Images not sharp in Wide Angle Lens.

Hello all,

The pictures I take with my EOS 7D and Tokina 11-16mm f/2.8 AT-X Pro DX II is not that sharp. A sample image is attached with this.

The settings I used for this is:

f8, 1/320 sec., Center-weighted average, 100 ISO, 11.0 mm, no flash or tripod.

The picture 'looks' clear in mobile devices. But if you zoom it all the way to 100% there's a drastic quality loss. This is a processed image - Just the highlights were dropped down and a bit of shadow has been lifted up.

I would like to know what is degrading the quality. Is it the crop sensor or the shutter speed or any setting or my lack of knowledge in wide angle photography?

I want to learn and use the lens efficiently. Please guide.

Thank you,
