Abstract:
An image pickup apparatus includes: a mount to which an interchangeable lens is mountable; an image sensor; an optical system having a refractive power and imaging an object point located on an image side of a most-object-side surface of the optical system onto the image sensor; and an optical filter arranged between the optical system and the image sensor, and a distance on an optical axis from a flange surface of the mount to the object point located on the image side of the most-object-side surface, a distance on the optical axis from the flange surface of the mount to the image pickup element, and a lateral magnification of the optical system when the interchangeable lens is mounted to the image pickup apparatus and the object point located on the image side of the most-object-side surface, is imaged onto the image pickup element, are appropriately set.

Claim (Index 6):
The image pickup apparatus according to  claim 5 ,\n wherein the optical system includes a first lens unit which consists of three lenses from the object side, the following expressions are satisfied:\n 1.8< n 1 av ; and \n 5< v 1 n\u2212v 1 p< 20, \n where n1av represents an average refractive index of the negative lenses included in the first lens unit, v1n represents an average Abbe number of the negative lenses, and v1p represents an Abbe number of the positive lens included in the first lens unit.
