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 14):
The image pickup apparatus according to  claim 7 , wherein the following expression is satisfied:\n \u22120.4< Lo/Ls< 0.4, where Lo represents a distance from a paraxial object point position of the optical system to a vertex of a surface on the image side of a lens having a strongest negative refractive power within the optical system, wherein the lens having the strongest negative refractive power within the optical system which is proximate to the paraxial object point position of the optical system comprises one of a single lens or a cemented lens.
