I am in A modus. Diafragma is fixed to 4.0, time is 2.5" and ISO is 100. When I move my camera around these settings change depending on the ambient light. When I point to the window the shutterspeed changes to 1/200". This seems very logic.</P><P>When I press AF-ON (which is set to BackFocus) shutterspeed changes to 1/320" and only when I push to take my picture I see the ISO changing from auto to 400. Is this the normal way things happen?</P><P>So I have to focus before I can see if my shutterspeed is OK and my ISO is not too high?</P><P>Thank you for your reply</P> Sun, 04 Oct 2020 13:23:32 GMT https://community.sony.no/t5/alpha-nex-interchangeable-lens-cameras/sony-a7riv-about-diafragma-and-shutterspeed/m-p/3709389#M8911 todegro69 2020-10-04T13:23:32Z https://community.sony.no/t5/alpha-nex-interchangeable-lens-cameras/sony-a7riv-about-diafragma-and-shutterspeed/m-p/3710477#M8918 <P>According to the <A href="https://helpguide.sony.net/ilc/1930/v1/en/contents/TP0002711804.html" target="_blank">Help Guide</A> for the camera, in Aperature priority (dial mode A), this is how things are handled.</P> Wed, 07 Oct 2020 12:57:18 GMT https://community.sony.no/t5/alpha-nex-interchangeable-lens-cameras/sony-a7riv-about-diafragma-and-shutterspeed/m-p/3710477#M8918 Joe_Dohn 2020-10-07T12:57:18Z
