PROBLEM TO BE SOLVED: To provide a small size and clear imaging lens system and an imaging apparatus at a low cost.SOLUTION: An imaging lens system 11 in an embodiment, includes: from the object side in order, a first lens L1 which is a plano-convex lens having a convex surface and which has a positive power at the object side; a second lens L2 which is a meniscus lens having a concave surface at the object side and which has a positive power; and a third lens L3 which has a convex shape at the object side. An imaging apparatus 10 in an embodiment includes: the imaging lens system 11; an image pick-up device 14 which is disposed at a focus position of the imaging lens system 11; and a band-pass filter 12 disposed between the imaging lens system 11 and the image pick-up device 14.SELECTED DRAWING: Figure 5 |
