Olympus is about to announce a new 35 mm f3.5 macro that goes to life size (1:1). For those who are not up to speed with Olympus digital that would be a 70 mm macro that shoots 2:1 in 35 mm equivlence. Thats a 34 degree AOV all the way to twice life size with no tubes or diopters attached. The 8mp E-500 entry SLR will also be coming with it.
