Originally posted by old4570 I know some other cameras have an option in the menu to increase the sync speed at which the camera will fire the flash , does the K5 offer this ? ( I havent found any such option )
What most cameras will do is allow the flash to be fired even though the physical sync speed limit has been exceeded.
This can result in the shutter to obscure a portion of the sensor and not allow the flash to fully expose the image.
When used with strobes that have long flash durations and/or with triggers that handle this special case, the effect can be minimized even with exceptionally high shutter speeds.
Sadly, Pentax completely disables the ability to fire the flash via the standard hot-shoe and PC pins when the sync speed is exceeded.
So unless you have a PTTL compatible flash with HighSpeedSync capability, you are simply SOL and limited to the camera's sync speed.
