I recently attended a Sony Roadshow where DOP Philip Bloom presented a seminar where he showed some examples of his work using a 35mm lens adapter. The shallow DOF obtained using this combination was breathtaking to my untrained eye when shown on a large hi-def display and when projected.
The trailer he showed was of an upcoming doc called 'One Nightshift' which I can't find on the web but here's another example:

and a smaller version: http://www.philipbloom.co.uk/Philip_Bloom/Piccadilly_Furs.html
and here he explains the advantages of using the adapter:

pretty cool if you're lucky enough to already own and EX1 (or indeed EX3!)
