1. A new function added: AF adjustment (PDAF only)
In most cases, there should not be any accuracy issues when phase detection AF is engaged. But if certain individual lens has focus-shifting issues, an AF adjustment function is present.

1) Usage
i. Enable AF adjustment for the lens currently installed: Power on the camera. Enter function code “1212” using the aperture ring (see “3.8 Configuration fast switching” in the user’s manual). The camera will reboot automatically.
ii. Set AF adjustment value: Take the adapter off the camera. Connect it to a computer. Check “settings.ini” in the root folder. There should be a line newly added to the end of the file such as PdafFix001 = 0 ;Canon EF 40mm f/2.8 STM
iii. Change the “0” after the “=” to a value you want (between -30 and 30). Enter a positive value if the focus point needs to be moved towards infinity. Then save the file and disconnect the cable.
iv. Reinstall the adapter and the lens to the camera and do focus tests again. Repeat the above steps if necessary.

2) Additional notes
i. At most 10 lenses are allowed to use the AF adjustment at the same time. If the 11th lens needs to be added, you must edit the settings.ini and remove at least one PdafFixXXX line that is not needed anymore. ii. This AF adjustment function is valid for phase detection AF only. Thus,
it has no function on GF X50 series cameras.
ii. Only lenses tested and optimized support PDAF. Thus, the AF adjustment function is valid for tested and optimized lenses only. iv. In most cases, it is not recommended to use the AF adjustment function. Sometimes it can make things worse. Therefore, only if there is a big focus shift in a fixed direction and cannot be eliminated by multiple focusing, you can try this AF adjustment function.

2. Fixed AF performance issues for some lenses of the following models: Lens didn’t get recognized by the adapter due to different lens version.

1) Tokina AT-X M100 PRO D Macro 100mm f/2.8

3. Added following lenses to the tested and optimized lens list:
