My 1st attempt using the 50-500 Sigma Bigma, im not sure yet if the lens is a keeper. I will have to give it the "zoo test" first.....

I don't know Troy :scratch
could be the heat here or my Monitor but it looks tad soft in the reds :dunno
I know I've seen sharper stuff from you but don't know what lens you were using then??

I have had that beast and it was shaper than that.
Was you hand holding or on a tripod.
What focal range were you at?
500mm was a tad soft and I would bring it back a notch.
