A definitely need some thoughts from this forum. Just received my D600 with the 24-85mm kit lens. Did the basic setup, and took some shots around the house. A major disappointment as pics were blurry. I then tried 4000 shutter speed. Same reslt.
Next I went to my 50mm 1.8D lens. Same result. Next, I tried my Nikon 35mm 1.8 DX, saved from my D300. Now that lens was always sharp.
Still, pictures that are very very soft. These were all jpgs. I really do not know what to do. Am I missing something? Do I send it back? Or is there some setting up to do that will fix this problem? Your help would be appreciated. Nothing like having my expectations dashed so badly.
