"... the RF-S 18-150, an excellent walking around lens."
I second this as the best basic choice but for wildlife it will be a little short so you will need a longer FL zoom for that depending on what wildlife you intend to shoot. Get the RF-S 18-150 first because one lens isn't usually a solution or even a possibility. I would sell the 35mil to help finance the more practical RF-S 18-150 and possible longer FL zoom.
