yes, just like nikon ff lens on aps c. same crop factor. i.e the 35 2.8 would be 52.5mm and 55mm would be 82.5mm
So if Sony does indeed come out with a 100ish-mm macro for FE, as rumors suggest, then it would be similar to shooting a Nikon 105mm on a D7000.
The NEX series would then have 30, 50 and 100mm macro options and the FE line would just have 100mm. (or the others in crop mode).
