This is a new larger image of the just announced 30mm macro lens.
Panasonic writes about that lens:
The new 30mm/F2.8 macro lens enables not only life-size macro photography but also offers further versatile styles of capturing photos, such as landscape photography thanks to a focusing distance of 60mm (35mm camera equivalent). For high precision focusing in macro photography the new lens also supports 240 fps high-speed AF, while integrating optical image stabiliser. It features a sophisticated exterior design in metallic finish for the stylish appearance.

I was at the Photokina today and Pansonic had a mockup of a 30mm lens with the label “Lumix G macro”. There was no further explanation and nobody at the booth could give me details. In fact they were surprised by the display themselves ;).
There is no info yet about price and availability.
