<P>PROBLEM TO BE SOLVED: To provide a photometric device and a camera in which the chromatic aberrations are corrected properly. <P>SOLUTION: A photometric device includes a photometric sensor 14, a photometric optical system 15 that guides light to the photometric sensor 14, and a lens barrel member 24 that supports the photometric optical system 15. The photometric optical system 15 includes a first optical member 20 having a fixed position with respect to the photometric sensor 14, and a second optical member 22 including a diffraction optical element 21, and the second optical member 22 is held between the lens barrel member 24 and the first optical member 20. <P>COPYRIGHT: (C)2013,JPO&INPIT |
