I have a problem. I bought a used NEX6 from Amazon Marketplace. The camera was sold as being "Used - Like New" condition, and whilst it looked great with no obvious marks, it did have an odd behaviour, which I believe to be a fault and returned the item as faulty. The problem being, the seller is saying it's not a fault, and because of this, I have lost out on both postage and return postage. Amazon of course have taken his word.. I'm hoping some NEX6 owners can confirm is this is regular behaviour or not. The problem is with the control wheel (the silver dial under the mode dial). It has a notching mechanical action. The problem with the camera was that there was one notch on the dial where it wouldn't register with the camera, the next notch would then double advance. It would happen on the same place on the dial each time around. It was most annoying on picture reviewing, advancing two pictures at a time, rather than one. But it did the same on all other functions too, setting apperture and shutter speeds for example. It might sound like a subtle problem, but it did drive me wild with frustration, and I also checked it wasn't me, by getting someone else to try it out, and they had similar problems. is this normal behaviour with this camera? Anyone else experienced it? Many thanks.
