Camera lens

A camera lens consisting of, in an order 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 negative refractive power;
• wherein the camera lens satisfies following conditions (1-A)˜(3-A), and (5-A):
• 1.30≤f1/f≤1.40 (1-A);
• −2.00≤f4/f≤−0.90 (2);
• −2.00≤(R1+R2)/(R1−R2)≤−1.50 (3-A);
• 0.65≤f3/f≤0.75 (5-A);
• where,
• f:
• overall focal distance of the camera lens;
• f1:
• focal distance of the first lens;
• f3:
• focal distance of the third lens;
• f4:
• focal distance of the fourth lens;
• R1:
• curvature radius of the first lens' object side surface;
• R2:
• curvature radius of the first lens' image side surface.
