I only managed to really try the Nikon one but I do not see why there should be any difference with the Canon version.
Why don't you visit and give it a go?
The D800 shot seems over-sharpened/over-processed to me to an extent where I would be ashamed of publishing it. I prefer your image with the tammy.
Just talked to a Sigma rep today at a demo day and the other version of the 150-600 (not the sport) is due to ship at least in limited quantities the first of February. He said they intend to ship both mounts not one and then the other.

So has anyone, anywhere seen actual photos with this lens that make them think it is worth the extra money as compared to the Tamron? I know that I have read that it is sharper and seen some charts, but what about the pics? Any good direct comparisons from users who have both?
had a play with one today at a large photo shop based show in north wales today ,and having used the tamron i can only say this lens leaves it standing in the dust ,i used it in really poor light in a narrow back alley type street .and even got a fair amount of lock on's of flying seagulls that appeared and disappeared as they flew overhead .done a mini review on flickr for now link here
the proof is in the pudding 1/200th sec hand held with nearly 3 k.g of lens that around 6lbs in weight to the yanks
