But did you test it out under daylight? Because the test is meaningless if done indoors. When in the dark with flash ready, the shutter speed and aperture selected by the camera does *not* depend on ambient light in program modes. They were preset based on focal length and programmed modes; that's why adjusting the exposure compensation did not seem to change anything. In this circumstances, the exposure compensation dial does exactly what it is supposed to do - adjusting the flash output as it is the dominant light source. You have to do the test in daylight, where flash exposure compensation is most useful and where you want to adjust the fill flash ratio. I find it hard to understand how it could work if what you found was true - as one may really need exposure compensation adjustment of ambient light exposure. You do need two separate adjustment for ambient and flash exposure to achieve desired fill flash control, as you would in MZ-S/ZX-L with AF360FGZ. > This is great--I have control of my fill flash ratios with any > flash on the camera, even the pop-up! I am afraid not, judging from the confirmation email you got from Pentax. Daylight fill flash situation is quite different. Anyways, test it out under daylight and see what you find. > I just don't understand why they would leave this out of there manuals. Because that's how exposure compensation is expected to work under programed TTL flash. Shutter speed and apertures are selected based on focal length of the lens and the programmed mode, and flash output is controlled to give proper exposure (which depends on film speed, exposure compensation, TTL sensor exposure reading). If it behaves exactly the same in daylight and fill flash situation, I would be very surprised, as this would be totally unexpected in how exposure compensation adjustment is supposed to work. -- --Lawrence Kwan--SMS Info Service/Ringtone Convertor--PGP:finger/www-- [EMAIL PROTECTED] http://www.vex.net/~lawrence/ -Key ID:0x6D23F3C4--
