I really like wide, and for shooting in european churches, it's useful and can help you avoid making panoramas. I first tried this lens (used) when I had my E-M5, but the purple flare issue led me to sell it almost straight away. I shot for a long time with the 9-18, but the funny little lock thing drove me crazy. Now I've just bought a 7-14 again, and mounted on the GX7 - hey! No flares. Yet. Hope it stays that way. Should be a good travel combination with the 14-140 II.
