Micro 4/3 to Nikon Fotodiox Adapter Troubles

So a few weeks ago I purchased the $45 fotodiox adapter for the AF100, I read some good things about it and it was better than dropping $300 on a fancy adapter. This is the adapter that allows you to control the iris. Well, when I focus my lenses, even if they have nice smooth focus, the iris will change when I turn the focus ring because the lens won't lock 100% tight into the adapter. It locks in but there's a little wiggle room, this is with both my Nikon AIS lenses and a new Rokinon 85mm I just got today. Has anyone else had this issue? I haven't been able to find of anyone else having this issue but I 'm wondering if I go ahead and get the more expensive adapter...

Wiggle isn't the biggest issue with that particular adapter (although it is an issue). Take the adapter off the lens and camera and hold it at an angle toward a light source and then look at the inside, do you see a reflection? So does your camera sensor.

Hm ok, I'm new to this whole adapter deal. What's my best option that will allow me to control the iris externally and won't have and wiggle when the lens is mounted? Any suggestions?

I managed to find a used Novoflex for under $200. If you choose older Nikon lenses you can use the aperture ring they are built with, this is the best option but it eliminates some of the popular newer zoom designs.
 
Most of the Fotodiox adapters have a little play because the mounting flanges have adjustable thickness to make them just right. Look inside the adapter: you'll notice very very thin slits in each of the three mount flanges. Pry these open ever so slightly with a fine flat screwdriver and voila, nice tight fit. Trying to solve the issue with a paper shim is temporary and counterproductive (it will change total flange distance and may affect focus)

As to the shiny innards, that's why God invented matte black spray paint.
