Theia's SL1250 lens is designed to be very compact and better image performance compared to competitive products.  Despite the long focal telephoto focal length, this lens is designed for small 4" dome cameras and bullet cameras.  

Similar to Theia's other lenses, the SL1250 series is a high quality lens designed to allow the installer to take full advantage of the high resolution of 4K resolution, HD, and multi megapixel cameras.  The lens can be used on cameras up to 12 megapixel resolution giving a crisp image from edge to edge.  

The motorized version of the lens is the TL1250.
