Which adaptor for EOS lenses?

I have a few EOS prime lenses that I would like to use with my GF1. I understand that focus will be manual etc, but I don't know anything about the types of adaptors available. Can anyone recommend one?

Thanks in advance.

Good question, thanks for clarifying! No aperture control -- didn't even know that was a possibility, actually. I shoot wide open 90 percent of the time by choice, it wouldn't be much of an issue for me, anyhow.

It might be more work, but if you have a camera that the EOS lens is native to, you can fool it into an aperture you want (I think).

Put the EOS on a native body for it. Set the camera body to aperture priority and set the aperture you want then hold the shutter button halfway. While holding the shutter halfway, remove the lens. This should leave the lens in the state it was set to. Then put it on your adaper ring and mount it on your other camera body.

Because the aperture is stopped down, the live view may be darker than usual and hard see in order to focus.

I just thought up this trick as it is similar to the process needed to change aperture when reverse mounting lenses.

Disclaimer: I don't own any EOS lenses and have no idea if this will work, but it may be worth a try if you absolutely need a certain aperture value... Thoughts??
