If you won’t wait Amazon, BHphoto or Adorma until they have the lenses in Stock I will show you a little “trick”.
Third party resellers do have the Lenses in Stock at amazon. But normally it is difficoult to find it:
Click the link to get the Panasonic 45mm f/2.8 lens.. Scroll down a little bit and you see the Lens in Stock via J&R for $899.99. Haystack Electronics has it also in Stock for $849.95.
And click here to get the Panasonic 20mm f/1.7 lens via GadgerClick or Leo Li.
