Both are compared (with some non-zooms), at:

The 12-24 appears to fit film SLRs, but the image will not
cover the whole 24x36mm frame - and nothing else will fit
the digital cameras and provide truly wide angle coverage
except for the 8 and 16mm fisheyes and 14-15mm (big...)
rectilinears... This new lens fills a REALLY big hole - I
get asked a LOT about wides for digital SLRs, and now there
is a real answer...! ;-)
