Below
is a chart that shows the ISO ranges for all the Custom b2
settings:
1/3
EV Step ISO Range (b2 Factory default)
100, 125, 160, 200, 250, 320, 400, 500, 640, 800, HI-1, HI-2
1/2
EV Step ISO Range
100, 140, 200, 280, 400, 560, 800, HI-1, HI-2
1
EV Step ISO Range
100, 200, 400, 800, HI-1, HI-2
As
seen above the ISO sensitivity can be set between values equivalent
to 100-800 ISO in 1/3, 1/2, or 1 EV steps. HI-1 is roughly
equivalent to 1600 ISO, and HI-2 to 3200 ISO. The “HI”
steps are always simply 1 step apart, with no in-between settings
like with the 100-800 ISO range.
I leave my D2x set to the 1/3 step default,
because I like to be able to use small increments when needed.
Some may prefer larger EV increments, and they are there if
desired.
Now, let’s look at the two ways to set
the ISO number in your D2x. It can be done from within the
menus, or by simply holding down the ISO button and turning
the main command-dial on the back of the D2x.
ISO
Selection Method One: Notice that, in Figure
5, there are two Shooting Menu screens used to select an ISO
number:
Find
the Shooting Menu, scroll down to ISO, and toggle right to
the ISO selection screen. You'll notice that the ISO selection
screen displays all ISO values in 1/3 EV step increments.
Simply select your desired ISO and toggle to the right.
ISO
Selection Method Two: The second method of
selecting ISO is by far the easiest and fastest method.
Using
Figure 6 as a guide, hold in the ISO button while rotating
the Main Command-Dial. The ISO Sensitivity Readout on the
small LCD will change as you rotate the dial. This is a very
fast and easy way to change the ISO value, and most will use
this method.
If
you have previously set Custom Setting d5 to “Exposures
Remaining” your ISO Sensitivity Readout number (Figure
6) will only show up when you have the ISO button pressed.
(see page 196 in the D2x manual). The factory default is for
the ISO number to show in the small rear LCD, so, if you can
see it, Custom Setting d5 has not been changed.
