I decided to move digital and buy Canon 20D camera. My next step is to pick a good prime (17-18mm equivalent to ~28mm angle of 35mm cameras) for landscape work. I find only one prime lens in this range - Tokina 17mm f/3.5 AT-X AF PRO and couple of wide zooms:

Canon EF 17-40mm f/4L USM
Sigma 17-35mm F2.8-4 EX
Sigma 15-30mm F3.5-4.5 EX Aspherical DG DF

How Tokina compares to this zooms? Maybe Canon 17-40 is better than Tokina prime? Please provide some recommendations. My budget is up to $600.

The problem with the yellow is dependent on what color scheme you choose. I'm (currently) using the default white background with black text. In this situation, the yellow can't be read without hilighting it.

If you use the white background with black text (another default) the yellow would be readable.

As to the question at hand, the 17-40 is a very nice lens. I like mine a lot. You might find that 17mm isn't wide enough, and then the sigma with the 15mm wide might be better.

I don't know which of those is better optically, sorry.

Since you mentioned you use the 17-40, I am looking at buying this lense. Are you able to use a circular polarizer with it (with a DSLR) or is it still too wide and you don't get the appropriate affect?

I have the 17-40L as well, and use it with a circular polarizer. That's not a problem at all. On a 10D with its 1.6x crop factor you don't need a thin polarizer (probably necessary on a full frame camera due to vignetting). Here's a link to a picture I took with polarizer on the 17-40L.
