A vehicular vision system includes a camera configured to be disposed behind a windshield of a vehicle so as to have a field of view exterior of the vehicle through the windshield. The camera includes a primary lens, a secondary lens, and an imager, which includes a primary sensing area and a secondary sensing area. The primary sensing area captures image data representative of images focused at the imager by the primary lens and the secondary sensing area captures image data representative of images focused at the imager by the secondary lens. The secondary lens is between the primary lens and the imager. A control includes a processor that processes image data captured by the imager at the primary sensing area and at the secondary sensing area. The control, responsive to processing of image data captured at the secondary sensing area, determines presence of water droplets at the windshield.
