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 fifth lens element with negative refractive power has an image-side surface being concave in a paraxial region thereof;
• the sixth lens element 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 the image-side surface of the seventh lens element comprises at least one convex critical point in an off-axis region thereof;
• wherein an Abbe number of the fourth lens element is V4, an Abbe number of the fifth lens element is V5, a focal length of the photographing optical lens assembly is f, a focal length of the fifth lens element is f5, and the following conditions are satisfied:
• V4+V5<70;
• and
• f/f5≤−0.25.
