Hi all. Thanks for the many welcomes I received. On my last post (have I a problem with my D7100) I certainly have.Bought in mid May this year,I contacted Nikon and my supplier as images where not as good as the D7000 I traded in, I sent images to them which they said where acceptable. Holiday snaps to me were dark and muddy, to satisfy myself I sent the camera to a Nikon recommended repairer. That was four weeks ago, a fault with the aperture mechanism seemingly and they have no idea when parts will arrive for repair. Thanks Nikon for nothing, feel very let down, expected more from a £1000 dslr.
