Tamron SP 150-600mm lens for Iceland

I just rented the Tamron SP 150-600mm lens to bring along on our vacation, and for the purpose of working on my project of bird photography in Iceland and Norway. We are staying in Vestmannaeyjabær for a couple of days and I am hoping there will still be some adult puffins left but either way I will be looking for pufflings! I cannot wait to see the many birds around both countries, and can’t wait to be able to shoot 600mm.
