Excellent article and images. I went to Iceland last February and agree with many of the author's conclusions. It is a truly beautiful, authentic, country with an otherworldly landscape. I captured a different perspective of Iceland - see my gallery at www.georgepappas.net/iceland.
Remember to bring a large plastic bag to cover your camera backpack for condensation protection when you go indoors. Keep your backpack or other weight on the hook of your tripod - the wind comes out of nowhere and can be very forceful. My 5DII took a spill on the beach and the lagoon with my 90mm TSE - it still worked the rest of the trip but needed a visit to Canon repair when I returned. I will definitely go again...and again..
