A7iii with SEL70300G lens - focus problem

[AlansCamera]

Hi, the above combination of camera and lens will not autofocus on low contrast objects at infinity i.e. white clouds in a blue sky.  I have tried the lens on two A7iii cameras with the same problem.  My wife has the Sony A7iii with the SAL70300G lens using a lens mount adaptor and she does not have this problem.  Both cameras have been reset to factory settings and the SAL lens works perfectly on both whereas, the SEL doesn't.  Any suggestions will be appreciated.

Have you tried changing the Focus area or trying a different AF system such as Contrast or Phase detection? Making sure the camera has the latest software version to eliminate a possible software glitch for example.

Thank you John, changing the focus area seems to have done the trick.
