Really? Plastickly? For such a heavy lens? Granted, the exterior rings are all hard black plastic, but the barrel and all internals are metal. Maybe it's the glass that makes it heavy? I wonder if it's the inherent looseness in the focusing mechanism/design that contributes to the feeling you're experiencing? It's not the tightest moving set of controls I've ever experienced. keith > Fred
