ya he lenses do fit, however technically they arent compatible because the edge of the lens that hooks in to the frame doesnt latch onto the switchlock on the radarlocks, so there is a possibility that the lens may eject from the frame.
and for the nosepiece, do you mean the unobtanium part or the actual nosepiece that snaps on and off? cause if you mean the part that snaps on and off..no its not compatible. however the unobtanium pieces work for both.
