True, if I had an NEX I would own the lens too, its performance is on par with its pricing, for the money it would be worth it to own.

To be honest at f8 + both lenses look pretty sharp. Both have fairly soft edges at max. aperture, but that's a stop larger for the 16mm, so you'd expect it to be worse.

If the photozone results are worth anything, the Sony is weaker in corners even at f/8. Whether you need sharpness there is a different issue. More worrying is their report of chromatic aberrations. I didn't see much CA on the DA15 and I think this is one of the strong features of that lens and a good argument for picking it even if you have something like the DA 12-24 - the Sony looks like it reaches ranges that no other lens has reached before Can someone who has the 16mm validate if CA are indeed so severe as reported by photozone?
