neuroanatomist said:Just crop, the IQ is the same. Why would anyone use a 400/2.8?
</sarcasm>
The supertele lenses are in a different IQ class. Cropping reduces IQ, a TC reduces IQ. There's no free lunch. The cropped 200mm or the TC might produce an acceptable image, but it would be better with the 400/2.8.
TrumpetPower! said:So, since it actually is a slightly different question, maybe, I'll give you a quick response.
There's a reason why all the Sports Illustrated (and other) photographers you see by the sidelines of NFL games all have two cameras with them that they're constantly switching back and forth between. And there's a reason that the one is a 400 f/2.8 and the other is a 70-200 f/2.8.
I'll also give you a bonus response.
If you don't know what that reason is, there are much better things for you to blow your dozen large on.

RGF said:Which super Tele would you recommend for wildlife, including birds. The downside of the 400 is it is short, the downside of the 600 is that it physically long and has 15' minimum focus distance. That leaves the 500 but with the new 200-400 (if it ever is a really product) is the overlap with the 500 too much? Does that speak to the 600 for car travel and the 200-400 to fly with?

It would depend on whether the birds are the primary purpose for the lens or just one of many purposes.
If all you're going to do is shoot birds, you want the longest and fastest lens you can get. Think of the Hubble, or maybe the Keck.
But the ideal birding lens is not going to be very useful for much else.
The 400 is the most versatile of the Great Whites. It's the fastest, for starters. And if you put on teleconverters you get the same reach and speed as the others. If a teleconverter is going to live on the lens, then the native equivalent will be better in every respect, but not by leaps and bounds; the 400 is still a superlative 560 f/4; it's just not quite as superlative as the 500 f/4. And the 400 is an awesome 800 f/5.6, even though the 800 f/5.6 is more awesome still.
So, that would be my recommendation. If you want an all-puropose Great White that'll be fantastic at a bit of this and a bit of that, the 400 is for you. If your needs are more specialized, get the one that best fits your specialty.
And, if you don't know what your needs are...get one of the Lesser Whites such as the 300 f/4 or 400 f/5.6 or 100-400. First, those are still wonderful lenses with many advantages over the Great Whites, especially including weight, size, and cost. You may well find that one of the Lesser Whites is your dream lens. And, if it turns out that you need more...by the time you outgrow the Lesser White, you'll know exactly which Great White is for you.

As usual, there is not a single answer because it all depends on what you are doing. An 800mm, for example, would be useless for trekking and hand held shots, but could be the best on a tripod in a hide. Read, for example, what the doyen of bird photography, Arthur Morris, says about the 300mm in http://www.birdsasart-blog.com/2012/03/07/gear-evaluation-the-canon-300mm-f2-8l-is-ii/dolina said:From most ideal to least. All these must have 1.4x & 2.0x TC
600mm IS II
800mm IS
500mm IS II
400mm 2.8 IS II
300 2.8 IS II
Wildlife + birds require focal length.

Based on TDP's ISO 12233 crops, the 400 II takes a reasonable IQ hit with the 2x. The 500 II + 1.4xIII is noticeably better.
I love my 600 II, and I can see adding a 300 II to my kit down the line, as well.
The 500 sounds like a good compromise in your situation...RGF said:TrumpetPower! said:RGF said:Which super Tele would you recommend for wildlife, including birds.

Thanks everyone for their great thoughts. I like shooting birds but also shoot cats (think Lion, Leopards, Cheetahs) as well as bears (Grizs).
Luckily I don't have all the money in my pocket yet - otherwise I buy one of each (if I had a really BIG pocket).
The biggest downside to the 600 is travelling. It will barely fit in my Gura Gear Kikobo and is pain to use in Safari vehicle in africa. 500 is the best compromise between weight, size and reach.
A buddy has the 400 which he loves and has encouarged me to get one - my expereince of the 2x on the 500 is mixed (at best), so I am bit cautious to go that routine.
