Just a quick shot from home, ive seen this effect many many times. Ita was kind of cool to replicated.

Parrot Jungle in Miami Florida. Picture Taken with Canon 40D and canon 70-200mm 2.8L IS USM Lens

Here is an examble of how sharp this lens is, this is my favorite lens it cost a lot but as you can see it's worth every penny. Note the picture is exported as a medium size jpeg so you may not see the real power of the lens if i had put the RAW file you will be surprise.
