Abstract
The object of this invention is to provide a magnifying attachment to be attached to a camera by which a high magnification image can be obtained without appearing a part having no image in the image. The magnifying attachment has a magnifying objective lens (21A), a field lens (21B) for converting a light passed through the objective lens (21A) into collimated light, and a converging lens (21C) for focusing the collimated light on a camera lens (42). Light passed through the converging lens (21C) is converged on a pupil (42X) of the camera lens (42) with a solid angle exceeding the view angle of the camera lens (42).
