We are making a trip to Alaska this summer. It will be a cruise followed by a land portion ending in Denali. This trip will include whale watching, site seeing tours and town scapes. I am trying to decide which lenses to take to minimize weight for a more pleasurable experience, but know this is the last time I will probably go to AK. I currently have the following Z lenses in my arsenal: 24-120 f/4, 100-400 f/4.5-5.6, 600 PF f/6.3, 50 MC f/2.8, and a 1.4 TC. I use these with my Z8. I am currently considering taking the 24-120 and the 100-400 with the 50 MC and the 1.4 TC, leaving the 600 PF behind. This gives me a lot of flexibility but leaves out the super telephoto, so taking pics of the Dahl Sheep will be a challenge! Thoughts? Do I need to add something to the set or leave something else behind. Adding the 600 to my backpack as is just won’t work unless I leave the 100-400 behind.
