The Panasonic GF5 X is now no more available at Amazon (Click here) and Adorama (Click here). There are still a few left in Stock with the 14-42mm (non X) lens. I have no final specs of the GF5 successor but I have been told it is a minor upgrade and nothing super exiting. The new successor won’t be smaller than the current GF5. It will be interesting to see if Panasonic will also launch a fixed lens RX100 competitor later this year. That camera will be the smallest camera with FT sensor ever made to date.
That said the current GF5 can be found for a very good price ($449) with X lens and new on eBay US in Black (Click here) and White (Click here).To get notified on further eBay US price drop login and save this search on Slidoo (Click here). And here is the link for the Slidoo Europe search (you can change country in your settings).
