The last image was taken at 95mm and is pretty sharp. This image was taken towards the wider end at 22mm. Again I can't complain, it's ok for my purposes, since most of my images are taken for web viewing only. I rarely print big and when I do print it's mostly in the form of photo books.
You can see the effects of keystoning, where the buildings tilt inwards. I was down on my knees with the camera pointed slightly upwards. I wanted to get the statue in the bottom with the water fountain and also the buildings with the sky reflection. Normally when I take this sort of image I tend to exaggerate the effect but here I couldn't get down low enough to exaggerate it further. If you're going to get this effect then exaggerate it as much as possible.
