1. An imaging lens system, comprising:
a total of seven lenses including a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens comprising a convex image-side surface, and a seventh lens disposed in order from an object side with a gap disposed along the optical axis between each set of adjacent lenses; and
a stop disposed on an image side of one of the first to sixth lenses,
wherein the first lens has negative refractive power,
wherein the third lens has positive refractive power, and
wherein one or more of the second to seventh lenses, disposed on an image side of the stop, each has a positive refractive power and a negative refractive index temperature coefficient.
