Comment:

Distinctly uneven performance across the frame with great resolving power and contrast in the center and mediocre to poor corner performance that doesn't improve much on stopping down somewhat diminishes this lightweight super wide prime's potential for fine art landscape photography, but it's still good value and certainly a welcome addition to the Nikkor family.
