Three new Lenses Announced: 24-70 f/2.8, 24 f/2.8 and 28 f/2.8

Another perspective...

Looking forward to a new 24-70 2.8ii

Willing to pay extra for a zoom that is sealed and doesn't extend (worth at least $300 to me)
Willing to pay for 14% less weight (worth at least $300 to me)
Willing to pay for the additional IQ if it is as noticeable as the 70-200 2.8 v2 compared to v1 (worth $300-$500 to me)

Well, you're apparently looking forward to overpaying by $300, then.

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.
