I'm off to Petra next week with my E-M1. I don't want to take more kit than necessary, so I'm trying to decide on the most suitable three (zoom) lenses. I've pretty much decided on the O12-40 and the P35-100. But I don't know enough about the geography of Petra to determine whether I'd be better with a wide-angle—P7-14—or telephoto P100-300. Does anyone who's been have an thoughts? Thanks.
