They don't really have a choice if they want to sell to the low end
market too....remember this is a US$100(!) lens
The same spec's in the past had a price-tag 10x higher!
(and the Nikon lenses are much more expensive too)
And once full-size chips come down in price (and up in quality,
including corners with wide-angles), this will prove a temporarily
solution anyway....
Let them have their cash-cow....;))
Don't think there will be room for 1.6x models in the future, once
that happens (not if but when). And certainly not for a permanent
range of 1.3x camera's.
