris, and P iris variable focus camera lenses with varying imager sizes, focal lengths, and aperture ranges. No matter what kind of variable focus camera lens (vari-focal) you need, we have a solution.

There are many reasons why you may want a variable focus industrial camera lens(vari-focal) instead of a fixed camera lens. If you don’t know the specific field of view required for an application, a variable focus lens would be a smart choice because you can always adjust the lens to get the view you want. These kinds of lenses also offer unmatched long-term flexibility, so if your use of a system or needs change over time, the varifocal needs can adapt reliably. Lastly, a variable focus camera lens(vari-focal) offers much sharper and clearer image quality, as it allows you to focus on areas of interest and use the full resolution of the camera to produce an exceptionally high-quality image.
