Unsharp pictures

Hi again,

I just expanded my equipment with a Nikon D750. So today in the early morning hours I took some pictures at the airport. When I saw the pics at home on the PC screen I was very disapointed. I saw that nearly 3/4 of the pics were motion blurred/not sharp. Can you help me to avoid this mistake?

Camera setting:

Nikon D750 + Nikkor 200-500VR

ISO 400-160

f7,1

exposure was between 1/400 and 1/800

VR set on (normal)

if you need further pictures or informations please contact me

with best regards

Tobi

How was set FOCUSING MODE ?

It should be CONTINIOUS, FOCUSING PRIORITY, CENTRAL FOCUS POINT...

Shutter speed 1/400 neds ( depending on the speed of the plane ) panning technique..

Hi Igor,

Focussing Mode is already set to AF-C. The Shutter speed (on sunny days) is usually around 1/1000 and 1/640. I always pan with the plane even if it´s taxiing slowly. The VR on my lens is alway set to ON and NORMAL. I can´t really understand what I´m doing wrong at the moment
