Nearly every time I return from a trip, I'm asked about which lenses I used to capture the images. At the end of a trip, I like to look at the distribution of shots by lens. Here's how it looked for my most recent road trip to photograph the Three Southern Cities:
I used just one camera for the entire trip--the Nikon D800. Nearly 90% of my photographs were captured by one of Nikon's "Holy Trinity" of lenses--the 14-24, 24-70 and 70-200.
