Default Sigma or Canon zoom lens for Wildlife?

I'm wanting one of these lenses to put on my Christmas list.

Sigma 50-500mm f/4.5-6.3 APO DG OS HSM SLD

Canon EF 100-400mm f4.5-5.6L IS USM

I would be using it to shoot wildlife, deer, elk, waterfowl ext. Amazon currently has the Canon for $100 less then the sigma. I like the Idea of the huge range on the sigma, but am I going to loose quality? Would love to hear some input from some people that have one of them.

More reach is always nice. But the L is very sharp, but for birds the extra 100mm is really helpful.

That's a new version of the Bigma (50-500) with OS. Just not sure how it performs yet. The old version was pretty good optically - but any time you re-design the optics of a lens it could go either way - it could be better, or they could have introduced issues. I'd scour the net for reviews of the new sigma. The canon is lighter so it's easier to hand hold so if you're hiking a lot the benefit goes to the canon. I use the 100-400L for my wildlife and it's a great lens. But if you're not hiking long distances and especially if you're using a tripod (or other support) then the sigma's extra reach is a huge bonus.

couple things. they are both good lenses and either would serve you well, from the reviews i read on the 50-500 os when i was looking at them its a good lens, pretty similar optics to the old bigma.

compared side to side, the 100-400 is sharper, especially wide open, actually it is sharper wide open at 400 than the sigma is at f8. also the sigma is not a true 500, its really more like 460-480ish.

Another question, I know you can get the 1.4 and the 2.0 extender for the canon. Is there also one for the sigma? Not sure I would need it, but having the option later would be nice.

I would be hiking with it, but I'm in good shape and don't mind a little extra weight. Although bigger lens would probably mean better chance of dropping it....I think I confuse myself more the more I think about it.

they will not allow the lenses to work, both the sigma and the canon are not big aperture lenses. So there will not be enough light to let the phase detect to work. The min aperture for the lens AF properly is F8 and at 6.3 with a TC it is way to dark.

I have both actually, and I did this test a while back on the same trip (just follow both links):
http://www.pbase.com/nhl/sigma_50_500&page=2

I've been traveling a lot lately so I can only bring one long lens. The Sigma is my lens choice because of its convenience, just check my postings in the wildlife section...

Also Tamron has a very nice lens in their 200-500

Thanks NHL, I saw lots of the pictures from Sigma I couldn't find any from the 100-400, but the Sigma photos look GREAT. I looked in to the Tamron lens as well I think that's a great option as well for $600 less.

which of the 3 would work the best for my kids outdoor Soccer / Football games? I think I'm leaning towards the Sigma right now just because I could just take one lens for most outdoor outings. But $600 less for the Tamron and taking 2 lenses is temping.....

I believe you'll find the Tamron's focus speed lacking for the sports. I would definitely go Sigma or Canon over Tamron if you want to shoot sports. Also realize - any of these lenses is only good in bright light. They won't be any good at night under lights.

I thought I would include some of the type of photo's I will be taking. These were all taken with the 18-135mm is and cropped.
