As mentioned earlier, lanscape format works well. In this case, the scene is from Dubronik and taken with a Leica 75mm SL lens which in my opinion is one of the best portrait or lenses on the planet. The rendring as you willsee inother photos from this lens is amazing and the contrast and sharpness is unmatched. Although I love shooting with an M, the SL lenses are ina league of their own.
Not a great photo to show as an example of an X-Pan or any other format, but I still find it interesting. Had the subject been framed a liuttle more to the right or left, I think this would have been a pretty good shot. However, as it is still somewhat interesting to view and contemplate.
