It says "X sync closes the flash contact just as the shutter blades are almost open (..)"
This sounds like it describes the point in time just before the shutter opens, i.e. even before light is let through the lens. It should read something like "X sync closes the flash contact just as the shutter blades are completely open (..)" -- Schorschi ( talk) 08:41, 19 August 2009 (UTC)
"but some modern cameras may have an X-sync speed as high as 1/500 (e.g. Nikon D70)." The Nikon D70 and the D40 have an electronic shutter in addition to their focal plane shutter, so this is inaccurate.
True, the hybrid shutter of the D70 (and perhaps also the D40, I have never used one so I cannot verify this) makes it possible to synchronize at all shutter speeds if you just trick the camera into believing that there is no flash attached. A piece of non-conductive tape over the two contact closest to the back of the hot-shoe will do the job. Of course, the flash will have to be in manual mode since no communication between the camera house and the flash unit is longer possible. Maxzom ( talk) 12:22, 21 February 2010 (UTC)
"Leaf shutters, (...) , can move much faster than focal plane shutters and allow flash sync across all shutter speeds (..)." While it might be true that leaf shutters can move faster, this is not the correct reason. The reason why leaf shutters can sync across all shutter speeds are that there IS one moment during exposure where the shutter is fully open and thus exposes the whole film frame/sensor. As opposed to the focal plane shutter where the curtains at one point start to expose only a (moving) strip of the film frame/sensor. Maxzom ( talk) 12:27, 21 February 2010 (UTC)
Hello all from russian Wiki! Please, explain to me a few questions.

Can anybody provide an example photo that doesn't use photography equipment as its subject? I wasted a few seconds staring at the old Pentax camera before realizing that it is irrelevant to be point being conveyed, and that this photo is actually on this article because of the overexposed top half and underexposed bottom half.

"Only certain camera and flash combinations support this feature, and the camera-flash pairings are almost exclusively from the same manufacturer. Wireless remote flash triggers with these features are becoming more common." This is no longer at all true, now the vast majority of flashes sold are third-party wireless flashes that support HSS. 71.63.160.210 ( talk) 19:54, 25 December 2021 (UTC)
