In my case it is shifted closer by a small amount. Ok....after writing that I just did another series of tests as I was going to test fewer focus points. Since it is daylight now I had opportunity to test samples against bright backgrounds (livingroom window with daylight) and it actually was working fine (!!!). Then I thought ok it is a low light issue. So I went into the kitchen with the lights out and shot a few dimly lit objects at high ISO (so camera shake isn't a factor), and I was shooting f/1.4 and it was locking onto very small objects in the frame without problem. :confused-new:  I tried different ISOs just to be sure. I would be watching where the focus points fall on the viewfinder, and it locks on precisely....regardless of whether I shoot 1.4 or 2.8. Man, my camera is possessed or something? I'll have to try shooting again this evening. But I was shooting at like 6400 ISO with 1/8th second exposures in the kitchen and it was still locking on where I saw it locking on. When I was on my first shoot with the lens on Thursday I kept it at f/2.8 of course so I have no idea what happened between when I first reported this and today. But I'll keep an eye on it. But my goodness, when it works, what it can do with selecting part of a subject, no matter how small, and rendering it within such a narrow depth of field....wow.</blockquote>
