If you've got a Panasonic GH2, or other Micro Four Thirds camera, you'll know what this lens is. It's been tough to track down lately when they went out of stock because it's just that awesome for a MFT camera. Luckily I grabbed mine months ago, and it's been on the GH2 as the primary lens. My GF2 also came with the 14mm Pancake, which is another popular and highly recommended lens for these MFT cameras. More than likely this new shipment of the 20mm won't last very long, so if you've been waiting patiently here's a chance.
