Claim:
A magnifying attachment which is attached to and used with a camera having a camera lens, for magnifying an image to be taken by the camera, the magnifying attachment comprising: a main body which is detachably fixed to the camera; an objective lens which is fitted with the main body; a converging lens which is fitted with the main body, wherein the objective lens allows an image light from an object to be imaged to pass therethrough to magnify the image light, and wherein the converging lens allows the image light that has passed through the objective lens to pass therethrough to converge the passed image light on a pupil of the camera lens of the camera with a solid angle that is substantially equal to or larger than a viewing angle of the camera lens, when the main body is fitted with the camera; and a field lens that is fitted with the main body, wherein the field lens allows the image light that has passed through the objective lens to pass therethrough to adjust the passed image light so as to enter the entire converging lens, and wherein the converging lens allows the image light that has passed through the field lens to pass therethrough to converge the passed image light on the pupil of the camera lens with a solid angle that is substantially equal to or larger than a viewing angle of the camera lens, when the main body is fitted with the camera, and wherein the main body is equipped with an aperture that narrows the image light to deepen a focal depth when the main body is fitted with the camera.
