with the shown images, i got a fair idea how wide lens are used with big apertures. thank you everyone for the sample pics. now i will finalize the budget and then shortlist the lens.
till then i would like to know suggestions from all you guys, for my 600D. also, is it worth to get only body and 2 lenses. like a wide and a regular

say for eg, a 10-24mm and a 24-70mm, something like that.

no idea how much it wil cost me, but just thinking that way.
