Nick, Heinz and Tony, thank you very much for your responses.
For landscape work (meaning shooting vineyards and farmland), I really only plan on using the Canon 24-105L lens. The Canon 70-200L lens is only used when covering team sports, weddings, and some portrait jobs.
My last question

...If I just use the 24-105L lens, which NN5 setup would I need? The NN5, NN5-RD8, or the NN5-RD16.
At this point, I do not really understand the degree intervals..I probably will understand it more when I start doing panoramas with the NN5.
Thank you very much...
Ross
