An optical system comprising:
- first to fifth lenses sequentially disposed from an object side,
- wherein a composite power of the first lens and the second lens is negative,
- wherein a composite power of the third to fifth lenses is positive,
- wherein an effective diameter of the second lens among effective diameters of the first to fifth lenses is a smallest,
- wherein the effective diameter of the first lens is larger than an effective diameter of the second lens and smaller than the effective diameters of the third to fifth lenses,
- wherein a power of the third lens among powers of the first to fifth lenses is a largest, and
- wherein the power of the fourth lens among the powers of the first to fifth lenses is the second largest.
An optical system comprising:
- first to fifth lenses sequentially disposed from an object side,
- wherein each of the first to fifth lenses has an object-side surface and a sensor-side surface,
- wherein a composite power of the first lens and the second lens is negative,
- wherein a composite power of the third to fifth lenses is positive,
- wherein an effective diameter of the second lens among effective diameters the first to fifth lenses is a smallest,
- wherein a power of the third lens among powers of the first to fifth lenses is a largest, and
- wherein an optical axis distance from the object-side surface of the first lens to the sensor-side surface of the second lens is in a range of 26% to 36% of an optical axis distance from the object-side surface of the third lens to the sensor-side surface of the fifth lens.
An optical system comprising:
- first to fifth lenses sequentially disposed from an object side;
- and
- an aperture stop disposed on a periphery between the first lens and the second lens,
- wherein an effective diameter of the second lens among effective diameters of the first to fifth lenses is a smallest,
- wherein a power of the third lens is positive and has a largest among powers of the first to fifth lenses, and
- wherein the power of the fourth lens is positive and greater than the powers of the first, second, and fifth lenses.
