I think, the mission is:
If they have to have heavy bags to stabilize tripods, you can use either sand or better looking lenses.
or:
Go an cover all FL with a f/1.4 version, make it big, black and heavy. "All FL ever made?" "Yes". (I'm already looking forward to 75/1.4, 90/1.4, 21/1.4, 45/1.4... and I'm sure, I missed half a dozen.
or:
Preparing the world for a 18-120/1.4 superzoom. All these primes are at least as heavy as that one would be. And no one would buy it, because in general Sigma doesn't take back all the already sold primes...
or:
Make a counterpart to all the featherlight sneakers and trainers this forum is exclusively flooded with. No other forum ever appears to be that attractive to this kind of brainless spammers. Are you guys supporting some poor Chinese who wanna make an extra buck?
More seriously: The 70-200 is about normal size, the 28 basically as well (for a f/1.4), the 56 about the size of the two Fujinons, just without the stupid retro aperture ring. The 10× zoom 60-600 is based on the design of the 4× zoom, will possibly weight a tad more than only the 2.86 kg, but hey, you get also a 60/4.5 at only 3 kg for it, so worth the effort (someone failed again in being "seriously"). The only super awkward and very weird surprise is this 40 mm no one ever asked for, but at least some commenter on Photorumors already is happy about and makes his personal winning team a 20 - 40 - 75 (why no 80??) - 105 (why no 120? or 160?)
