hopefully this is in the right section. i recently purchased a nikon d200 after having been shooting with a nikon f100 for years. when i use the 200, my camera seems to back focus. it focuses just slightly off of my subject. I have ruled out the cause being the lens as it happens on all lenses and all my lenses work fine on my d70. i sent the camera back to nikon, and while it is better, it is not perfect. i am used to getting a much larger percentage of focused pics when i shot film and i am just not happy. i attached a few examples. also, there seems to be an overall softness to my images, which combined with the noise is almost intolerable. any thoughts?
