Sigma 200-500mm f2.8 anyone?
 

A behemoth from Sigma announced today... gawd knows who'd buy it, a 400/2.8 is massive enough.

Your title says f4 which is why I didn't follow your comment above until I took the link and see it a constant f2.8.

Does look kind of chunky doesn't it - do you suppose its got IS :D

Oooops, now rectified.
Maybe aimed at sports photographers... can't see many dragging this around the countryside. Can't imagine it fitting on any gimbal heads either.

cheers,

who needs a gimbal head, surely you'd just handhold it! :D

Considering all the nice things I've said about my Sigma lenses do you think they'd let me try one out 'for a while' - providing they supply a caddy as well, of course!

I wonder how it compares to the 300-800 they make?

Heavier...much heavier.

I think you would need 3 shredded wheat before you went out with that for the day:)

Will not be at all surprise to see a shinny tiny battery operated golf car type automobile in shape of a tank only with lens instead of long gun be soon find its way into market with all these new heavvvvy huggggh lenses out there.

That's just silly!!
