This was reviewed to be a good sharp lens for the $ but mine is quite bad especially at the edges. My DA 16-45 blows it away in the sharpness department. I'm wondering if I have a bad copy or is this just not a very good lens?

.. better say exposure time, is only 1/15 of a second.

So of course it blurs.

But the blur (likely related to focus not motion) is not uniform across the whole frame

Decrease exposure time to at least 1/80 sec, and then compare the results.

Not not needed in this case as the issue is with the inconsistencies across the frame. And the setup may not have been handheld and the building doesn't appear to be moving

My opinions are my own and not those of DPR or its administration. They carry no 'special' value (except to me and Lacie of course)
