And why is it that there is a reduction between the 1/250 natural sync speed and 1/320 non-HSS speed? (I've since learned that the power loss is a little less than 1 stop, still better than the more than 2 stop loss from switching to HSS.)<br /><br />Best regards,<br />Mic360 Rumorshttps://www.blogger.com/profile/01173469932778454315noreply@blogger.comtag:blogger.com,1999:blog-2361251099864607419.post-13592712052672342632013-11-13T20:04:06.795-08:002013-11-13T20:04:06.795-08:00Trying to contribute to your blog again.

When you think about it, the fast shutter speed that you can obtain without the two curtains traveling together (i.e., x-speed) is the time it takes for the first curtain to clear the sensor. The x-sync speed cannot exceed that speed. For a faster shutter speed, the second curtain must start traveling before the first curtain completely clears the sensor. With a better, improved mechanical shutter, the curtains will travel faster and result in higher x-sync speed.Anonymousnoreply@blogger.com
