Very inquisitive birds as you may already know. This one watched me intently for what must have been 10 minutes. Can't fault the lens again either. Some must be thinking that I applied a lot of sharpening to these image, which is not the case. All I do is a little sharpening to the image after downsizing for the web, which is normal. I have however processed the raw file more aggresively in LR4. The files do require a little more work.
