Viewfinder Exposure Confirmation In addition to the auto check lamp on the flash unit, the LX, 645, and other "programmed" Pentax models (refer to pages 10 and 11) also provide auto flash confirmation inside the viewfinder, following your flash exposures. If the subject received sufficient light, the LED or LCD flash ready indicator inside the viewfinder will flicker. Flash Override With the Pentax LX featuring IDM system, when the flash is set in TTL Auto or Two-level Auto flash mode, the camera's auto exposure system will override the flash when the shutter speed exceeds the required flash speed (see "TTL AUTO OPERATION," page 16).
