Too good to resist searching for other shots of the kind by you. Congratulations!

Could you share something about your experience with the Sigma 300-800 in terms of image quality and manuverability?

The Sigmonster (mine is a 300-800 DG) is a very sharp lens - it's as sharp as my 500 f4 IS at 500 and 700 mm at equivalent AV and using the 20D's sensor. The only reason to stop down at these lengths is for more DOF. At 800 mm, it's decent wide open and returns to prime-like sharpness at f/8 to f/9.

PROs - reach, prime-like optics, and zooming flexibility

CONs - weight, size, no IS/OS, no focus limiter

The Sigmonster is my preferred long range lens, while the 500 f4 IS takes care of fliers and hand helds.

Here's a shootout between the two (1.82 MB file):
