Instruction manual

* The aperture ring must not be adjusted while the depth of field pre-

view is being depressed.

* If exposure measurements are taken with the depth of field preview

lever depressed, when using a finder with built-in exposure meter, the

shutter speed setting indicated will cause over-exposure. This is

because proper exposures are obtained with exposure measure-

ments made at the full aperture.

A. The lens is focused on the subject, by rotating the focusing ring in

either direction, while checking the effect on the micro-prism / split-

image range finder spot in the center of the focusing screen (stan-

dard type).

B. The central split-image spot splits the image into two, with the

upper and lower halves separated horizontally when the lens is out of

focus. When in focus, however, the two halves will coincide with the

displacement disappearing.The micro-prism ring surrounding the

central spot can also be used for checking the sharpness of the

focused image, since the image will glitter when the lens is not

focused. The surrounding full-area matte surface can also be used for

checking overall image sharpness.

A. Distance scales on the Zenzanon PS lenses can be used for focus-

ing at the required distance or finding the distance actually focused.

Simply rotate the focusing ring and set the required distance oppo-

site the orange-colored index, which will adjust the lens for the

required distance.
