Size: 3MP1/2.7+650nm Definition 3MP 5MP Varifocal Lens M12 Mount for easy installation Adjustable focal length from 2.8mm to 12mm Wide aperture of F1.4 for low light performance to improve conversion rates Product overview This varifocal lens is built for definition imaging with compatibility for 3MP and 5MP systems. The compact M12 mount makes installation straightforward while the 2.8mm to 12mm adjustable focal length lets you tailor the field of view to the scene. A wide F1.4 aperture improves image brightness in low light conditions to capture clearer detail when illumination is limited. Key benefits Flexible framing and zoom control: Adjust focal length from 2.8mm to 12mm to switch easily between wide angle and telephoto views without changing the lens. Improved low light performance: F1.4 aperture gathers more light for brighter images and better detail in dim environments. Simple installation: Standard M12 mount provides straightforward attachment to compatible cameras and modules, reducing setup time. definition support: Designed for use with 3MP and 5MP imaging systems for sharper results and finer detail capture. Compact form factor: Small M12 lens footprint suits crowded camera housings and compact devices. Important attributes Function: Varifocal lens for adjustable field of view and focus control.
