Canon 20D (1D or 1D MarkII not necessary)
Canon 17-40mm f/4.0L ($650. Canon 16-37mm f/2.8L --$1300--is not necessary since this lens will be used mostly outdoor where light source is not a problem)
Canon 70-200mm f/2.8L IS ($1700. Image Stabilizer is a big plus)
If you like Canon lenses, always buy the L-series ones (professional lenses), not the cheaper ones.
B+W polarizer (dont buy the cheap ones. Somebody from Hong Kong is selling this filter at $30 discount. Reliable seller)
email me wmsports@yahoo.com if you need further info. Maybe we can travel and shoot pics together :)
