Mark,
I see, so it is true that microadjustment works "per lens".

So, would you recommend a camera with AF microadjust over one without? Meaning: obviously with is better than without, but how likely do you think it is that one ends up with a lens requiring camera AF microadjustment?

Honestly, I am not planning to change camera body soon. I'd rather get a good one and keep it for years, inviesting instead in lenses. So, probably a 7D is worth the extra 200 Euros over the 60D. I'd consider a 50D as well, but I don't mind the HD video capability of the 7D.
