Fringer Pentax P645-GFX auto focus adapter

I just received the adapter, have not tried it yet. The user manual (small as it is) recommends NOT allowing the camera to select the shutter speed. I am a seascape/landscape guy and usually shoot at f11 to f16. I mostly use Aperture Preferred Automatic on the camera. I set the F stop, select ISO, and allow the camera to select shutter speed. If the shutter speed is to low to hand hold or stop motion, I will boost the ISO until the shutter speed is to my liking. I will need to change my shooting regime while using the adapter. Anyone using a similar adapter here, this is what I guess I will do (the camera is a Fuji GFX 100S):
1. Set the Pentax lens ring to the Green "A" (This is a must do, it transfers aperture selection to the camera).
2. Set camera top dial to "M"
3. Use front Command Dial as a "Toggle". Push in once & rotate to change "F" Stop. Push in again & then rotate to change ISO.
4. Use Rear Command dial to Vary shutter speeds.

The two used Pentax lenses I purchased are the 300mm f5.6 AF, and the 400mm f5.6 AF. Being a very senior citizen, AF and IBIS are very important features to me. This adapter is reported to maintain AF, allow IBIS, and transmit EXIF data. I will report back with my experiences with this adapter.
PS: I have been a very long time Pentax medium format user, I had a Pentax 67, 645, 645AF, and 645D, so I am familiar with Pentax Optics.
Thanks for the input
