do consider this range 17-40, 24-105, 100-400 & 180 macro add the 10-22 if you have more to burn

Standards change for the better IMHO. Even our own!

Some points to take note.
Cameras improve a lot year by year so this item is probably not a good idea to chase if you have a limited budget.
Lens quality improve only very little year by year so it's ok to buy a really good one that you like.

Some rambling here about 50mm's
Having just a 50mm for me is very limiting. You may want to pick up an additional lens like a good 17-50 or 28-70 just for variety. Then why buy the 50 in the 1st place? lol.

50mm i lowlight is not particularly impressive because of the low dof and normal perspective. [better somewhat with apsc crop though]
It's great for manual focussing and AF because scene looks very bright through the viewfinder. You can also make it into a macro by reversing it or adding an extension tube.

budak got it spot on. myself spent a bundle on the EF-S 17-85, it performed horribly at the wide-end, which is the whole point (to get wide angle shots) of getting a 17mm zoom to begin with.
