Check to see if you moved the Shutter release button to Quite instead of Single. That is the ring where you set it to multiple frame of mirror up. Quiet Shutter Release mode works just like Single Frame mode but makes less noise as it goes about its business. Designed for situations when you want the camera to be as silent as possible, this mode automatically disables the beep that the autofocus system normally sounds when it achieves focus.[FONT=arial, verdana, sans-serif] [/FONT]But if I remember correctly it causes the mirror to stay up till you release the shutter button.
