I already have my K-X so I might as well use it. Also, are there any disadvantages to HSS? I thought it was good for a more natural light and keeping the background intact?
HSS sync is the ability to sync the flash over your x-sync speed.
for example if your camera x-sync is at 1/200, if you are at 1/250 you'll get a partial black curtain (just try it and you'll know).
HSS allow some camera to go to 1/8000 and still get regular images.
But as with all flash it's all about that double exposure, one with ambient light and one with the flash.
for example doing f/2.8 ISO 100 1/8000, most likely you are gonna get a completely black out image without the flash in most condition. Now you hit that with a flash, and whatever the light hit, you get your exposure, so in most cases your flash power hitting an area of 2 feet radius, that area will show up, the rest is black.
so HSS has it's use, just need to use it the right way.
