2.2.4 Adjusting the Diopter

Before shooting, the diopter setting of the viewﬁnder should be

adjusted to the operator’s eye. To set the diopter, locate the diopter

set ring (d) in front of the carrying handle at the top of the

viewﬁnder, and loosen the small knurled knob. Look through the

viewﬁnder, rotate the diopter set ring until the edge of the cross-hair

is at its sharpest point and retighten the knob. It is recommended

that, for easiest setting, this adjustment be performed with the port

cover off and no lens on the camera.

Notice that the diopter set ring is engraved with numbers and dots -

use this reference to quickly recall your particular setting when more

than one person will be looking through the view-ﬁnder.

The range of the diopter setting is + or - 3. If the range does not

reach your particular diopter setting, the viewﬁnder optics can

quickly be adjusted by a qualiﬁed technician and the diopter range

reset to meet your needs.
