Summary: For several years my Holy Trinity of lenses did not have overlapping focal lengths. I had a 7 to 14, 12 to 35, and a 35 to 100. Because there were no overlapping focal lengths this necessitated a lot of lens swaps in the field. My current set has an 8 to 18, 12 to 60, and 50 to 200 which require a lot fewer lens changes. This is good. In fact, it was one of the primary reasons I had for making the changes.
