I normally don't write about products prior to release, however I've gotten enough requests for information about filters for the 14-24mm that I'd be remiss to point out that Lee has recently updated their page on their upcoming filter system. They also sent an email out to those that had previously inquired about the system that had a few additional points in it: they aren't currently planning on producing a polarizer for the filter holder, the 150mm filters will be available in the US in June or July (they're apparently available in the UK at the moment), plus the system will be sold with a filter holder, a collar for the 14-24mm, and a hard edge 0.6ND graduated filter.
