I currently have a Fuji X100S which is a great camera which I shall keep. However, I want more flexibility for my favourite subjects - landscapes and building interiors (particularly old churches). I think I need a wider lens, perhaps a wider zoom lens. I'm tempted by the Olympus 9-18 mm zoom which is both compact and (relatively) affordable. The next choice is the camera on which to mount the lens. Two seem sensible - Olympus OM-D E-M10 or Panasonic GX7. I think both would do a fine job, but should the 9-18 mm lens point me to one over the other? Thanks for any suggestions relating to the lens choice or the camera choice.
