Canon 17-55mm 1.8 Lens worth it?

internal focus with USM, constant aperture, L glass

Pseudo-L glass, right? I don't see a red ring on that finger...

lol... no, its L glass, just doesnt have the L build around it. its the same low or ultra-low dispersion, fluorite coated element as the L lenses.

17-55 IQ in every measurable metric is better than the kit lens.

it comfortably out performs my 17-40L I just bought (but wont go on a ff body..)

by the way, is the 17-55mm better than the 18-55mm at f 3.5 @ 18mm? What does the 17-55 have over the 18 other than aperture?

and $$ too.

24-70 is not good enough to be a standard zoom for such good FF bodies Canon produced.
Sigma 24-70 is cheaper and even better than the Canon one from my research on web..
my question is I'm using a crop, would it be worth to switch to 17-55 from 24-105?
24-105 gives me better portrait focal range I think..but seems 17-55 has better IQ and aperture advantages..

You will going to miss the L lens quality, dust magnet as well as zoom creep for this 17-55mm f/2.8
