Summary: I had to take this camera back as the 14-140 lens is very noisy. It makes a constant whirring/churning noise and it didn't seem possible to switch off whatever it was doing. This noise is audible when in a quiet room and as such is picked up on video recordings. I tested the 14-42 lens and it does not suffer from this problem, it does however make a clicking sound. I can only guess that these noises are created by the gyroscope in the lenses.
Summary: Really disappointed, especially with flash, thought it would pop up automatically when both in low light and in intelligent auto mode. Actually thought camera was faulty but camera repairs had a look and said its not designed to pop up automatically, manual button has to be pressed which is a real pain. Wish Id gone for the DSLR I'd fancied and not made compactness a priority.
