The Olympus 12mm F/2.0 lens for MFTs looks like it might be a good performer underwater. Is anyone using it yet with an Olympus housing? How well does it work?
On the downside, I note it is more expensive than the camera body :-(
If you have a look at the latest Underwater Photography magazine #65 you will see an entire article on the above lens and Olympus' housings. . .
