Photorumors list some new models... didn't take much to find the product pages on Sigma French site.

8-16mm F4,5-5,6 DC HSM
17-50mm F2,8 EX DC OS HSM
70-200mm F2,8 EX DG OS HSM
50-500mm F4,5-6,3 DG OS HSM
85mm F1,4 EX DG HSM
DP1x
DP2S

So... Sigma get really interesting again! Three lenses get the OS treatment, and a new 8-16 ultra wide zoom for crop sensors. 85/1.4 could be very interesting if they continue as they have done with other recent primes.

Hm. Interesting. Good thing I generally shoot sports with my 70-200.

The new one looks almost as though it got the Nikon 70-200 VR I annoexic treatment though. Especially the focus ring...

Looks like Sigma is also hopping on the stabilized fast mid-range zoom bandwagon as well.

Why did the 50-500 loose the EX? Then the only difference with the 150-500 would be the wide end :evil: Hope it is a typo, keep my fingers crossed.

I presume it's for the same reason the 150-500 also isn't an EX lens: no constant aperture.

The optics are still great, but Sigma is reserving the EX denominator for their fixed aperture lenses ;)

Historically they have had non-constant aperture EX lenses, and it does seem an inconsistency if the predecessor model was but the replacement isn't, assuming they're the same performance.

There's the big question - is the performance the same? If not, better or worse? The current version is 20 elements in 16 groups, and the OS version is shown as 22 elements in 16 groups. The increase is not unexpected due to the OS mechanism, but the arrangement is different internally regardless.

Also what makes a lens EX is the build quality of the lens body :-)

Don't forget that they've added two FLD elements, which should help with correcting chromatic abberations. One of the things that I notice when pixel peeping is that the Sigma 70-200mm exhibits some amount of blue fringing and blooming at high contrast areas. Perhaps this will fix that issue?

I'm looking forward to the 8-16mm, 17-50mm and new 70-200mm. When those are released, I'm going to get calls from divorce lawyers ...

pgtips, should we rename you Mr Sigma yet? If you're going to ditch ther other half, why not go all out and get the bargain 70-200 2.8L IS II? :D (edit: or have you switched to Pentax now?)

On the FLD elements, it remains to be seen what their performance is. If it really is as good as, for example, Canon's flourite elements, but at a lower cost, it could really shake things up.

Pretty much. 50D is not really used and is sitting in a drawer.

Was going to buy some Pentax DA* lenses, but now I think I'll wait a few more months to see how these Sigmas do.

A fish eye is just a wide angle lens that is not corrected for distortion. 8mm will be very wide. Look up samples of the Sigma 10-20 at 10mm, and imagine it even wider!

Isn't the Tokina 10-17 a near fish-eye wide angle? I heard it didn't cover the full 180 degrees
