Just received my Oly 45 in the mail today. Very excited to have this lens for portrait work, and it completes out my prime kit for now (14,25,45). I got an adapter for my Rokkor-X 50mm last week and I have already got the idea of the FOV for this focal length. My concern is that the focus ring seems to have a little back and forth play on it. Does anyone else notice this in their lens? It doesn't cause any issues whatsoever, but I wouldn't want to become even more loose over time. My panasonic lenses are very solid in this respect so I just want to get a little feedback since I bought it new. Thanks for the input.
