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 long 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 21 Missions of California:

I used just one camera for the entire trip--the Nikon D800.
Given the number of architectural images that I captured, it's not surprising that the ultra-wide Nikon 14-24 was the workhorse once again. My Nikon 24-70 saw far more use than it usually does. The fisheye, micro and longer prime lenses served as specialty lenses for this particular journey.
One might question why I bothered to carry a lens that only contributes 2 to 3% of my total pictures for the trip. In this case, they were used to capture images that my other lenses aren't capable of capturing. Here are a few examples:
Sigma 15mm Fisheye
No other lens of mine is capable of including this entire circle within the frame.

I don't have any other lenses that can focus at such a close distance.

I don't have a lens that's any sharper than this one.

I brought this rather cumbersome lens along just in case I came across any California surfers. I'm glad I had it with me.
