The Tamron 13VM550ASII CCTV Lens (5-50mm, f/1.4) is suitable for cameras having an imager size of 1/3". An aperture range of f/1.4-close allows for clear images in low light conditions.
The CCTV lens has hybrid aspherical elements that reduce various optical aberrations, delivering high optical quality. When used with digital recording systems, the lens provides improved resolution at corners. It features manual iris, focus, and zoom with lock, a focus range of 0.3m and back focus in air of 10.5mm (wide) to 11.81mm (tele). Multi-coating on lens surface lessens ghosting and flare in backlit conditions. The 13VM550ASII CCTV lens, with enhanced proprietary ND filter, ensures high resolution from maximum aperture to minimum aperture.
A slip-mount mechanism allows you to fine-tune the position after mounting the camera to set the auto-iris meter to a proper position around the lens. With the lock for each control ring (zoom, manual, and iris-control), you can avoid setting displacement after installation. The CS mount makes the 13VM550ASII CCTV lens suitable for mini domes.
The CCTV lens operates in a temperature range of -20 to 60°C and is appropriate for security applications where high resolution and/or short-to-medium long-range focal points are required.
