What Lenses to Buy for the Mark III?

I am first on the list at a camera shop for the Mark III. I am coming from a Nikon D200 and don't know much about the Canon lenses. I know I want them to be USM and I know I want one to be the 100-400mm USM.
Can anyone suggest a couple others? I would like a good portrait and scenery lens and a good walk around lens like the Nikon 18-200VR.
I am new to nikon so I would appreciate any help.

24-105L 70-200 IS L makes a great combo

16-35L or 17-40L good wide angle choices

35, 50, 85, 135 nice primes

The 1D 2's and 3's are in the weird 1.3x crop factor where the standard good walk around lenses 24-70 and 24-105 may be a bit long on the short end. The EFS lenses do not work on the 1D3 much in the way the DX lenses would not work on the film bodies. So you'll probably need to pick up a 16-35 or a 17-40 to get around the 20mm mark, and either the 24-105 or the 24-70 for general purpose shooting. "L" lenses are the premier Canon lenses and can be identified by the red ring on the barrel. For portraiture primes, the 85mm 1.8 or 1.2 are excellent along with the 50 1.4, 50 1.2, and 135mm.

the-digital-picture.com and fredmiranda.com are good places to find review for various lenses.

I don't think Canon makes any one lens to replace the 18-200VR. It will take two or even three lenses. How good can a 10x zoom be?

Tony,

Do note that the D200 is a 1.5x crop camera and the 1DMkIII is a 1.25x crop camera. Canon does not make an 18-200 superzoom, and the closest you will get is a 24-105L. The 18-200 on the Nikon gives a field of view of 27-300, and the 24-105L gives a field of view of 30-131 on the 1DMkIII, so they are very close on the wide end, but not so much on the long end. Also note that the Nikon is a variable aperature lens, with up to f/5.6 while the Canon is a constant f/4.0 aperature.

Portrait and Scenery generally don't fall in the same category. The 24-105L will suffice for both, but the bokeh isn't the best. If you want to lose some focal length, and IS (which is very hard to give up), then you can go with the Canon 24-70L. However, the 24-70L and a 1DMkIII is a HUGE and Heavy package, and wouldn't necessarily bet the best walkaround out fit.

I think Corey gives you excellent advice.

Canon 17-40L for landscapes
Canon 24-105L f/4 IS for walkaround or 24-70L f/2.8 for portrait
Canon 70-200 f/4 IS or 70-200 f/2.8 IS (depending on budget)

That 3 lens kit will be very flexible

Get the 17~40mm f4 L and the 24~105mm f4 L IS if you don't need f/2.8s
Then with 3 lenses you have from 17mm to 400.
If you need f2.8s get the 16~35mm and 24~70mm instead.
If you need wider for a UWA get a Sigma 12~24mm EX DG, but know that it's a rear filter.

second it... but maybe with the mk2 16-35.

EF 28-300mm f/3.5-5.6L IS USM will give you similar range to the 18-200.

...the 1DMkIII is a 1.25x crop camera.

As I understand it, the 1D, 1DMk2 and 1DMk2n are 1.25 crop factor formats. The 1DMk3 is 1.28.
