You can attach anything to the hotshoe or bottom tripod mount.
pic rel: fujifilm x-s20 with fuji 18-55mm f/2.8-4, leather case, some proprietary tripod quick release plate, nikon neck strap, smallrig cold shoe to tripod ballhead, generic phone holder.
If Xapp wasnt retarded and allowed me to rotate the live view to landscape, the phone mount would actually have a decent use case, but for now its much better to mount a led light that i can tilt sideways.
