Jamie, YOU got yourself into the BBC calendar. The lens helped. That is wonderful light and composition. Eldar, that is a lovely shot of the historical Althing site, which has no buildings but is nevertheless a World Legal Heritage site.
I am a lucky owner of a used version of this lens, in pristine shape. I find that it takes some compositional work to come up with good photos, and that 28-35mm is a much easier FL to shoot. My landscape bag includes this lens, Sigma 35mm f/1.4 Art, 6D, CPL, Lee holder and GNDs, shutter release. Tripod comes in its own bag. ~5 kg of kit total. It still feels like a lot, when hiking up steep grades.
