No, the camera fires a preflash and reads that via the main metering cell after stopping down the lens but before flipping up the mirror and uses that to determine power settings for the final flash. There is no exposure control of the flash during exposure with P-TTL on digital (there may be with film P-TTL, I'm not sure). -Adam -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
