I took some portrait shots the other day and was disappointed at how soft they were, so I did some investigation, this revealed a soft focus issue when focusing using the far right focus point (see image).

Comparison of left, centre and right points.

Naturally I'll be contacting Nikon service (whom I've had fantastic response from with regard to the oil/dust issue).

I find it particularly annoying having the right focus point faulty, it means I'll have to focus/recompose all the time when shooting in portrait orientation.

Test shots were on a tripod with focus chart stuck to wall, using pan head to use alternate focus points.

ISO 400, 1/80th second, F 2.8.

Any comments regarding the validity of my tests etc are welcome.

Hi, you say you are rotating the camera on a panhead to move the focus points over the target, right? At f/2.8, 70mm your DOF is quite thin and you are placing the sensor at an angle to the (hopefully) flat chart. Not the best for a sharp image.

Besides, the left side is much softer than the other two,
