Hi all, This lens is crazy. It's enormous (almost comically so), it's has the largest filter I've ever seen (82mm!), and it's S-H-A-R-P from end to end, wide-open. Includes an 82mm (tiffen, I believe) UV filter. I've never used anything quite like it. I've included multiple pictures and a full size sample from my GH1 taken at ISO200, 30mm, f/2.8 so you can see just how incredibly sharp this thing is. Link to full resolution (untouched) JPEG Price is $210 obo shipped and PP'd.
