The Panasonic adapter allows all your information to be saved on the EXIF, but will not allow AF unless you are using one of the Firmware updated (for contrast AF) 4/3 lenses. It will also allow for zoom MF if you want, where moving the focus ring on your 4/3 lens can automatically be set to zoom in and allow critical focus (like for macro work). The Jinfinance adapter works like any other non-electrical mount, you just use MF and the zoom function is a couple of button clicks.
