Best travel lens for the om system om 3?

For travel on the OM-3, I'd start with the OM System M.Zuiko 12-100mm f/4 IS PRO. It covers about 24-200mm in full-frame terms, so one lens handles most of a trip, and its stabilisation helps in dim churches and markets.

If you want something smaller, the OM System M.Zuiko 12-40mm f/2.8 PRO II is a bright, compact standard zoom, about 24-80mm equivalent. For evenings and food, pair either zoom with the Olympus M.Zuiko 25mm f/1.8, which frames like 50mm.

That matches the classic travel kit: one zoom plus one small fast prime. Check the travel guide for what else to weigh up.
