The Lemo2 connector, as well as Lemo6, Lemo8 and Amph9

accessory connectors, provide the capability of using a remote on/off

with either a half-frame or full-frame inching function.

2.9 LIGHTMETER

The XTRprod is equipped with an internal lightmeter that is

designed to read the quantity of light reﬂected off the ﬁlm itself. For

added accuracy, the meter measures the light by means of two

photocells. The metering system automatically compensates for

ﬁlters and changes in camera speed.

2.9.1 Display

Through the viewﬁnder, the lightmeter display is positioned directly

below the viewing screen across the bottom of the frame. A single

darkened diode moves across an array of 13 yellow and green diodes,

indicating proper exposure (see diagrams). Each diode represents

one third of a stop, while normal exposure darkens the center green

diode. Underexposure of -2 stops or more darkens the green diode

on the left end of the row; overexposure of +2 stops or more darkens

the green diode on the furthest right of the display.

To the immediate left of the display is the red diode indicator,

which has the same functions as the red diodes on the left and right

sides of the body. See section LED Indicators for further details.

2.9.2 Operation

Because the lightmeter takes its measurement as a reﬂection off the

ﬁlm, you must have ﬁlm in the gate for the camera to provide an

accurate reading.

To use the lightmeter, follow these simple guidelines: Set the ISO

selection on the control panel to the exposure index of the ﬁlm
