It\'s basic future proofing.
Ok, so how about a slightly more relevant example. If you have two $1000 25mm f/2 lenses and they produced the same level of distortion in the image, and one was corrected optically, and one was corrected digitially, and the results are identical except that the digitally corrected lens has a flatter field, less spherical aberration and slightly less longitudinal CA (axial colour), which would you chose?
As I said above:
The optically corrected one. Because it\'ll be more friendly with a competing system. For instance if someone made a film camera that could take FE lenses. Or perhaps Sigma makes an FE clone mount camera? Or if I decide to adapt the BATIS lenses to fit my (insert future camera here). Think about it from an M perspective. Why buy an M lens, to find out once adapted that it\'s shitty? Then you\'re having to correct all your images.
It\'s basic future proofing.
