80DX, SB-600, and SB-800 being the only flashes that can be
used for D-TTL. Other (mostly older) flash units, including the
original SB-28,
cannot be used in TTL flash modes with these
Nikon DSLRs
. Indeed, if you attempt to do so, the shutter
release locks and you can’t take pictures until you set the
Speedlight to Automatic (A) or Manual (M) flash modes.
With the D2h introduction, Nikon updated the flash system a
second time to something Nikon calls i-TTL (they also call the
entire set of new flash capabilities CLS, for Creative Lighting
System). The D40, D40x, D50, D70, D70s, D80, D2hs, D2x,
D3, D200, and D300 all use this i-TTL capability.
Unfortunately, a side effect of the i-TTL update is that
only
the
SB-400, SB-600, SB-800, SB-R200, and internal flashes
support it. This is a critical change to note. Just to be clear:
To get TTL flash on a D300 you must
use the internal flash, an SB-400, SB-600,
an SB-800, or an SB-R200.
Let me summarize a few things that are different between the
three basic Nikon flash technologies before we go on. I
realize that some of the terminology may be new to you, but
by the end of the section on flash you should be fully up to
speed; just come back to this chart then.
