Optical lens assembly, image capturing apparatus and electronic device

An optical lens assembly comprising seven lens elements, the seven lens elements being, in order from an object side to an image side:

• a first lens element with positive refractive power having an object-side surface being convex in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof;
• a second lens element with negative refractive power having an object-side surface being convex in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof;
• a third lens element;
• a fourth lens element having an object-side surface being convex in a paraxial region thereof;
• a fifth lens element;
• a sixth lens element;
• and
• a seventh lens element having an image-side surface being concave in a paraxial region thereof, wherein an object-side surface and the image-side surface of the seventh lens element are aspheric, and the image-side surface of the seventh lens element comprises at least one convex shape in an off-axis region thereof;
• wherein the optical lens assembly has a total of seven lens elements, an absolute value of a focal length of the first lens element is smaller than an absolute value of a focal length of the fifth lens element and an absolute value of a focal length of the sixth lens element, an axial distance between the fourth lens element and the fifth lens element is greater than an axial distance between the second lens element and the third lens element, a focal length of the optical lens assembly is f, a composite focal length of the third lens element, the fourth lens element and the fifth lens element is f345, and the following condition is satisfied:
• 0<f/f345<1.0.
