1/60s - f/5.6 - ISO 100 - 17mm
This is the widest you could get with ordinary lens. In this case, 17mm. Yup, it's the same focal length in "The Tower" I shot earlier.
1/800s - f/5 - ISO 400 - 10mm
This is what you get with 10mm on the super-wide lens. If you have ever been to Melbourne Central, you could definitely appreciate the vast angle of view in the shot.
Technical Note: The duller colour in the first pic is not the fault of the lens. It was because I didn't bother processing it because it's not a "good" photo. I just took it to compare the focal lengths.
