Hi people I have the OMD with the two kit zoom lenses and 60mm f/2.8 for portraits and macro. I am going on a cruise to the South Pacific next week and probably going to get the 17mm f/1.8. I'm into candid shots as well as street/urban/cities/architecture and I think this will be a good choice. I'm assuming this lens will be the one that lives on my camera for many situations. I've browsed through the image thread extensively and I'm pretty impressed! Can I please have your thoughts on this?
