The Sony looks and acts similar, but I'm thinking Sony may have tweaked this lens a little (in regards to sharpness), that's off the cuff for now though.

Here is the general location of the corner corps in the full image.



These crops are from the red box in the bottom left corner of the image above, I don't normally show the whole image. I start off at the widest aperture, then stop down in one stop increments up to where things don't get any sharper, usually around F/8-11. On zoom lenses I show crops from the widest setting, and the longest setting. I list the focal length above the boxes. These shots are almost always taken at infinity focus, and always re-shot at least twice to confirm accuracy.
