Hot shoe adapter on top of the handle.
 

Perhaps someone here could point me where to buy this tiny screws so I could mount the hot shoe adapter on top of the handle. Out of 4, I only have 1. Tsk! tsk!

I know this is a month old, but what exactly are you looking for?

The Z7 has two cold shoe mounts. One near the mic which is detachable & one near the view finder which is threaded, but you can put on a cold shoe mount on top of the thread.

I would say if you're missing the screws for the cold shoe, just go to your local hardware store & look in their screw / bolt section.

Take the camera into a jeweller mate...

Hmmm... jeweller, good idea for tiny screws. I'll have to keep that in mind.
