Hi Mick
I have since been told by my dealer that after many varying dates, that the lens could be delivered by July/August!
Having noticed that the LCD screen was starting to blister (the outer layer was becoming separated from the screen) it has now gone away for repair! Having checked out this now common and expensive fault on the internet, it has shaken my confidence in this terrific product. So will now consider replacement! Sad as I notice that the LCD problem effects many other models, even the 7 range!
Sony need to take note of their reputation.
