Theia's standard focal range TL410 lens is designed for true 4K resolution.  This is the motorized version of the SL410 lens.  With varifocal length from 4-10mm and superior imaging performance, the TL410 can be used with image sensors from 1/2.3" up to 1/1.7".   It includes motors for zoom and focus, IR cut module, and limit indicators for zoom and focus ring positions (contact us for options with different motor configurations).  The lens is designed to be very compact so it can be used in small enclosures such as 4" domes and bullet style cameras.
