I bought a Sigma 12-24, and even though it's slower it's somewhat better. I haven't used the 24-70, but the earlier 70-200 2.8 and 2.8 IS were not that great. The current IS v.II is quite good, but very heavy and large. Some primes, such as the new 100/2.8 IS are quite good, but many fast lenses are poor and some are almost pointless on digital. Until Canon came out with the 24TS-E II and the 17 TS-E I didn't think they could or were willing to make the effort to make a decent wideangle lens. Now those two are the only Canons under 35mm that I use. Until they make a serious effort to upgrade their poorer lenses neither Canon nor Nikon should contemplate higher density sensors. That was one of the reasons I took the Panasonics on the trip to Kenya as the pixel density combined with the lens quality gave me better results in a much smaller package than I could have assembled reasonably with Canon gear. Translated to full frame, the Panasonics have the equivalent of 64mp. Few Canon lenses are up to that, and similarly the Nikon lenses I've tried. Among the few full frame lenses that can truly be said to be adequate for the 16mp Panasonic sensors are newer Leica lenses; at least those 50mm and longer.
