  Just wondering if anyone can advise on what filters to buy as I want to get into taking seascapes, rivers etc a bit more with the blur techniques.

  I am using a 5D & 40D with mainly the Canon EF Zoom lens – 24 mm – 105 mm lens

  Any help would be greatly appreciated.

  Thanks

  A polarising filter will be great to stop that glare from the water. Other than that, an ND grad filter will be useful to darken the sky while keeping the water clear.

  Have fun.

  You would need a ND filter to lengthen the shutter time to achieve
  blurred water without it being overexposed. Thats as opposed to a
  ND grad which is graduated from dark to light used for dealing with
  bright skies. ND’s can be bought in different strengths or try the new
  type that gives you all the different strengths in one filter and is used
  like a polariser by turning it to achieve different strengths.

  10 stop ND filter effectively, to do what you imply you want to, as you need something to get your exposure into 30 seconds + area. There are also variable ND filters that can stop up to about 8 stops of light or so, which you may want to look into also.

  EDIT: the above are straight ND filters. ND Grads will help you lower the brightness of the sky, and polariser as mentioned, to deal with reflections.
