I toatlly agree with Alex on both lens opinions.


I have both a 70-200 f/4L and a 17-40 f/4L and find them a perfect match outside. I also disagree with MOF_Sydney regarding the 70-200 for portraits. I absolutley love my 70-200 for portraits and the bokeh at 200mm is pretty much as creamy as it gets.


The 17-40 is great for landscape photography. I also use it for a walk-about lens, decent for a quick portrait at 40mm, great indoors if light is good (but works great with a 580 flash).


I bought the f/4 set at the time because of money, but if you can afford to buy a wider aperture that would be ideal.


Gregg: those are great shots! Thanks for posting
