Some confusion here. The 16-35mm is better than the earlier 17-35mm -
both are F2.8. You are thinking about the new 17-40mm f4 which is
better than the 17-35/2.8 (and about the same price new as a used
17-35!). It is comparable to the 16-35mm being a touch sharper at the
wide end and a tad softer at the long end - by an amount you'd never
notice. Therefore, the choice is paying your money for the extra
stop, which a pro will do and I could not. I've used the 24-85mm and
it is very good on 35mm - it was designed for APS (Canon IX bundle)
and the smaller frame showed up its limitations so I assume that the
same limitations apply to a digital 1.6 factor image but it is a long
way ahead of the consumer grade zooms. It is also vewy, vewy slow.
And I will take that bet.
I am no speed bigot - I had better results on one shoot with the
50/1.8 than the 50/1.0 possibly because the f1.0 is hard to use well
but it IS soft wide open - speed isn't everything but a pro will
sometimes accept a small performance loss for an extra stop or two
and a better view in the finder.

Yes I do - because I want to use a 1.4X converter with it. And it is
a joy to use. And there is no IS version of the f4 yet. Oh and
someone pointed out the 77mm filter size I think, but Canon have
obligingly used it as a standard on these beasties so my short and
long zooms use the same pola - how nice. If weight is a factor, I'll
use a rangefinder instead.
Now I'm just off to visit a bloke who owns the Canon 200mm f1.8 - go
on, ask me if I'd carry that weight around! Duh!
