I thought the Riv was able to switch eye's when eye AF selects the wrong eye. I sure wish they would make it always select the eye closest to the camera but sometimes it does not and if I'm shooting 135 1.8 the second eye is already getting soft if they are at an angle to my lens. I can find no way to switch eyes and that was the feature I was most excited for upgrading from my A7iii.

On auto it should normally focus on the closest eye but will get it wrong occasionally. You can assign the Switch Right/Left Eye function to a custom button though which should help when this happens.

Here's the relevant bit from the online help guide:

====================

[Switch Right/Left Eye] by custom key

When [Right/Left Eye Select] is set to [Right Eye] or [Left Eye], you can switch the eye to be detected by pressing the custom key to which you have assigned the [Switch Right/Left Eye] function.

When [Right/Left Eye Select] is set to [Auto], you can temporarily switch the eye to be detected by pressing the custom key to which you have assigned the [Switch Right/Left Eye] function.

The temporary left/right selection...

The temporary left/right selection is cancelled when you perform the following operations, etc. The camera returns to automatic eye detection.

  • Pressing the center of the control wheel
  • Pressing the center of the multi-selector
  • Stopping pressing the shutter button halfway down (only during still image shooting)
  • Stopping pressing the custom key to which [AF On] or [Eye AF] is assigned (only during still image shooting)
  • Pressing the MENU button

Is it litterally called right/left eye in the custom menu? If so I must have been going too fast and skipped right over it.

It's called Switch Right / Left Eye to be exact. It's under AF3 (6/27).
 
Well I sure would have known what that was if I saw it LOL. Still not sure how I missed it. Thank you!
