This distortion is due to you pointing camera upwards. Can correct in PP if not serious, otherwise top may look stretched.
 

yap it's normal. use software like lightroom, captureone etc to correct it.:)

thanks so it can be pp.. think i really must go and learn lightroom or ps...

thanks i will try to do it in lightroom and see how it go.. thanks so much
 

btw, it's called "keystone effect". You can read more about this on google..

thanks sky, i trying to dl the trial ver of lightroom 1st.. i will google this :)
 

if you don't want the building to lean around, try not to tilt the camera too much or better still, get a tilt-shift lens.

The keystone effect is not caused by the UWA lens, but by you tilting the camera up from horizontal position in order to fit in a tall building or structure.
When you tilt the camera up, all parts of the building are no longer the same distance from your camera. The base is nearer to you than the top. Hence you get converging lines. It's a similar phenomenon to photographing a road. It appears to converge in the distance.

nope :)

get a hotshoe spirit level if that helps. Easier to see if you are mis-aligned. Alternatively if your camera viewfinder gives you gridlines, can use that to align horizon + the vertical sections of buildings.
Take note that the sides of MBS are not straight vertical.
