Compact image pickup lens

An image pickup lens, in order from an object side to an image side along an optical axis thereof, comprising:

• a first lens element of positive refractive power, the first lens element having a meniscus shape and an object-side surface convex toward the object side;
• a second lens element of positive refractive power, the second lens element having a meniscus shape and an image-side surface convex toward the image side;
• an aperture positioned between the first and second lens elements;
• and
• a third lens element of negative refractive power, the third lens element having an aspheric surface on the image side;
• wherein, the first, second and third lens elements satisfy the following conditions:
