As you know the f/2.8 is great for action shots, lower lighting, and better bokeh. The f/2.8 is also heavier and a lot more expensive. The f/2.8 also lets in twice as much light as the f/4 does, therefore it focuses faster at all of the apertures, not just at f/2.8, since the AF speed is dependent on the light entering the camera. This feature will also give you a brighter view-finder and it will give you a little more leeway when it comes to adding extenders, because it will save you a full stop.<span style="font-size: x-small;"]<span style="font-size: 11.8056px;"]Furthermore, the MK II Version adds sharpness to the equation.
<span style="font-size: x-small;"]<span style="font-size: 11.8056px;"]I also have the 300mm f/2.8L IS, so I could show you a few of those on the 7D, but then I think you'll buy it. This is my longest lens, as of this typing (no expressed guarantees are intended)! I frequently use the 1.4X on it, with great results. The 300mm is really a speciality lens, the 70-200mm f/2.8L IS II with or without 1.4X extender has a lot more uses. The 300mm f/2.8 is a little heavy and conspicuous for walking around, not that any of the white lenses are stealth, but you could buy a black cover. If you get the 70-200mm II, then you could possibly add the 1.4x extender and do sniper zooming! You just put the 1.4x in your pocket and then lock and load. You may be able to sell your 300 f/4 too?
<span style="font-size: 11.8056px;"]As far as the 5D goes it's a great body; FF, low light, low noise, slower AF, landscapes, wider focal lengths, good for still shots. However, you sound more like a 7D guy to me! As you could see, the 7D does beautiful portraits too.
<span style="font-size: 11.8056px;"]Ok, so.., convince me why you need a 300mm f/2.8. []Go ahead.., it will be good practice, for when you tell your Wife.

]. I'll think about your post today and try to reply more detailed this evening. But you are certainly correct, I am more a 7D than a 5D guy because I do more tele action and macro shooting. Here's a collection of links that tell a story about my photographic skills (landscape is something that I want to learn better in future, but over all I am an action guy).
