I am really torn over what UWA to purchase for my OMD. I really like the images from the Panasonic 7-14mm though the lens flare issue is a huge turn off. I am traveling soon and know I will be disappointed if it turns up in a bunch of my images. Therefore I am thinking about the Oly 9-18 even though it isn't quite as sharp or wide. Plus if I save the money by going to the Oly 9-18 I might try and squeeze the 12mm into my budget to take wide angle shots while walking around at night or indoors. So have it at with the comments, hopefully you guys can share some good personal experiences with both lenses that can help me make my decision!
