I need greater telephoto capabilities on my g7. i understand that there are add on lenses such as macro and teleconverts for canon powershots right? but adapters are needed or something. I sort of researched online and discovered lots of confusing models of adapters to match many other confusing models of lenses. Of course i still don't have a clear idea. I would like to know basically what are the accessories needed (a must for the telephoto lenses to work,i.e things like adapters). protect filters i suppose are optional? Basic idea for me ? =)
