[QUOTE="WayneF, post: 580554, member: 12496"] EC does not affect the camera Manual exposure. Because Manual exposure is whatever you have set it to be. EC will affect the light meter reading, which possibly you may or may not use to adjust exposure settings yourself, but the light meter reading is not automatically used by camera Manual mode. EC will not change Manual camera shutter or aperture settings. Manual is Manual. However, EC will affect Auto ISO, which will increase trying to make your Manual camera settings be correct, except presence of a hot shoe flash (not the internal flash) will limit the Auto ISO increase to only 4x your Minimum ISO setting (i.e., ISO 100 can increase to ISO 400). But EC cannot change Manual shutter or aperture settings. Manual flash mode - will be the flash level exposure you have set on it. Manual flash will not be automatic, EC will have no effect on it. And Auto ISO cannot increase at all with a manual flash (Manual flash cannot respond to ISO changes). TTL flash mode - IF EC is also affecting TTL flash (E4) , it will affect metered TTL flash exposure. TTL flash will try to be correct for EC and for ISO (within the 4x ISO limit). And flash of course will contribute to the overall scene exposure. [/QUOTE]
