1. An imaging apparatus, comprising:
two imaging optical systems including:
a first imaging optical system; and
a second imaging optical system;
two image sensors, disposed with back faces of the two image sensors facing each other, including:
a first image sensor to capture a first image formed by the first imaging optical system; and
a second image sensor to capture a second image formed by the second imaging optical system:
two holders including:
a first holder to hold the first image optical system and the first sensor; and
a second holder to hold the second image optical system and the second image sensor; and
a fixing structure to fixing the two holders together,
wherein the first holder and the second holder being symmetrically combined to form a composite barrel in a front-to-back direction, each of the first holder and the second holder has the same structure;
wherein the first holder including:
a first lens positioner to set a position of a lens constituting the first imaging optical system; and
a first contact disposed apart from the first lens positioner, and
the second holder including:
a second lens positioner to set a position of a lens constituting the second imaging optical system; and
a second contact disposed apart from the second lens positioner, and
wherein, with the two holders fixed together by the fixing structure, the first contact of the first holder directly contacts the second contact of the second holder with the lens maintained at the position set by the first lens positioner of the first holder and the second lens positioner of the second holder.
