Yah, second one looks Soft or camera shake. I don't see that the 2 photos share a common fault. Still not on the best monitor for comparison though. If you could post a couple more, then we will have more to compare. Nothing definative yet though....
What's the EXIF data - Lens, f stop used?
what settings are you using with the AF system? The new system is so complex that you may be using multiple point without knowing it. Just to test the sensor try shotting with single point AF in the middle and see if it feel still soft?Just a suggestion...
