So taking the popular and common 24-70mm focal length range:
You'll probably notice that over the years, zoom lenses have dwindled from 35-70mm zooms down to 28-70mm zooms, and finally settled(ATM) at mainly 24-70mm ranges.
I dunno if Canon have these focal length ranges in any of their zoom lenses, but Nikon have had over the years, and the lenses have got better with each incarnation.
Optics technology drives the numbers game, and if were reasonably)possible, I think manufacturers would ideally love to make for us a nice well rounded all purpose 10-1000mm f/2.8 lenses we all seem to dream of.
I guess in the years to come, those 24-xx lenses will look more like 22-xx mm or 20-xx mm lenses.
