Even though each camera doesn’t offer full
functionality of the CLS features that each
Speedlight offers, there are some caveats, as
the next sections explain.
D50
With the D50, just because you can’t use the
built-in Speedlight as a remote commander
doesn’t mean you can’t use advanced wire-
less lighting. The SB-800 or the SU-800 can
be used as the commander for wireless
remote Speedlights.
D70/D70s
Although the D70/D70s does allow you to
use the built-in Speedlight as a commander,
it is somewhat limited. When used as a
commander, the built-in Speedlight does
not produce enough light to add to the
exposure (this can be good or bad). It
allows you to use as many remote
Speedlights as you need, but all of the
remote units can be used as only one
group. Therefore, any exposure compensa-
tions you want to make has an effect on all
of the Speedlights in the group.
Considering the price of the D70/D70s, this
is still an amazing and useful feature. Being
able to command even one off-camera
Speedlight without the purchase of any
additional accessories (other than camera
and flash) is a great deal.
