When using a lens directly mounted on the camera：

  • When the autofocus mode is set to something other than AF-C and the amount of focus movement is large until the focus is achieved, sometimes the exposure is incorrect after focus is achieved. You can use this with system software Version 1.20 or higher installed in the camera.
  • Exif lens names will not be recorded correctly. Update the system software of the camera to Ver. 3.10 or later to ensure correct display.

When using a teleconverter lens：

SEL14TC

  • The camera may be out of focus when set to Continuous AF.
  • The focal length and maximum aperture for the Exif lens name will be listed using magnification values. However, when the aperture values multiplied by magnification are 10 or higher, they will not display correctly. If you update the camera system software to Version 3.10 or higher, the name of the lens itself will be listed along with the name of the Teleconverter.
