Photographing optical lens assembly, imaging apparatus and electronic device

A photographing 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, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element and a seventh lens element;
• wherein the first lens element has positive refractive power, the second lens element has positive refractive power, the sixth lens element with positive refractive power has an image-side surface being convex in a paraxial region thereof, and the seventh lens element has an image-side surface being concave in a paraxial region thereof and comprising at least one convex critical point in an off-axis region thereof;
• wherein a curvature radius of an object-side surface of the sixth lens element is R11, a curvature radius of the image-side surface of the sixth lens element is R12, a total number of the lens elements having Abbe numbers less than 20 is V20, and the following conditions are satisfied:
• 0<(R11+R12)/(R11−R12)<4.0;
• and
• 1≤V20.
