Red Rock has done it was a product called Live Lens:

It's steeply priced at $495 US, but it's also upgradable.

Took them long enough. They announced that thing back in January, I was half expecting it to be just vaporware. Now, I am just wondering if you can attach the lens to any camera you want or is it only compatible with the M2? I would watch the video, but my sound card recently fried so I can't.
