Hi there,
No problems on the slow response my main concern was to get as much info to you as possible seeing as I had already made the purchase. To give you a quick update I actually took the unit in to Sony for a checkup and the focus thing you talk about on the left hand side was actually present too so they ended up replacing the lens to resolve the soft focus on the left and also to realign. The sad news is, that after Sony having the unit for 3 weeks the chromatic aberration is still no better :(
Follow this link to see some examples where it is quite terrible in my eyes:

I will only keep this page for a limited time so you can see the issues I have had.
