Camera lenses - Canon 100-400 vs Sigma 150-500

[John Harris <>]

 Hi All,
I am just after a comparison between the above two lenses for bird and
nature photos in general. I want to buy one of the other, but would like
some first-hand accounts from any users before deciding to spend my money.

Hope some of you can help!
