Be careful what you ask for

otherwise you MAY get it ......

Most if not all of Sigma's standard zooms aren't pretty on full frame unless Heavily stopped down, the edges on the likes of the 24-60, 24-70 and 28-70 EX DG Macros don't get reasonable until F8 or smaller is achieved and the typical Sigma sample variation omn these lenses means that you'll be trawling through crates of the things to find one which is any good full stop - the wider EX primes are just as bad or worse on FF (the 24 F1.8 EX needs F16 and the 14mm never makes it) .. Unless Sigma plan on using the EOS mount or even Nikon so you can use their glass, I really hope they avoid full frame like the plague ..

What they would benefit from is using a 1.5X crop as all their APS lenses handle that crop factor and it gives a bit more real estate.
