To use the autofocus mode, slide the focus mode switch until it is aligned with the AF mark (4).

For manual focusing, slide the switch to the MF(M) mark, and rotate the manual focusing ring.

•

Do not touch any moving parts on the lens during autofocusing.

Two autofocus ranges are selectable with the lens (5).

0.6- ∞ : From closest focusing distance to infinity.

•

1 - ∞:From 1 m to infinity. For normal use. Focusing time will be shorter when

•

set in this range.

When the subject is in focus, there is a certain area in front of it and behind it which

will also be in focus. This range of sharpness is called depth of field. It can be

checked on the lens depth-of-field scale. To check, find the two aperture numbers

on the depth-of-field scale on the lens, then draw imaginary lines from these two

numbers to the distance scale, The effective depth of field lies between these two

distances. For example, using a standard 50 mm lens focused at 2.5 m (8 ft) with

the aperture set at f/11, depth of field extends from approx. 1.8 m (6 ft) to 4 m (13

ft) Any subject in this range will be in reasonably sharp focus.

With black and white infrared film, it is necessary to make a slight

adjustment in focus XVLQJ LQIUDUHG LQGLFHV After focusirig as usual, make this

adjustment by turning the manual focusing ring to align the focused distance with

the infrared index (7). When shooting, be sure to use a red filter.

•

Switch the focus mode to M to tum the manual focusing ring for adjustment.

•

The position of the infrared indices is based on film usage with a peak sensitivity of 800 nm and a red filter (such as

Wratten 87). Using black and white infrared film with a different sensitivity may require a slightly different setting. Thus,

it is recommended to take trial shots with the focusing ring set slightly to the left and then right of the appropriate index

to find the best position.

•

Please carefully read the infrared film manufacturer's instructions and the camera's instruction manual for further

details.
