An inverted and diminished image is formed by the lens of the camera.
A camera lens is an optical lens or group of lenses used in combination with a camera body and mechanism to capture images of objects on photographic film or other media capable of chemically or electronically storing an image.
Uses of convex lens in cameras
Convex lenses are used widely in the camera, not only focus on an image but also to magnify it. Almost all lenses of cameras consist of a convex lens followed by a concave lens, followed by a second convex lens. The first lens controls the magnification level of the image by moving away from or towards the object.
