Going for 10 days to Cape Town next month. This is supposed to be a great town with plenty of highlights. We also plan to visit the coast lines (potentially whales) and the wine area (Stellenbosch). I have an EM5, and my current set of lenses consists of the Oly 9-18, Oly 14-150, Oly 45/1.8, and Pana 20/1.7 and 100-300. I must admit that I am more a zoom person then I prime guy. I don't want to take them all with me, so which ones do you recommend? And would buying the new Pana 12-35/2.8 be very beneficial for me during this trip, also considering the lenses I already have?
