Though this lens does ad bulk to your e mount camera, it is well worth it as it outperforms the kit lens (most lenses) in every way possible. I tried the cheaper 55-210 lens In a shop and comes nowhere near this one. Bear in mind it is also much cheaper glass.
This 18-200mm lens paired with your e mount camera is still lighter and more compact next to bulkier dslr's. It shoots very nice pics and video and brings your nex/alpha e mount to a new level of quality pics and video!!
