I have an Olympus E-Pl6 with several lenses including fast primes, but want to travel as light as possible. So I can take the Olympus with my 12-32mm lumix lens which is pretty slow, or take my RX100 Mk1. The Sony has a faster lens at the wide end, but gets slower as you zoom in. Olympus should be able to handle high ISO pretty well. Which would you choose?
