Camera Device

A camera device comprising:

• a plurality of lenses;
• and
• an annular body having a fixed hole;
• wherein the plurality of lenses and the annular body are arranged between an object side and an image side along an optical axis;
• wherein the annular body is disposed between the object side and the plurality of lenses, between the plurality of lenses, or between the plurality of lenses and the image side;
• wherein the annular body comprises an annular main body, an outer circumferential portion, and an inner circumferential portion, wherein the annular main body connects to the outer circumferential portion and the inner circumferential portion, the annular main body is disposed between the outer circumferential portion and the inner circumferential portion, and the inner circumferential portion is non-circular and surrounds the optical axis to form the fixed hole;
• wherein the camera device satisfies:
• EFL/√{square root over (4A/π)}=(EFL/Dx×EFL/Dy)×K2;
• K2<1/(EFL/√{square root over (4A/π)})−0.01;
• wherein EFL is an effective focal length of the camera device, A is an area of the fixed hole, K2 is a constant, Dx is a maximum dimension of the fixed hole through which the optical axis passes, and Dy is a minimum dimension of the fixed hole through which the optical axis passes.
