Hi Kirk, Hi Dom,
Thanks very much for your feedback, it's all really informative and helpful.
This morning by a stroke of luck the lens came unstuck. It seems to be functioning perfectly now! I guess I was a little premature in posting but all the information on the camera is great nonetheless. As you mentioned, maybe something small was jamming it and I knocked it loose finally.
I'll still take it in to have it looked over and serviced. Will let you know if they find anything interesting and, eventually, results if you're interested!
Cheers,
E
