A 100% crop from my Sigma 80-400

[alan sh]

Hand held, 400mm zoom at 1/400th and F5.6. Taken at 800ISO (light was low) and the peg was about 20 feet away.

I like the fact you can see the spiders web....

Impressive.

I'd really like to see a well done comparison with this lens and the EF100-400 IS.
Except for the reported slowish focus the sigma is a great lens?
No one seems to want to buy them-on oz ebay they are being offered for silly low prices
