Paris - Arc de Triomphe

Paris is a great city. A starting point among the many Tourist Attractions is the triumphal arch, the l'Arc de Triomphe. Of course I had to go there on my first visit. And with my new Nikon D800e I had the right device to do it from above great panoramic shots close. But somehow I still can't get to grips with the settings of what is certainly a top-class camera. The images all look a little blurry or have strange distortions.

I guess I need to practice a little more...
