    Abstract: Provided are an imaging lens that has a small amount of focus shift caused by temperature fluctuation and an imaging apparatus that has this imaging lens. The imaging lens consists of, in order from an object side: a first lens that is convex toward the object side and has a negative refractive power; a second lens that has a negative refractive power; a third lens that has a positive refractive power; a fourth lens that has a positive refractive power; a fifth lens that has a positive refractive power; and a sixth lens that has a negative refractive power. The imaging lens satisfies the following conditional expressions (1) to (4). −0.89

    Abstract: A radiation image capturing system includes a first image capturing apparatus for capturing a radiation image of a subject, a second image capturing apparatus for capturing a radiation image of the subject, the second image capturing apparatus having a specification different from that of the first image capturing apparatus, an image correcting device for correcting the radiation image of the subject which is captured by the second image capturing apparatus such that the radiation image of the subject which is captured by the second image capturing apparatus has the same magnification as that of the radiation image of the subject which is captured by the first image capturing apparatus, and a display unit for displaying the corrected radiation image. The radiation images captured by the image capturing apparatus of different specifications are corrected to have the same magnification.
