Abstract:
A camera assembly, sequentially comprising from an object side to an image side: a first lens group which has positive focal power and a second lens group which has positive focal power, an aperture being arranged between the first lens group and the second lens group. The first lens group sequentially comprises along the object side to the image side: a first lens which has a negative refractive index; a second lens which has a negative refractive index; a third lens which has a negative refractive index; and a fourth lens which has a positive refractive index. The second lens group sequentially comprises along the object side to the image side: a fifth lens which has a positive refractive index; a sixth lens which has a negative refractive index; and a seventh lens which has a positive refractive index. The first lens and the fourth lens are made of glass, and the other lenses are made of plastic. The field of view of the camera assembly is 180°≤FOV≤220°. In addition, the present invention further provides an image capture apparatus and a movable platform.
