Shootout: Olympus SHG 14-35mm f/2 ED vs Leica 28mm M Lenses

Continuing my Guide to Mirrorless coverage of lens performance on the subject of using Leica M lenses on the Olympus OM-D E-M5.

Can the $4300 Leica 28mm f/2 Summicron-M ASPH or $2200 Leica 28mm f/2.8 Elmarit-M ASPH beat the $2300 Olympus SHG 14-35mm f/2 ED zoom lens?

In short, just how good is the Olympus SHG 14-35mm f/2 ED zoom?
