Not well. The big zoom even compares poorly with nex lenses
You mean the VR 10-100mm f/4.5-5.6 PD-ZOOM ?
That appears to be geared towards shooting movies rather than stills (with PowerDrive zoom and ultra quiet focus motors), but it is 77×95mm. The roughly equivalent NEX is the SEL-18200, slightly larger at 75.5×99mm and doesn’t have in-lens VR.
So yeah, the biggest lens is about the same size but the NEX lens seems less featured (at first glance). Image quality remains to be seen.#
The standard 10-30mm kit lens looks about the right size to me, Any smaller than that would get fiddly.
