Hi, I just purchased a brand new Nikon D3100 with AF VR 18-55 mm lense. After unpacking and putting the camera together with the lense, i realised after i tried clicking a picture through the viewfinder that, i was not able to focus because it was all blurred. I tried adjusting the little knob near the viewfinder, put it on AF-S mode, still the view from the viewfinder is blurred. But the view in the live mode is crystal clear and pictures clicked in either of the modes are also clear. Can anyone help me else if no other option is left than i will have to get it replaced.
