EM-5 + 9-18 for Real Estate photos...Love it!

That's funny. I was thinking about buying the Panasonic 7-14 to have as a backup in case my 9-18 fails or gets damaged during a shoot. I think it's a good idea to always have a backup of every piece of equipment on hand when doing paid work. I've seen examples of the purple blobs to which you are referring but I figured I could work around that. For now, I've got the Oly 11-22 Four Thirds lens with adapter as my backup lens. Maybe I'll wait on the 7-14.
