Title
(EN) PHOTOGRAPHIC LENS AND PHOTOGRAPHIC APPARATUS COMPRISING SAME
(KO) 촬영 렌즈 및 이를 포함하는 촬영 장치
Abstract
(EN)
The present invention relates to a photographic lens and a photographic apparatus comprising the same. The photographic lens is in a sequence from an object to an image plane, and comprises: a first lens having positive or negative refractive power; a second lens having positive or negative refractive power; a third lens having positive refractive power; a fourth lens having negative refractive power; a fifth lens having positive refractive power; and a sixth lens having negative refractive power. The photographic lens satisfies the following condition: 90 FOV 160, 0.5 D1/D6 1.0, wherein the FOV is an angle of view in the photographic lens, D1 is an effective aperture of the first lens, and D2 is an effective aperture of the sixth lens.
