Optical camera lens assembly

An optical camera lens assembly, comprising:

• a lens group, comprising a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens arranged sequentially along an optical axis from an object side to an image side, wherein, each of the first lens, the fourth lens, and the sixth lens has a positive refractive power, and each of the second lens, the third lens, the fifth lens, and the seventh lens has a negative refractive power;
• and
• a plurality of spacing elements, comprising a third spacing element disposed between the third lens and the fourth lens and in contact with an image-side surface of the third lens;
• the optical camera lens assembly satisfies:
• 3.0<(R3+R4)/d3s<5.0,
• wherein, R3 is a radius of curvature of an object-side surface of the second lens, R4 is a radius of curvature of an image-side surface of the second lens, and d3s is an inner diameter of an object-side surface of the third spacing element,
• wherein the plurality of spacing elements further comprise a fourth spacing element disposed between the fourth lens and the fifth lens and in contact with an image-side surface of the fourth lens and a fifth spacing element disposed between the fifth lens and the sixth lens and in contact with an image-side surface of the fifth lens, and
• the optical camera lens assembly satisfies:
• 1.0<(EP45+CT5)/(T45+CP5)<2.5,
• wherein, EP45 is a spacing between the fourth spacing element and the fifth spacing element, CP5 is a maximum thickness of the fifth spacing element, CT5 is a center thickness of the fifth lens on the optical axis, and T45 is an air spacing between the fourth lens and the fifth lens on the optical axis.
