Fisheye adapter
 

So I went out and bought the 16x9 inc. fish eye adapter for the z7. When I screwed it on the lens, everything is out of focus. What setting am I missing? Macro?

I had the same problem Micro Focus needs to turned on or off. Try both settings I sold my Z7 so I can not test it.

I found the marco needs to be turned on and the only way to turn it on is by leaving it in auto focus. That sucks because if the iris is all the way open, there's actually a depth of field effect and won't focus on anything close...... ironic really being a .4 fisheye adapter.
