What lenses should I buy for the om system om 5?

The OM-5 is a small hiking camera, so I'd keep the kit light. For one lens that covers most days, I'd start with the Olympus M.Zuiko 12-45mm f/4 PRO, which frames like 24-90mm on full frame.

After that, add one lens for what you're missing. For wide scenery, the Olympus M.Zuiko 7-14mm f/2.8 PRO is a serious tool, though a big one. For low light and a little background blur, the Olympus M.Zuiko 25mm f/1.8 is small and gives a 50mm-equivalent view. For wildlife or distant trail scenes, the OM System M.Zuiko 40-150mm f/4 PRO is the one I'd take.

Full details for every lens that fits the OM-5 are on its camera page.
