Hi, I'm in the process of replacing my old AI-S 400mm f/3.5 (awesome sharpness, but MF only) with my newly acquired 200-400 f/4. VR II. I am experiencing some problems getting the desired sharpness. Maybe some of you can help me. I tried to fine tune the camera-lens combo but it seems I get the best results setting the value of 0 (zero). I tested the combo by pinning a newspaper on the garage door and shooting it from a distance of approximately 15 meters (tripod, cable remote release, mirror up, VR off). Now I will post some real life examples, so you can judge them and help me. The tripod I use is the same old Manfrotto with the gimball head I was using for my 400 f/3.5, even with the TC301 attached, so I am sure the tripod is not the problem. In one of my older posts (http://www.photo.net/nikon-camera-forum/00bIW5) you can see pictures made with this combo, they are sharp. My settings were: f/4, 1/250 s, AF-S Single, ISO 400, VR ON, except for one picture where I used 'Dynamic 21 points'. I hope someone can help me made my photos better. I know there is a learning curve but I try to make it not too steep Regards, Miha. First photo is of a static object, focus point in the center.
