85mm tl2.Sstandard


 The standard lens'is KOWA B5mm f/2.8, composed
 of 5 elements in 4 groups Xenotar type, equipped
 with  between-thelens leaf-shutter SEIKO SLV
 #O. Tak ing angle of  standard lens  is SO"20' ,
 which is equivalent to that of 46mm lens in 35mrr,
camera.
 In a single lens reflex camera it  is necessarythat
 the standard lens has a relatively tong flange back
compared with  its focal length, and it is becauseof
 this requirement lens correction is difficult. The
standard lens KOWA B5mm f /2.8 is corrected with
such nicety that despite having sufficient flange
back, it leavesminimum spherical,astigmaticand
distortional  aberration. Also, there  is the  least
image curvature and coma flare.  lt  gives an ex-
ceptionally sharp and high contrast image even at
full aperture from the center to the marginal edge.





The diaphragm consist of 5 leavesand is pentagon
in shape. These leaves are colored black under
specialtreatment which prevents internal reflection.
The lens is given selectedcoating of magenta and
amber according to curvature and material, as a
result f lare is reduced and color rendition is superb.
Minimum  focusing distance is 0.8m, minimum
aperture is f 122 and aperture scale is equipped with
click-stops at each half f/stop.
