I am planning a trip to Alaska this September. I currently own a 7d which will be great for most of what I do. I am thinking of renting a backup camera just in case. I would like to take the 5d II. Would there be a great deal to learn with a 5d II or would it be a fairly easy transition between the two bodies? I would like to use the 5d II for landscape shots and the 7d for wildlife. I have a 17-40 I could use on the 5d. Thanks in advance for your help.
