The inside telephoto lens near the feeling which looks at people with the naked eye. The technology of high refractive-index glass, a ghostless coat, etc. is poured out unstintingly, and depiction power which was effective to 0.7 m of the shortest object distance, and power of expression of rich gradation copied and crowded to the delicate shade are realized. The brightness of F1.8 and the natural dotage taste by a nine-sheet iris diaphragm shuttlecock bring depth to a work. compact -- aluminum shaving appearance is carried out and the finger point of cloisonne ware shines on a body. performing the design not only based on the numerical evaluation by choice depiction characteristic various testing machines but advanced on-the-spot photo evaluation -- softness moderate in "iris diaphragm opening -- while narrowing down -- the 鮮鋭な像 performance ", a feeling of "air and gradation, and gradation -- depiction of the - cubic effect "is enabled. The FREE system to which only a pre-group is moved with the back group of a lens system fixed is adopted as focusing focus 合わせ by a FREE system. The image performance stable from the short distance to the long distance is obtained. Use and finish as for which a high-class feeling and a precision feeling exist are given to the main part of a design lens as for which a high-class feeling and a precision feeling exist for the aluminum material. Moreover, in adoption and a material, it is a dark green color about the "finger point" which improves the wearing nature to a camera body. Cloisonne ware was used. * The focal length at the time of equipping *istD is 118 mm (35-mm seal conversion) in focal length. / [degree] of field angle 21 composition number-of-sheets [group * 枚] 6, and the 7 minimum iris diaphragm [F] 22 -- 64xdiameter of the diameter [mm] of shortest object distance [m] 0.7 filter49 maximum x length [mm]48 mass [(weight) g] 270
