Ok, busy putting the 18-200mm through it's paces on the NX300.

I am getting this awful crunching/grinding noise in lens priority mode on focus.

So I am not sure this is an aperture problem, as in lens priority mode, aperture should remain locked - unless the problem is that is trying to forcefully adjust it when it is locked...

Put it on the NX1000, and don't seem to suffer it there, but lens priority mode is different on the NX1000.

But the lens ALWAYS makes the crunching/grinding noise on startup on either camera.

I can still hear the noise I was originally referring to on the NX1000, which is a softer noise, but this noise I am hearing on the 18-200mm at moment is a much louder crunching/grinding type noise. And there were times on holiday the NX300/lens combo would get caught in this cycle of making this crunching noise, and it looked like it was trying to adjust aperture, but maybe that wasn't it (that wasn't in lens priority mode though, but any mode), and the only way to stop it was powering down (but sometimes having to remove battery completely) I just don't know whether this is faulty lens, or firmware issues in cameras?
