Still playing the sigmonster so I rushed after work to a local bird Sanctuary and shot a few with the Sigmonster on a monopod.
Real love the lens and I think that around 600mm it really shines though I got some nice ones wide open at 800mm
more to come as the weather gets better and my LLT improves!
The first two look like the lens was a tad too long for subject, or did you crop these? Douglas
haha
I was playing with the 300-800 and shooting at 800mm Wide open to check the IQ
They are not crops :-)
however in the future I promise to compose them a bit better :-P
