My father has a Sony 10MP digital SLR camera. We got it for him for his birthday and he loves it. Pardon my ignorance here, I am not versed in 'camera' language, but it came with a telephoto lens as well as the normal lens. Now he is asking for a telescopic lens for Christmas but when we went to the electronics store they didn't know what we were asking for. Unfortunately neither do we, and we want it to be a surprise so we don't want to ask dad. Can anyone help me out here? My mom can get the details on the lenses we already have if you need them. I think the telephoto is like a 70-300.
