I am not the person you are asking the question to. However, based on your answer, I have a question for you.
Is it a deal breaker for you that the DUO does not have the telephoto lens that the Pro has?
I have had Pros for years now. I am a point and shoot guy. I rarely use the telephoto lens, though it's a nice option to have. As long as I can still take incredible photos of National Parks with the DUO, then I should be fine.
What is your take and are you planning to get the DUO?
