Keep in mind that, when you put a 1.4X teleconverter on an f/5.6 lens, the AF stops working.

Hmm, well don't worry - the 5DII has enough resolution for an 8Mp APS-C crop. Exactly the same pixel pitch as my old 20D!

So not the end of the world even with a 300mm lens.

However I would think a 400-500 lens would be much better. The Sigma 50-500 "Bigma" is a very good all rounder and used by many for wildlife - including NHL on this forum with excellent results.

Now comes with OIS.

Also of course the 100-400L is very respectable. Many award winning pics with 5DII and 100-400 L. Also there is supposed to be a 100-400L MkII coming this year, so might be worth waiting for that?

I always forget that I used to survive on 6mp then 8mp lol..... so spoilt in today's world!

I don't want to think what the 100-400 II might cost, but bet it will be a nice piece of glass.

I've been using my 5d-mkii with the 120-300 f/2.8 and matched 1.4x or 2x teleconverters

With the 1.4x it is a 420mm f/4 lens and with the 2x it is a 600mm f5.6 lens.
Yes it crops down nicely if needed.

I find I can even hand hold this combination, though I do prefer a tripod.

This image is from the 120-300 f/2.8 with the matched 2x teleconverter hand held.
(this is the old unstabilized version of this lens, have not found any incentive to spring for the much larger cash outlay of the newer stabilized version (yet!) )

The disadvantage of using a lens that's too short with a high resolution image sensor, and cropping later, is that you can't see the subject very well when composing. With a longer lens, the viewfinder gives you a better view, so you can time your shot until after the bird is done diggin' 'n' scratchin' (or the like.)

You might get the same shot, but you might have gotten a better shot that you missed because you couldn't see it.

Well, I usually use my 500mm and a 1.4x tc and that would be my recommendation but, a bit pricey these days $7K+. I have the older version and it is still light enough to use handheld for a short bits of time especially birds in flight. the new 500mm mk2 is quite a bit lighter. Just wish I could afford one. As a few mentioned the 100-400mm, which I also use, is a very nice lens for basic all around nature shooting and for birds in flight.
if you can get real close to small birds it's great. It also focuses real close, about 6.5 feet and with extension tubes it can be used as a nice close-up lens (not macro). From what I've read and seen in actual usage, the 400mm f/5.6 is supposed to be one of the best birds in flight lenses! And, it's extremely light and less expensive as the 100-400mm. Also, the sigma 120-300 f/2.8 looks like a really fine lens using 1.4x and 2x tc. I think NHL uses, or used, it and had some exceptional photos. All said, I guess budget is going to be the major factor. I would say get the best lens your budget will afford.

Actually considering getting rid of the 5D mk2, and spend the money on a 7D, get the 17-55 usm for walkabout and a 300mm L lens for birds. It pains me to lose the full frame, but I'm not a pro and can't justify 2 bodies and 6k lens's so versatility and cost must win out.

Il mull it over for the next few days. Thanks for the help folks.

A fast EF 300 L that will work with matched teleconverters is still going to nail you for 7$k

The 100-400 L zoom is a much less expensive option though it won't work with teleconverters on the 7d or 5dmkii.
Tested that option on both bodies with equally spectacularly unsuccessful results.
