I'm not really much for wildlife photography though I have been attempting it a little more recently due to the proximity of a lake to my home. If I were to get truly serious about it I would start jonesing for a number of lenses that I cannot afford and subsequently drive my wife crazy. So... I dabble.
I found that exposure compensation was a big deal as I was shooting dark plumage and while trying to get enough light to have some shadow detail I had to make sure I didn't over expose the image and get something truly terrible looking.
I was especially pleased with this image, in the full resolution file, you can see he is looking RIGHT at me, perhaps wondering if I am a threat, or possibly if I taste good...
I was not pleased with the color rendition in this photo, I think it is simply a characteristic of this particular lens. Really need to place this lens next to my DA 55-300 @ 300mm and see how well they compare.
