The 24mm f1.8 is is a total fake. It's an EVIL camera, for God's sake. As has already been pointed out, a 24mm f1.8 for a 35mm SLR (or an APS DSLR that shares a 35mm SLR's mount) is huge. It consists of a 50mm f1.8 design with a 2x wide converter, a two stage reverse Galilean telescope on the front. Like those "screw on" wide angle adapters, but permanent, and computed with the 50mm f1.8, so it doesn't add as many aberrations as a "one size fits all" design.

But that design does add some aberrations, compared to a real 24mm symmetrical (or at least much less retrofocus) lens for a camera that isn't contained by a mirror. http://forums.dpreview.com/forums/...
