The shutter built into the Sinaron Digital CEF lenses is a traditional mechanical between-the-lens shutter of the

type that has been in use for professional photography for many years. For those who are not familiar with this

type of shutter, the comments that follow are intended to explain its proper operation:

2.10.1 Viewing the subject

The lens features two modes: The Viewing mode and the Exposure mode. In order to observe the subject

through the lens, the shutter has to be open. The shutter [31] can be opened or closed by means of the Shutter

setting knob [34].

2.10.2 Focusing

Focusing the lens on the subject is achieved by turning the Focusing ring [38]. The small f-stop numbers ar-

ranged symmetrically around the index line serve to indicate the depth of sharpness for the aperture that is be-

ing used. The numbers on the focusing ring itself serve to indicate the distance at which the lens is focused (in

meters and feet).
