17. According to users’ feedback regarding the complexity of editing SETTINGS.INI on the adapter which requires a computer, we added configuration fast switching function. When the camera with the adapter and the lens is powered on and in shooting mode, user may use the aperture ring to enter a 4 digits function code to change a configuration item.

Detailed steps are as following (Take entering function code “1234” as an example. “Forward” and “backward” are relative. You may decide which direction is forward by yourself).

1. Half-press the shutter button once and finish step 2) - 6) in 20 seconds.
2. Turn aperture ring 1 step forward. It’s the first digit.
3. Turn aperture ring 2 steps backward. It’s the second digit.
4. Turn aperture ring 3​ steps forward. It’s the third digit.
5. Turn aperture ring 4 steps backward. It’s the fourth digit.
6. Half-press the shutter button.
7. Now, the camera will reboot automatically. After that, the configuration has changed.

Note: During aperture ring operation, please ignore the response of the camera and the lens. Just pay attention to the feel of steps and the click sounds of the aperture ring.

6. Added a fast switching function code (“1234”) for “FocusBracketing=” in SETTINGS.INI. Check section 5 above for the detailed operation steps. User

may switch it between 1 (enable focus bracketing support) and 0 (disable focus bracketing support). Actually, it sets camera in native lens mode (1) or adapter mode (0). See section 7 bellow for more descriptions.

7. Added in-body vignetting and distortion correction profile for some fast primes. So far, the lenses supported are listed in the following table (table 1):

Lens model Configuration item default Canon EF 35mm f/1.4L II USM ForceNativeEF3514L = 1 Canon EF 40mm f/2.8 STM ForceNativeEF4028STM = 1 Canon EF 50mm f/1.8 STM ForceNativeEF5018STM = 1 Canon EF 85mm f/1.2L II USM ForceNativeEF8512L2 = 1 Canon EF 85mm f/1.4 L IS USM ForceNativeEF8514LIS = 1 Canon EF 100mm f/2.8L IS USM ForceNativeEF10028LIS = 1 SIGMA 40mm F1.4 DG H​SM A018 ForceNativeSigma4014A = 1 SIGMA 50mm F1.4 DG HSM A014 ForceNativeSigma5014A = 1 SIGMA 70mm F2.8 DG MACRO A018 ForceNativeSigma7028A = 1 SIGMA 85mm F1.4 DG HSM A016 ForceNativeSigma8514A = 1 SIGMA 105mm F1.4 DG HSM A018 ForceNativeSigma10514A = 1 TAMRON SP 35mm F/1.8 Di VC USD F012 ForceNativeTamron3518VC = 1 TAMRON SP 45mm F/1.8 Di VC USD F013 ForceNativeTamron4518VC = 1 TAMRON SP 85mm F/1.8 Di VC USD F016 ForceNativeTamron8518VC = 1

There are two working modes of the GFX cameras, i.e., adapter mode and native lens mode, as described in the following table (table 2): Function of adapted lenses Adapter mode Native lens mode Focus bracketing Not supported Supported IBIS Fully supported Degraded or not supported for some lenses Vignetting and distortion correction profile Not supported Supported Mount adapter setting menu Available Grayed out 35mm format mode “AUTO” Crop to 35mm Keep 44 x 33 frame By default, “FocusBracketing=” in SETTINGS.INI on the adapter decides whether set camera in native lens mode (the value is 1) or adapter mode (the value is 0) for all lenses.

The newly added Vignetting and distortion correction profile function will be activated only if the camera is set in native lens mode.

For each lens in table 1, we added a configuration item named ForceNativeXXXX to the SETTINGS.INI.

The default value is 1 which means setting the camera in native lens mode to activate the profile embedded in the adapter regardless of the global setting, i.e., “FocusBracketing=” is 1 or 0.

In other words, these two settings are logically OR.

Since the IBIS performance of some adapted lenses may be degraded or disabled when the camera is in native lens mode, usually we don’t suggest to set camera in that mode.

But the lenses in table 1 are exception.

We are sure they won’t be affected by that issue and IBIS works normally in native lens mode.

But if you still

10

want to use then in adapter mode, you may modify the value of corresponding ForceNativeXXXX item to 0. To understand which mode your camera is currently in, there are two simple ways.

1. You may set “35mm format mode” to “AUTO” in camera menu. If there is a “35” on the top left of the screen, it’s in adapter mode.
2. You may check the “Mount adapter setting” menu item. If it’s grayed out, it’s in native lens mode.
3. If the lens on the adapter is in table 1, the corresponding configuration item ForceNativeXXXX’s value can be changed easily between 1 and 0 by the aperture ring. The function code is “4321”. Please check section 5 for detailed steps.
4. Fixed possible lens IS and IBIS conflicts in native lens mode.
