High Speed Sync

I always thought the built-in flash of my Nikon cameras can do high speed sync on its own.  Wrong!
How often do I flash?  Not too often.  And when I flash I either flash using the SB-800 or my Sunpak 120-J.  And honestly I seldom use high speed sync and when I do it's with an external Nikon flash like the SB-800 or my broken SB-600 if I ever did.  But I always thought it can be used with the internal pop-up flash.

Well today I tried because I was too lazy and too weak to carry an external flash and a battery pack let alone any trigger or light stand.  It's not worth it.

So I thought that little flash can sync above 1/320.  Wrong.  The fastest it goes is 1/320.  So the pictures can't be too crispy.  But then again it's not at all that bad if you manage to catch the right moment and don't look at it at 100%.

Right now I almost think it's imperative to shoot with a flash otherwise the pictures look kind of flat and lifeless.  But that's just one man's opinion.
