    The 24-70mm f/2.8L II is an extending zoom lens, similar to the MkI. Similar, but not the same - the 24-70 II extends as the focal length increases, just like the 24-105 (and most extending zooms). The original 24-70 has reverse zoom design, meaning that deep lens hood was just as effective at the long end as at the wide end. Not so for the MkII, where the hood will be effective primarily at the wide end.

    So, this means that the hood is attached to the red ring area in your picture, and doesn't move with the extending part of the lens? How silly is that!? This would seem to imply that you have the least amount of hood when you want the most, and vice versa. Is this true?

    The 24-70 extended opposite of normal, the longer the lens got the wider the angle so it actually worked with the long lens hood - really weird but the overall length of the lens & hood didn't change. All the other zooms I know of i.e. normal - when the lens is physically short, the angle is wide.

    The Sigma 8-16mm also does that, both front and back elements 'suck in' towards the centre of the lens at 16mm, at 8mm they both push outwards to opposite extremes. It kind of makes sense if you think of them as 'reverse telephotos' or whatever they are. Either way, the best part is that they work better with hoods, especially the Sigma because the hood is in-built and it has a very vulnerable bulbous glass element at the front (and if you're looking through the viewinder, you just don't notice which way the glass moves).
    An awful lot of electrons were terribly inconvenienced in the making of this post.
