16mm performance ?

Thanks again folks .. I was looking at the photozone samples where it was awful away from the centre at F2.8 and not up tp much at F5.6 - having seen far better performance from the ever slammed NEX16 at all apertures I came to the conclusion the NX one was a dud

Maybe like, the NEX lens there is severe sample variation .. thanks for the images and opinions, it`s crossed off the Ignore list
