The light metering system of the HVD90X is capable of selec-
tive sensitivity producing three reective metering methods:
Average, CentreSpot and Spot. All methods are measured in
increments of 1/12 EV. Information transfer is rapid and auto-
matic ensuring consistently correct exposure settings even in
dicult and changeable lighting situations.
Light measurement is made through the lens (TTL) and ex-
posure is controlled manually or automatically by the control
wheels and/or settings. The information is visible on both the
grip display and the viewnder display.
A great deal of control is available ranging from 100% manual
through to sophisticated fully automatic by way of the various
exposure methods: Manual, Aperture priority, Shutter prior-
ity, Program and Program variable.
