The focus chip is really not worth it, other than having some EXIF info tagged to each image. The DoF is so large that the AF sensor will not give you consistant confirm. I pulled it off the 14mm and re-mounted it on the 85mm f1.4, where it actually helps out quite a bit.
Another point about the lens (besides the focus scale being way off infinity), there is a sizable focus shift going from f2.8 to a working aperture like f5.6-f8, so use LiveView to confirm. I agree with the software corrections, as they do work great. The lens is a bargain, along with the 35mm, and 85mm. You just need to work slower and smarter...
