When a camera needs more than a fixed focal length, the SLA-M2890PN gives installers the range to frame the scene correctly from the start. Its 2.8-9.0 mm varifocal design supports everything from wider coverage to tighter subject focus, making it a practical choice for entrances, corridors, lobbies, and perimeter views where scene geometry changes from site to site. Built for 1/2.8-inch sensors and rated for 3 MP imaging, this lens is matched to surveillance systems that need usable detail without overcomplicating the installation. The auto P iris helps regulate light across changing conditions, supporting more consistent exposure as ambient light shifts during the day. CS-mount compatibility keeps integration straightforward for supported camera housings. For security teams and integrators, the value is in precision. A varifocal lens reduces guesswork during commissioning and helps avoid the compromises that come with fixed lenses. In deployments where image framing, exposure control, and sensor match matter, the SLA-M2890PN is built to do the job cleanly.
