6. Depth-of-Field Scale

(TS-E24mm f/3.5L)

The depth of field is the distance in front of and

behind the plane of focus on the subject that

appears sharp. The depth of field is indicated by

the area between the depth-of-field scale lines

below the distance scale. Numbers in the scale

are in F values, and for example, if the shooting

distance is 1.5m and the aperture is f/8, the

sharp area will extend from about 1m to 3m.

●

The depth-of-field scale is only valid when the

tilt scale is set to the "0" position.

●

The depth-of-field scale is an approximate

indicator.

7. Infrared Index

(TS-E24mm f/3.5L)

The infrared index corrects the focus setting

when using monochrome infrared film. Focus on

the subject, then adjust the distance setting by

moving the focusing ring to the corresponding

infrared index mark.

Some EOS cameras cannot use infrared film. See

the instructions for your EOS camera.
