One more thread exists about this lens, but I felt like it could be a good idea to start a thread purely dedicated to this upcoming Sigma tele lens, as I believe there will be a lot of talking about it and comparing it to other alternatives like Nikons own or sigmas non stabilized lenses so here it goes!
First the basic facts, compared to the earlier 70-200 HSM II:
Focal length: 70-200mm; 70-200mm
Max Aperture: f/2.8; f/2.8
Min Aperture: f/22; f/22
Closest focus dist: 140cm; 100cm
Aperture Blades: 9; 9
Mounts: Nikon, Sony, Pentax, Canon, Sigma; The same plus 4/3
Filter size: 77mm; 77mm
Dimensions: 86.4mm x 197.6mm; 86.5 x 184.4 mm
OS(Optical Stabilization): Yes; No
Sigma APO 70-200mm f/2.8 EX DG OS HSM:
The full release note can be found here: Sigma 70-200mm OS HSM
Here are some highlights for those who don't want to read it all:
- OS, Optical Stabilization built into the lens, works even with Pentax and Sony who already have it built in, as long as the in body OS is turned off. Seems a bit useless but remember that you can see the effect through the OVF.
- 9 aperture blades for great bokeh effects and nice out blown background.
- FLD glass, a new development, with quality equal to flourite glass, what that is I don't know, but probably good stuff.
- HSM in built focus motor for fast accurate AF, has existed in previous modes too.
- Extra adapter for the lens hood to extend the hood more and cover for cropped sensors.

Thats the starting facts, I can't provide a release date of in depth analysis of this lens, so I leave that to you guys!
Feel free to leave a comment or more and better information as it comes out!
