I was over at Tim's RF Shooters Forum earlier and was reminded that I need to tell the camera about the focal length of any manual lens that I have attached....
From The Google AI:
"To configure the Sony Alpha 1 Mark II (A1 II) to recognize the focal length of a fully manual lens (one without electronic contact pins), you must manually enter the value into the camera's image stabilization settings. This ensures the In-Body Image Stabilization (IBIS) system moves the sensor accurately to prevent blurry shots. Because manual lenses cannot communicate data automatically, following this specific menu path will map the correct focal length:
Step-by-Step Configuration
1. Press the MENU button on the back of the camera.
2. Navigate to the Shooting menu (the red camera icon).
3. Scroll to the Image Stabilization sub-menu.
4. Select SteadyShot and ensure it is toggled to On.
5. Select SteadyShot Adjust and switch it from Auto to Manual.
6. Go down to Focal Length (or SteadyS. Focal Len.).
7. Select the exact focal length matching your physical lens (options range from 8mm up to 1000mm).

Tips for Manual Lens Shooters
- Map a Custom Key for Quick Changes: If you regularly swap between different vintage or fully manual prime lenses, navigating the menu every time is tedious. You can go to MENU ➔ Setup (Yellow Toolbox) ➔ Operation Customize ➔ Custom Key/Dial Set. and assign the Focal Length setting to an easily accessible button (like the C3 button or Function (Fn) menu). This lets you twist a dial to change focal lengths instantly when switching lenses.
- Enable Release W/O Lens: Because manual lenses don't have electronic chips, the camera might think a lens isn't attached. Make sure to navigate to your setup settings and verify that Release w/o Lens is enabled so the shutter will actually trip.
