During zooming from the wide angle end to the telephoto end, the second lens unit moves closer to the first lens unit only toward the object side, the third lens unit moves in such a way that it becomes closest to the second lens unit at an intermediate focal length position in the course of zooming as compared to the state at the wide angle end and the state at the telephoto end, and the fourth lens unit moves. The zoom lens satisfies a certain condition.

The image forming optical system includes at least a lens unit nearest to object side which is disposed nearest to an object side, an aperture stop which is disposed on an image side than the lens unit nearest to object side, and an image-side lens unit which is disposed on the image side than the aperture stop. The lens unit nearest to object side includes a lens having a mark formed on an effective area of a lens surface thereof. At least any one of the lens in the image forming optical system is held such that, a shifting or a tilting of the lens can be adjusted. The electronic image pickup apparatus further includes a correction parameter storage section which stores correction parameters for correcting an unevenness of brightness due to the mark, and a signal processing section which corrects the unevenness of brightness due to the mark of which, an image has been picked up by the image pickup element, based on the correction parameter stored in the correction parameter storage section.
