how much front/rear focusing is unacceptable to you?

my 70-200 front focuses slightly even at full microadjustment. its probably less than half an inch. i used a page in a book as a scale and the line under my focus point was actually in focus. this was at 2.8 which i dont use that much. i mostly shoot outdoors (high f stop) and will typically manual focus on portraits. i very rarely print larger than 8x10 so a touch of pp sharpening will typically iron out the softness. would you send it in, in hopes that it may be able to be made right? or would you not worry about it?

All my lenses have slightly clearer planes behind the focus point. So I am tolerable with like 30-40% front is focused while 60-70% back is focused.

How do you know that the focus point was on a particular line of text? You do know that the actual AF points are a lot bigger than the little rectangles shown on the screen? And that the camera will tend to focus on the closest object covered by the AF point?

It really sounds like your camera may well be focussing correctly.

And the rectangle doesn't necessarily align perfectly with the actual focus point.
