Patent ID: 12001081

Abstract:
The present invention relates to a field of optical lens, and provides a camera optical lens including, from an object side to an image side in sequence: a first lens having a negative refractive power, a second lens having a positive refractive power, a third lens, a fourth lens having a negative refractive power, a fifth lens having a positive refractive power, a sixth lens, a seventh lens having a negative refractive power and provided with an image-side surface as a free-form surface; and the camera optical lens satisfies conditions of: |f2/f3|≤0.07; −0.50≤f2/f4≤−0.30; 0.58≤D12/f≤0.64; and 0.35≤D23/f≤0.45. The camera optical lens provided by the present disclosure has |TV_D|<1.0%, has excellent optical performance, is of wide angle with 2ω>110°, and includes seven lenses.
