I borrowed this lens for my trip to Hong Kong and Macau. Managed to do some test shots in the Hong Kong Airport. You may compare the difference between 10mm and 22mm. Since the picture are taken indoor and some in the night, ISO was set to 400 and hand hold without tripod. You will see some noise in the picture if you blow up to 100%. The picture are pretty distorted at the wide end but it creates the effect which otherwise will not be possible.

No post processing is being done to the picture here except the resize to 35%.

I also included some pictures taken in the Macau and Hong Kong using this lens.

The pictures are best view with original size.
