[QUOTE="voxmagna, post: 494845, member: 38477"] I started using the Auto ASA features in Aperture priority mode only to find the D750 setting itself to ridiculously high ASA values. I then set the maximum ASA to 3200 and minimum to 200 ASA with a minimum shutter speed of 1/30. The zoom lens I'm using has image stab. and hand held shots at 1/30 are in focus. In daylight the ASA sits at 200 as I expect and in low light the ASA moves up to the limit with the Auto ASA flashing. That seems to work as I would expect. Then I popped up the internal flash to find the ASA was still set to 3200. I turned off Auto ASA and set it manually to 200. The short range indoor shot with popup flash was repeated and perfectly exposed without noise. Can anybody explain what is going on? It is almost as if Auto ASA is being set first for a shot without flash to its highest value, then the flash power is adjusted downwards rather than ASA first. I checked the EXIF data and the flash shot was taken at ASA 3200. Do you all use the Auto ASA feature as I'm thinking it may be best to adjust manually in future. [/QUOTE]
