I saw your post on the discussion about the 300 vs the 60-250. (I have both lenses too and I would definitely keep both) Nice pictures of Alaska. Nice shot of bubble net feeding! I was on the same (or similar) inside passage trip a few years ago. I had my Pentax SF1N with me and got some nice shots but my shot of bubble net feeding was just too far away.
How was the weather for you on your trip? The reason I went back to Pentax for digital was specifically because of the weather resistant system because during my trip to Alaska it rained a steady drizzle 8 out of 11 days.
