Cool website for those of you interested in camera lenses

This website has a really cool tool that lets you compare different lenses. I know it's for Tamron lenses, but it will still show you the difference between say a 17-35 mm lens and a 70-300 and a bunch of other lenses. It would be the same effect with a Canon or Nikon lens. You can also click on digital or 35mm to see how a digital camera will crop the photo because of the crop factor on digital cameras (I won't get too techinical here, but unless you have a super high end professional camera part of the image will be cropped out as compared to how it would look if you used the same lens on a 35 mm film camera) Focal Length Comparison Tool

It also has another tool that also lets you see the effect of changing the f-stop/aperture on the depth of field. (so you can get those pictures where the background is blurred).
