There is a bug in the 1.12 firmware for the K-5. AE-L does not lock settings on the camera in Av mode.

The issue is easy to reproduce:

  • Mount a DA prime on the K-5

  • Set the K-5 to manual focus

  • Set the camera to Av mode

  • Set the AE-L lock and confirm the * in the viewfinder

  • Simply rack focus to infinity and back and note the change in ISO value in the viewfinder.

Tried these with the DA* 300/4 and the DA 16-45/4. My K5 with firmware 1.12 behaves with both lenses like expected, and doesn't change ISO.
