  That's not a limitation of the camera - I think it's a limitation of 
the manual. :)

  What they're really trying to say is that large studio flash units 
tend to produce longer-duration pulses of light than small portable 
units. So it may be necessary to limit your shutter speed to 1/125 to 
avoid flash sync problems.

  However, the camera has no way of knowing if it's plugged into a 
studio flash unit or a little battery-powered flash unit when you're 
using a PC cord or an optical slave. It shouldn't behave any 
differently either way.
