This high quality lens allows the installer to take full advantage of the high resolution of HD and multi megapixel cameras. The lens can be used on cameras up to 5 megapixel resolution. The SL183 and ML183 includes EasyZoom? which allows the installer to focus the lens once and then adjust zoom or magnification to give the optimized field of view.
