It may be interesting to know that apparently Canon has just started revamping it's 70-200 (f/4 non-IS/IS, f/2.8 non-IS/IS) lens line.
At least, that's what thought when reading this:

What I wonder about...in the article they write "The minimum focus distance has been reduced to 1.2m, with a corresponding increase in maximum magnification to 0.21x.".
I know my trusty 55-200mm has a magnification ratio of 0.29 and the 400mm 0.27...but what does it mean in practice ? Do you see real, major differences ? I've read the same about a lens I'm looking for myself, the Sony 28-75mm f/2.8 SAM - the magnification ratio being 'just 0.22'.
A (tele)zoomlens magnifies the things you see by the corresponding factor, but...still...don't get the whole picture about it.
Oh, and I do know a macro lens has a magnification ratio of 1.;)
