Are you say ef is not a sound decision? EF lens on a crop are very good - better than on a ff in most cases

I didn't put this as precise as I should - I was talking of the whole eos system with the ef mount (bodies, lenses, flashes etc etc and 3rd party equipment that only works along with this system). Basically the reason why there only is limited competition between manufacturers, unlike say the pc where you can plug in any gfx card you want.

And being a "system", I think is important to provide every customer in every stage of photographic experience with a longer-term, somewhat competitive, adequate "off the shelf" offer w/o forcing him/her to sell equipment (ef-s anyone?). And this is where Canon is temporarily lacking, it's not just Nikon trolls, but there is/will be a gap between consumer aps-c and 5d3+24-70ii that is too wide for some. The fact that many ef lenses shine on aps-c doesn't fix that.

Well there is the 5DII + 24-105 option plus of course the 5DIII + 24-105.

And the 7D which s a prosumer body at not much more than the 60D

Well, the 7d has dropped a lot since obviously the demand is low (I cannot find any other reason), when I got my 60d the 7d was much more expensive. And you're right about the 24-105, the key is really how Canon will handle the 5d2 - if you look at the 5d3 af, this is made to be used with a f2.8 lens, i.e. 24-70ii + some 70-200. But even if Canon couldn't care less about what people write in forums, I am sure they got the message by now.

What makes you say that?

From what I understand, the capability of the 5d3's af are depend heavily on the max. open aperture, or more and more af points loose part of the pattern detection - so if using say a 70-300L/4-5.6 you've got part of your af system disabled @300mm. It's ok to design it this way, and many promotion shots show the 5d3 with the 24-70ii or the 70-200/2.8.

On lesser bodies like the 60d, there are "sensitive" af points meaning that they control the focus more precisely, but the pattern (cross, double cross, ...) is independent meaning the manufacturer expects this af system to be used mainly with slower lenses.

Actually, all 41 of the 5D3's cross-type AF points are sensitive to f/4. With f/2.8 glass, you're still "only" getting 41 cross-type points. Only the five double-cross-type points requires f/2.8 glass.
