I apologize if this has been covered, but I've been looking and can't find it. Are there any precise release dates for specific lenses? I'm curious to see the 25mm f/2.8 as a landscape lens.

The new 50D has gapless microlenses; it is the new 5D2 that does not, apparently because of issues relating to orienting the edges of a full-frame sensor to reduce light falloff. I believe Canon hopes eventually to make all of their full-frame sensors gapless as well.
I hope that works out, because, depending on the angle of incidence, the 5D has about 60% more vignetting than film for the same lens. (In this case, I believe that the ZF35 was used for testing.)

Ok! I knew the 5D2 did not get the gapless microlenses but did not know the reason behind that choice (I was actually just suspecting they did not want to put a much better sensor in the 5D2 than in the 1Ds3). I guess the gapless microlenses will need to happen in the next 1Ds version, if they want to increase the resolution again (well, in that case, not only the microlenses will be useful, but the lenses may also need some serious work too ).
