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 13):
The image pickup apparatus according to  claim 7 ,\n wherein the lens of the optical system that is closest to the object side comprises a lens having a negative refractive power, and wherein the following expression is satisfied:\n 0.01<| r 2/ r 1|<0.9, \n where r1 and r2 represent curvature radii of the negative lens on the object side and on the image side, respectively,\n wherein the lens of the optical system that is closest to the object side comprises one of a single lens or a cemented lens.
