New Olympus 25mm f/2.8 macro lens patent May coming at photokina?)

Egami spotted a new Olympus patent describing a 25mm f/2.8 macro pancake lens. It’s also collapsible, when you use the macro function the lens gets larger. As you may remember last week there was a rumor about a possible 25mm f/1.8 lens.

At 25mm focal length we can chose between the [shoplink 23110]$599 Leica 25mm f/1.4[/shoplink] and a [shoplink 15659 ebay]$900 Nokton 25mm f/0.95[/shoplink]. Both options, a pancake 25mm and a cheap and fast f/1.8 variation would be a welcome addition to the m43 lens system.
