Product Details

This is the perfect allsky lens for most allsky cameras and specially apt for 1/2" sensor size cameras. With the CS mount and built-in IR correction, this lens will give you a 185 degree Field of View. Very light sensitive at F2 and rated for 5MP this lens will give you a 4.7mm image circle on your sensor.

With 1/2" sensor cameras you will have a full image circle. With 1/3" sensor cameras the top and bottom of the image circle will be cut, as you can observe in the picture attached.

Focal Length	1.55mm
HFOV	185°

For sensor size	1/2"
