The tour of these islands takes you past the "Candelabre", which is an ancient glyphy etched in some fashion into the side of a hill. It was hard to see, possibly due to weather conditions. It was raining; or more precisely a very light drizzle. Any precipitation in this area is quite rare. I guess we're just lucky.
The boat ride out to the islands takes about 1/2 hour. The boat circles the islands for about an hour then returns.
The main attraction to these islands are the birds, penguins and sea lions. I got tagged once (i.e., with bird droppings); others were it several times. Wear a hat.
My only "long" autofocs lens is my 14-45mm (28-90 equivalent). I took that lens plus my 400mm, 200mm, and 135mm. I shot most with my 200mm lens and just a few with my 14-45. The 45mm was too short. While the length of the 200mm (400 equiv) was ok, it's manual focus, which is hard to do on a rocking boat. I took most of my shots with center-point metering. An area metering scheme would have been better to reduce the number of blown out areas. To compensate for the lack of autofocus I shut down my aperture to around f8 or so. Given the subject distance that gave me a little tolerance along with a reasonable shutter speed. If I'm going to do this type of shooting more often, I need auto focus. I'm not sure I'm ready to commit to that at this point.
