This is widely used in specs -- look here on dpreview: dpreview.com/reviews/Canoneos600d/page2.asp where the specs on the Canon 600D are listed. Anyhow, let's stay with the topic the OP raised, which is ratios. | |

| Oct 25, 2011 at 22:01 | comment | added | Steve Ross | I didn't mean to imply that sync speed depended on the flash, but it is irrelevant without one. That's why it is so often called "flash sync speed". The whole point of this is that there is a maximum shutter speed your camera/lens setup can achieve and still guarantee the flash will have discharged while the shutter is completely open. This is the maximum flash sync speed. Because it is about the speed with which the camera can sync with the flash. | |
