My Rainbow adapter arrived for my Canon lenses and my E-P2. It's very snug and I have to remember that it toggles back toward the camera to remove it from the lens it doesn't pull up to release the lens. I knew that because I figured it out before putting it on but I still wanted to pull it up when I removed each lens. I aaamm naught a smaarrt maan. For around $50 the quality and fit are very good. I've only taken a few with the 50 1.2 and 135 in very low light but will post some in the subforum when I get something worthwhile. Setting the aperture on the Canon body and removing the lens while pressing the DoF button is a nice work around for the lack of an aperture ring on the lens. The lenses feel surprisingly balanced on the camera but the correct focus requires surprisingly small movements of the focus ring to lock it in while using the evf. Hopefully I'll be able to post some shots this weekend and evaluate the color rendition and bokeh as compared to the olympus and pana micro 4/3 lenses in my lineup.
