Hi, I am a newbie m4/3 user. I had a Nikon D300 and D5000 with few zoom lenses but I got tired of lugging them so I was looking at Sony NEX5 and Oly E-P2 and I am now a proud owner of Oly E-P2 with a 14-42 "kit" lens. Sony NEX5 was really nice and felt really good in my hand but ultimately it's UI let me down. Oly's menu could have been designed better but it's way better than Sony NEX's. I am going to Disney World in September and am thinking about buying Oly 9-18mm or Oly 14-150mm lens. What would you recommend?
