Eric,
As Jack wrote, - 17-70/4 could be an option for you (if the price is
affordable)
I bought it as it gives me that reach to 70.
It is not the sharpest lens at the longer end, so, if I need 50-70 at the
best quality, I switch to 50-135/2.8. But it is reasonably good
nevertheless.
I think it is still my most frequently used lens.
Its angle of view on the APS-C is 79-23 degrees, while 16-45 is 83-35.
So, I think the amount you loose at the wide end is not _that_ big.
Both lenses have the same (relatively small, 11"/28cm) minimum focus
distance.
There is also Sigma 17-70/2.8-4 out there. I don't know much about it.
Now, if you are considering a budget alternative to 20-40 - just a wide
zoom, I'd just point out that there were several Tokina AF lenses
that were 19-35 or 20-35).
Initially, it was in two flavors, the more expensive ATX Pro
(20-35/2.8), with better optics and he budget version 19-35/3.5-4.5.
It is still available on e-bay, and typically goes for $130-150:

I am also seeing 20-35/3.5-4.5. I suspect it is a later version of the
19-35.
Tokina 19-35/3.5-4.5 was my first wide-angle lens, yet on the film body.
It is quite good, although not perfect. Of the con's, I remember that it
was prone to flaring in the direct light.
I still have it, but haven't used it for ages, so, I don't know how it
works on the modern bodies (I believe, I used it just a bit on *istDS
without complaints).
I don't know why I am still holding to that lens, for now, my 17-70 covers
all what 19-35 can do...

Well, when isn't cost a consideration? I'll put it this way: I'd like to have
a 20-40/2.8-4 limited but that's beyond my means. A 16-45/4 is much more
affordable and I might go up to double KEH.s price for it if there was
something that might be better for me, e.g., something as wide as the 16-45
but with a longer zoom range.
It seems that my photography requires either that or a telephoto and not much
in between. So I.m not especially interested in trying to accommodate all
that in one lens. I just want a good wide-angle zoom.
So, should it be the 16-45 or is there something else I should consider.
Thanks,
