I just read an interesting article on Strobist about knowing your camera's sync speed. Apparently some manufactures fudge a little bit about cameras' true flash sync speeds. For instance, an EOS 5D MkII's advertised sync speed is 1/200 of a second, while many have found they must go down to 1/160 to get their whole frame properly exposed when using flash. A Sony a700, on the other hand, has an advertised sync speed of 1/250 or 1/200 with SSS turned on, while I've had little trouble lighting images with SSS turned on at 1/250.
Does anybody have any experience or input about the true
sync speeds of their Alpha cameras?http://strobist.blogspot.com/2010/01/know-your-sync.html
