Claim 11:
12. A camera lens group, sequentially from an object side to an image side of the camera lens group along an optical axis, comprising:
a first lens having refractive power;
a first prism having a first reflecting surface, and an angle between the first reflecting surface and the optical axis being 45°;
a stop;
a second lens having refractive power;
a third lens having refractive power;
a fourth lens having refractive power;
a second prism having a second reflecting surface, and an angle between the second reflecting surface and the optical axis being 45°; and
a fifth lens having refractive power,
wherein 2.00 mm<ImgH/tan2(Semi-FOV)<4.00 mm,
where Semi-FOV is half of a maximum field-of-view of the camera lens group, and ImgH is half of a diagonal length of an effective pixel area on an imaging plane of the camera lens group; and
wherein a total number of lenses in the camera lens group is five and a total number of prisms in the camera lens group is two.
