I recently bought an OMD with the 12-50 for my first M43 camera. I am traveling to Europe in a few weeks and have been adding lenses to my kit. So far I purchased the 20/1.7 and the 45/1.8. Now I am debating getting something wide and/or something long. On the wide side I am not into the fish eye look so I am thinking maybe the 9-18 and I have no clue on the telephoto side, maybe the Panasonic 100-300? I came from shooting a canon rebel where I had a 10-24mm for wide and a zoom that went up to 270mm so for touring Europe I want to make sure I have a good range covered. Thoughts/recommendations/rationale for adding these lenses? Thanks!
