I use the A7RV body. I think all settings are correct! It’s been updated too. Any tips or ideas how to get it tested in case it’s not a user error?&nbsp;</P> Sat, 16 Aug 2025 07:24:20 GMT https://community.sony.rs/t5/alpha-nex-interchangeable-lens-cameras/please-help-sony-200-600-g-oss-out-of-focus/m-p/3981342#M11966 Viki_Rose 2025-08-16T07:24:20Z https://community.sony.rs/t5/alpha-nex-interchangeable-lens-cameras/please-help-sony-200-600-g-oss-out-of-focus/m-p/3981343#M11967 <P>The old classic method is to point to a detailed wall with the camera on a tripod.</P><P>Be sure of the focus.
