The only lens I can think of is the Sony α DT 18-250mm f/3.5-6.3. There is nothing similar in the Emount that I know of.
The Sony A mount DT 18-250mm f/3.5-6.3 is designed for the APS-c sensors, and would be compatible with the A630 and be equivalent to 27-375mm f/3.5-6.3. You would need an adapter like the LA-EA3 or 4 but would not have image stabilization (I'm almost sure). Tamron may have a lens in that range and Sigma are introducing one, an HSM, in August.
