Yes, versatility is nice, but I need to see technical excellence that makes this worth going for over the 400 2.8 or the 500 F4.

Interesting. My testing (and that of others here) suggest that low ISO, the cropped FF image has equivalent IQ (but fewer MP), and at high ISO, the cropped FF is clearly superior. I'm quite familiar with the 7D - and since getting the 1D X, my 7D has become quite familiar with the inside of a Storm case, and has forgotten what it's like to have a lens mounted.
Basically, at low ISO (less than ISO 800), there will be no meaningful IQ difference between the 7D and the cropped 5DIII
Just bought the new Sigma 85/1.4. It requires a +18 AFMA on my 5D III. I'm concerned that if I ever get a new camera body, and it front-focuses even a little bit more, that I won't be able to adjust it.
What do you think?
I will definitely bring a CP with me, as well as a ND.
A neutral density filter is what I forgot the last time I went to a national park... Yellowstone, in my case. NDs are a must for taking proper exposures of all the awesome waterfalls and rapids, if you want that soft, velvety water look. At glacier, you'll use it a LOT.
I will be going to Glacier National Park In late July. I am planning on taking quite a few pictures, as I love traveling to the National Parks.
First, should I look into purchasing (or perhaps renting) a specific wide angle? I hope I can upgrade to FF sometime, but this likely won't be until about 5 years down the road. The two options I was considering here are the 16-35 II and the 10-22.
Secondly, should I add an extender for wildlife?
Lastly, are there any locations that are a must? And is there any other specific gear that I "must" bring to have a successful trip?
Thanks and no thanks, Canon- I'm glad you're creating and improving products, but I'll stick with my 24-105L lens. I can live with 5% barrel distortion at the wide end in exchange for the increased telephoto reach. It's the best overall travel lens I've ever used.
