The new Panasonic Leica 100-400mm lens will finally start to ship next week on March 15 according to BHphoto.
Daniel Cox just returned from Japan where he met with the Panasonic Lumix team and spent ten days photographing Japan’s Winter Wildlife. Most of the work was with the Lumix GX8 and the new Leica 100-400mm zoom. You can see the image gallery here http://archive.naturalexposures.com/proofing/C00003nDou.nKOU0/G0000gFSGHEV7FMk
