Canon Zoom Telephoto EF 70-200mm f/4.0L USM Autofocus Lens
Canon Zoom Telephoto EF 70-200mm f/2.8L USM Autofocus Lens
Zoom Telephoto EF 70-200mm f/2.8L IS Image Stabilizer USM Autofocus Lens
The first and second lens here posted is the only diference in the F, aperture?
The last one the diference is in the image stabilizer?
Is the first lens here posted a good choice to buy or just go for the image stabilizer?
The diference in prices are a little big between lens so what is a middle good lens? or is the image stabilizer so importante on this type of lens that is worth all the extra money?
Please clear my mind on this.
Edit: with a 2x exyender i get a 140-400mm lens right? is the extender worth the buy. does the image still come out sharp... what are de disadvantages of the extender and the advantages?
thanks.

I will ask my wife when she gets up.
She might be willing to shed some light on the matter.
She is CPC certified and sells these lenses for a living.

If you can live with f/4, the 70-200 f/4 is a great lens. It is optically at least the equal of it's faster cousins.
Between the two varieties of the f/2.8 version, there are a few differences:
- The IS version, has (of course) the benefit of IS. This can give you sharp results at shutter speeds up to three stops slower than what you could achieve hand-held. I can confirm that it really does! Of course, it won't stop subject motion... but it does have a "panning mode," where the IS is turned off in the horizontal axis. The IS on this lens is Canon's most recent version, and it rocks. Also...
- The IS version has a circular aperture diaphragm, which improves bokeh. There are a number of photogs that use this lens as a portrait lens, and does have beautiful renditon of OOF areas.
- The IS version may or may not have better weather sealing, I keep seeing conflicting information on this, and even Canon's site is not clear on the matter.
So in summation, if you can live without IS and can live with an f/4 max aperture, the f/4 version is a great choice, and a terrific value as well. With the high-ISO performance of the 20D, f/2.8 may be a little less important than it once was, but there is really still no substitute for speed. It's so nice to open up to f/2.8 and really throw that BG out of focus. And of course it is nice to avoid shooting at very high ISO, especialy for portraits since skin tones seem to suffer so much.

I have the 2.0x II extender, and use it occasionally with the 70-200 2.8 IS. It's a tenuous combination. You're starting off at f/5.6 (you lose two stops) which means AF still works, but barely. In order to get realy good sharpness, you need to stpo down at least one stop, so that puts you at f/8. Use this combination in very good light only.

When you want to use it with a 2x extender, go for the f/2.8 IS.
The 2x eats a lot of light, so get f2.8 to keep a useful aperture left.
And because the focal length becomes so long with 2x you want the IS to avoid camera shake blur. (To my understanding the IS keeps working with a proper Canon TC, correct me if I'm wrong.)
Kirbic was faster
