Camera Lens

A camera lens comprising, arranged sequentially from an object side to an image side:

• a first lens with positive refractive power;
• a second lens with negative refractive power;
• a third lens with positive refractive power;
• a fourth lens with positive refractive power;
• a fifth lens with negative refractive power;
• wherein the camera lens satisfies the following conditions (1)˜(5):
• 0.65≦f1/f≦0.75 (1)
• −1.40≦f2/f≦−1.25 (2)
• 10.00≦f3/f≦24.00 (3)
• −1.20≦(R1+R2)/(R1−R2)≦−1.00 (4)
• 1.00≦(R3+R4)/(R3−R4)≦2.00 (5)
• where,
• f:
• overall focal distance of the camera lens;
• f1:
• focal distance of the first lens;
• f2:
• focal distance of the second lens;
• f3:
• focal distance of the third lens;
• R1:
• curvature radius of the first lens' object side surface;
• R2:
• curvature radius of the first lens' image side surface;
• R3:
• curvature radius of the second lens' object side surface;
• R4:
• curvature radius of the second lens' image side surface.
