Does anyone know why the front element on the DP1 is so big? It's huge considering that it is a 16mm f4 lens. My Olympus XA has a 35mm 2.8 lens that is half the width. You'd think that it could be recessed right into the body and be about the size of my fingernail, or a f2 version the size of my thumbnail.
It seems more like a SLR wide angle, I think they call it a reverse telephoto that is built like that to give the mirror room to swing.
I suppose they are trying to avoid extreme angles of the light hitting the sensor but I wish they would have gone with offset microlenses or some other solution.
