The Pentax Varifocal Lens 5-50 mm is recommended for use with the AXIS 211 and AXIS 211A Network Cameras. The lens can also be combined with the AXIS 221 Network Camera, but offers less magnifying power. The lens is not day/night corrected and will therefore need adjustment when the AXIS 221 IR-cut filter disengages. FEATURES: 50 mm setting for... Less
