Figure 12-16. SB-R200 Speedlight
Then there are the SB-R200 Speedlight units (see
Figure 12-16). These are primarily designed to use in special
arrangements on brackets that Nikon created for them. You'll
see these Speedlights in use if you watch many crime dramas
on TV because the investigators often use them for close-up
flashes of crime scene evidence. They are normally used in a
group arrangement, including special mounting brackets, with
a Nikon SU-800 Wireless Speedlight Commander Unit. The
SU-800 is shown in Figure 12-17.
