This is insane, a new macro lens that goes to 5:1 and has built-in LED illumination. So accurate is the focusing it is paired with a holder to keep the subject at the exact distance required. Think of this as a microscope rather than a macro lens. Results look extraordinary.
Here is a translation of the Impress article on this lens. And here is the manufacturer's page on the Nanoha.
Projected price is 50,000 yen (about US$630).
