[QUOTE="WayneF, post: 375220, member: 12496"] Camera A mode and P mode simply default to 1/60 second if the flash is recognized present (PC sync cord or radio trigger flash are not recognized present, so this does not happen). This is a minimum shutter speed with flash. Ambient in a less bright room might meter less, say 1/8 second. If you turn on the flash, then the system thinks you don't need 1/8 second (you are using flash instead), and it jumps to 1/60 (A and P modes). That is NOT a metered value (which was the 1/8 second). It is just a minimum when using flash (A or P mode). Camera S or M modes use the shutter speed you set. There are exceptions. The higher end models (lets say those with Commander) have a menu E2 to set the Minimum Shutter Speed With Flash. You can set it slower, but cannot set the Minimum faster than 1/60. If you need it faster, either use camera M mode, or go out into brighter light. Or, you can specify either Slow Sync or Rear Curtain Sync, and both of these ignore the Minimum, and use the slow shutter speed that was actually metered. Or, if in bright light that already meters more than 1/60, it will use what it meters. So this Minimum is not often a factor outdoors in daylight. [/QUOTE]
