My first time in Alaska I was just in awe. I'm from Montana and Alaska is Montana on steroids X 20. My Sigma 150/600 lens got quite the work out. This was a little bee that was not much bigger than your little finger nail. I was sitting on a hill looking down at all the flowers and all the bees. So I thought I see if I can get a shot of one of them with a telephoto. So this is one of many. Alaska is insane and a great place for a long lens.
