Figure 12-15. SB-600 Speedlight
The Nikon SB-600 Speedlight unit is the low-cost flash for
users on a budget. It is only about one stop less powerful than
the SB-900 or SB-800 unit and costs considerably less (see
Figure 12-15). Buying several of these won't set you back
much and will allow you to set up a great CLS system with
your D300(S). If you are just getting started in CLS, these
might be your best investment. The SB-600 does not have a
built-in Commander mode itself, like the SB-800 and SB-900,
but you don't need it since your D300(S) does.
