I'm pretty sure I am exacerbating the problem by shooting HDR and resultant +2 photos. I've read elsewhere, and a long while ago, that lens flare is a real constraint. I'm guessing you ran out of space, sorry I didn't get a chance to look earlier!
To answer Larry, I will also consider that style of landscape, looking forward to the challenge. The wide side (let's say below 35mm) is an adjustment for me. I'm guessing you were actually pretty close to the mountains in the background?
