Or the date of release. :)

Would be a cool lens though.

Based on what has been done on the Sigma 200-500/2.8 I wouldn't want to hazard a guess at heavy this thng would be.

Whoever thinks up these megazooms with constant fast aperture does not know what they're talking about or have too much faith in engineers.

Why stopping at 20-400/2.8? Why not 8-1200/1.4? I mean it's as logical and as possible as 20-400/2.8, so why not.:rolleyes:
