INNER FOCUS TYPE LARGE-DIAMETER TELEPHOTOGRAPHIC MACRO LENS WITH VIBRATION-PROOF FUNCTION

摘要

PROBLEM TO BE SOLVED: To provide an inner focus type large-diameter telephotographic macro lens with vibration-proof function capable of acquiring a favorable optical performance while suppressing enlargement of the product external diameter.;SOLUTION: The inner focus type large-diameter telephotographic macro lens having the vibration-proof function includes, in order from an object side to an image surface side: a first lens group L1 having positive refractive power; a second lens group L2 having negative refractive power; a third lens group L3 having positive refractive power; a fourth lens group L4 having positive refractive power; a fifth lens group L5 having negative refractive power; and a sixth lens group L6 having positive refractive power. The telephotographic macro lens is configured to substantially perpendicularly move the fifth lens group L5 to an optical axis so as to move the image.;COPYRIGHT: (C)2013,JPO&INPIT
