Is it available for pre-order from B&H, yet?

I don't have the time, but I am wondering about using a 16-35mm lens to photograph wildlife. Maybe in a Zoo. The 200-400 seems more like it.
It's beautiful, can't wait to get my hands on the legendary unicorn.

I'm surprised no-one has mentioned the 400 DO IS II, you can be sure that's going to be the premium wildlife lens for many, many people.
I'm guessing he makes use of the zoom and the built in tc. He's got a 200-560mm lens in one package. When that lens came out some guy was gushing about how great it is to be able to switch things up so quickly, claimed it was better than having a set of primes (and yeah, 200, 300, 400 + tc is a lot carry around).
That said, I agree with you on the 400mm DO, I have the mark I version and while it is a little less contrasty than some lenses, it's a great lens, I love it. So darn light for what it is - it's the size and weight of my 200mm f2. I can literally hand hold it with one hand (why I would want to I can't say but it's possible).
I'll be taking a hard look at the mark II, if it is significantly better I'll make the jump, that's a great lens. I'd love a 500mm f4 DO.
I am pretty familiar with black bears. Not so much grizzles, and their behavior is quite different.
#1 rule of black bears is they feel the same way about you as you do about them. if you come around a corner and BOOM you are within swatting distance of a bear and he is suprised, you might be in trouble. thats the idea of bear bells, to give some advance warning. a dog or walking companions or singing also works.
When I see a bear, I stop, check for cubs, stay in plain view, and slowly get closer until it notices me. then i stop, take pictures and wait for it to either back off or stand its ground. keep eye contact, move slowly and deliberately. i have never had a bear do anything other than evaluate the situation and either tolerate me or leave.
Worst comes to worse and you get in a bad situation, prevailing wisdom is first back away slowly maintaining eye contact, and if you get charged (they paw the ground and bluff a few times first), either play dead or fight back while yelling, depending on how commited you think the bear is. I know of several people who have been charged and their yelling and stone throwing and stick swinging made the bear change its mind. Once the bear makes contact, play dead, they arent hunting you for food, they are trying to win a fight, so make them think they won. Never EVER EVER climb a tree or try and run away, bears legs are twice as long as they look, and they dont slow down AT ALL when they move from flat ground to straight up a tree.
I can't watch the video right now, but is it poasible when referring to the 50L II they might mean the current 50mm f/1.2L? Because technically the 50L f/1.0 was the first 50L.
I think I'll grab the 135 without IS once the new one is out...
