At the risk of going over a well worn path, I am posting regarding the Oly 9-18 vs Pany 7-14. I have read many posts here and elsewhere. I have a OM-D E-M5 and looking to buy a wide angle zoom for a trip to Sicily and Rome next month. I will be photographing sunsets, sunrises, and the icons of Rome at night. And because of this and the "purple" issue with the Pany 7-14, I am ready to purchase the Oly 9-18. The price of the lenses is not an issue. My problem is that I do like FOV's wider than the Oly lens gives. I have a Nikon D300 and a Tamron 10-24, a combo which have made almost 4000 images with. Of those half of the images would fall within the 7-8mm range on a micro 4/3, so I clearly tend to use the wider angles. However, I do not want to spend a lot of time dealing with purple blotches. Before I send off an order, I decided to reach out to the micro 4/3 group for any input.
