Voila le test dont je parlais:
A review of the Sigma APO 150-500mm lens, comparison to Canon 100-400mm lens

J'ai apprécié la conclusion du comparatif de ce lien:

I have one word of advice for those of you who are considering purchasing this lens in a Canon mount -- pay the extra bucks and get the Canon 100-400. It is a much better lens.
