The Olympus 40-150mm f/4-5.6 is a compact telephoto zoom covering an equivalent 80-300mm range on Micro Four Thirds. It is a capable and affordable telephoto option, useful for wildlife, sport and compressed perspective shots. Lightweight and compact, it pairs well with the E-M1 for a travel telephoto combination that fits easily in a small bag.

Again - really small and light - even does some macro.
