When you are performing flash photography using a flash mounted
on the Hot Shoe, if the Top Status LCD displays a value of 200, the
actual shutter speed is 1/180 sec.
E-TTL Autoflash
With E-TTL (Evaluative Through the Lens) Autoflash, the correct flash
exposure is determined by the DCS Pro SLR/c. The E-TTL Autoflash works in
any Auto Exposure mode. However, you may want to use a tripod to avoid
camera shake for situations where a slow sync speed has been set. The
standard shutter speed range for all flash units is 30 sec. to 1/180 sec.
