Panasonic just released the new firmware for the GF2/GF3/G3 cameras. You can download it here: http://panasonic.jp/support/global/cs/dsc/download/index.html. The new version 1.1 added the function for using the new power zoom X lenses, the Panasonic 14-42mm X lens and the Panasonic 45-175mm X lens.
Our reader Roderick Kar made the video comparison you see on top and posted some image samples on Flickr (Click here). And you can see the “transparent” version of the X lenses at DC.watch (Once on the site scroll down to see the pics).
According to Panasonic both lenses should be available in October but I wouldn’t bet on that. The Panasonic-Leica 25mm f/1.4 was supposed to be available in US and European stores in August but only very few lenses have been shipped to “western” countries in late September. And are now still out of Stock at Amazon, Adorama, B&H, J&R, eBay. Until now Panasonic cameras and lenses always have been in Stock 2-3 months after the announced availability month.
