actually, the adapter itself has no lock or anything

Ok now I see what you mean. Its weird, if I attach the lens to the adapter to the point it locks in and clicks, I can't change the aperature. I was hoping I could just attach this lens to the adapter, hook it up to the camera and be able to change my aperature without having to play with the adapter again. But it seems I can only set aperature before I put it on the camera. Very annoying.

Okay, this is really frustrating -- so the aperature only moves when you twist the adapter around? I really don't see the point of that. And depending on how far you twist and turn the adapter, you get a certain range on the aperature, it seems like it can vary from f1.4 to like f6 or if you twist the adapter one way it'll go from f11 to f22
I dunno, I don't think its the adapter, I'm just not doing something right on the settings or something. By dreamy I mean the footage looks kind of like a dream sequence. A lot of light, too much really is coming in so nothing is sharp unless I am filming a bug or something.
Sounds to me like you're just having reflection problems inside the adapter.
If you hold the adapter itself (no lens, no camera attached) up against a bright light source, are the internal sides of the adapter kind of shiny?
The cone of light projected by a 35mm film camera lens is much bigger than necessary for the m43 sensor, so you could have off-axis light hitting the walls of the adapter and bouncing back onto the sensor. Exact same thing happened to me when I used medium format lenses on 35mm cameras.
If you have any dead black, non-reflective flocking material, you could try coating the inside of the adapter. IMO, matte black paint is still too reflective.

On the FD adapter I bought (rainbowimaging) you can either lock the aperture or have it so it can rotate. If you put the lens on while the adapter is set to lock then the aperture will stay as you put it on. Simply set the adapter to open and it will function properly. Maybe this is the issue?
This seems to be it. However, it seems if you don't set the adapter to lock, then the adapter is actually loose on the body of the Gh1...am I right?
Also, there seems to be a small range of aperature settings depending on how far u turn the adapter into the GH1. I haven't been able to get a full f1.4 through f.22 stops available to me. This is weird. Anybody else know what I'm talking about? You seem to know...any more advice would be useful!
It sounds like the adapter is not very good, or comes with poor instructions!
My cheap FD adapter (from jiakgong on ebay) has a separate lock ring, and so do most of the others I've seen advertised. You set it to 'Open' to mount the lens then turn it to 'Lock' once mounted. After that, aperture control works perfectly. If you can't get this one working, it might be worth getting a different adapter.

Try and have a look at the instructions on this link:

This may be helpful to you or it may not depending on your particular adapter.
Good Luck!

Maybe this is the case. I'll find the link on ebay and post it here and maybe you guys can confirm whether or not my adapter just plain sucks

So this is pretty much the one (although mine is Cirrus brand)
http://cgi.ebay.com/Canon-FD-EF-Mic...29088?pt=Lens_Accessories&hash=item230414d380
Sounds like I have the right ones everyone has. Mine just doesn't have the words "open" "lock" on it, but I can twist the adapter left or right and here a clicking lock sound.
