I also bought the D7 Mark II, but not at digitec. But I can't imagine that the package will be any different. The important thing to know about the adapter is that it comes in the form of an SD card, which means that this port is no longer available for storing images. It would still be possible to use the large CF card, but this is not really recommended.
So if you rely on WLAN, you're not really well served by this camera. But the pictures, especially in sports and other fast shots, are first class, love this camera!
