Bah, first day of our trip to Indonesia with my new Sigma Art 30mm the NEX-5r decided to 'reset' the lens every time I manually focused/moved camera too fast/touched the lens/looked at it funny. Cleaned the contacts but the problem persists even with my Sony lenses. Still managed to get some good photos but it was always tenterhooks whether the lens would reset at the critical moment!

Very professional guy on the phone - he made me laugh by enthusiastically guaranteeing a minimum turn around time of 10 working days. When I asked him what the maximum was he got a little confused 24 hours later and still no returns form in my inbox so off to call again now.
