Currently have an Olympus e620 and lenses that are fine for the photography I do. However, intend going on a wildlife trip soon and wanted to take videos as well as photos form some distance including treetops so had pretty well decided on a Canon 700d with 18-135. Then saw the Sony hx300 with 60x and panorama shots. Now not sure what is best choice?? I know they are different animals but would value your opinion.
