Hmmm.. what's new?... The [url="http://www.sigmaphoto.com/news/sigma-corporation-announces-five-new-lenses-three-new-cameras-at-pma-2010"]"FLD" glass[/url], which is actually not a fluorite glass bu claimed to have the same performance (with affordable price). Makes me think of the Sigma "APO"s...
At the same adress, the FLD glass is also clamied to have very high light transmission. I'm afraid, these 4 FLD glasses will not be utilized by the max aperture of the lens...

FLD was used in the 70-200 OS but it still perform worse than the Canon 70-200 IS II.
