2 Days ago I bought an EOS 300D for £50 from eBay with 18-55mm lens! (bargain), but I've noticed that when I use the internal flash I'm restricted to 1/200sec shutter speed rather than the full 1/4000thsec which I can do without the flash, I presume this is due to the flash being incapable of working fast enough (correct me if I am wrong). Does that mean if I get an external high-speed flash/speedlight (meaning one capable of such speed) will I be able to use the high shutter speed with a flash?

Others have covered the whys & wherefores of needing HSS at faster shutter speeds but I'm going to ask why do you think you need a faster shutter speed?  Flash duration is typically around 1/1000th (flash power/duration is another subject), so at sync speed indoor typically the flash is providing all the illumination and it doesn't matter that much whether you are using 1/100th or 1/200th shutter speed, or 1/1000th shutter speed.

However if you were outdoor where with no flash you needed a shutter speed of more than 1/200th then wanted flash as well to illuminate shadows you'd need HSS.  The power of an external flash will drop off massively as it is basically a series of low power pulses.

So again it is worth asking - why do you (think you) need the higher speed?  What are you photographing?
