主旨：A K-3 shutter delay with P-TTL flash bug report
Dear RICOH (PENTAX):
I'm a K-3 user _________,（有意回報的朋友可自行帶入姓名）
when I use the flash, internal or external,
there is a shutter delay between I press the button and the K-3 effectively take the photo.
The bug happened with P-LLT flash mode, but not with M flash mode.
Please report and fix the bug.
