So I after researching primes vs. zooms on Photo.net, I wanted to open up a discussion and see if anybody has any advice on using primes as opposed to a zoom when traveling. I have owned a dslr for a few years now and am finally getting a feel for and more experience with traveling and lens choice. Before I abandon the zoom I was hoping to see other's experiences with using primes, i.e. limitations, benefits, changing lenses, etc. while traveling. Do you miss zooms? Are primes too limiting? Do you put one lens on the camera for the day, or have several on hand to swap out. My current set up is a Nikon D80, Tamron 17-50mm 2.8, Sigma 70-200mm 2.8, Nikon 50mm 1.8, and the Nikon kit 18-135mm which doesn't see much use anymore. I have been brining the Tamron and Sigma on trips lately. I hate the Tamron, but love the Sigma. Also, I may upgrade at some point to the FX D700 so primes might be a natural move. My idea is to replace the Tamron with two primes to lighten my load, not look too conspicuous, and increase speed (the Tamron takes forever to focus). Looking at photos I have taken in the past I find that I have a tendency to either go fairly wide with the zoom, or use the full 50mm zoom. Occasionally I find photos that I have taken that are at about 35mm, especially of friends. I also will break out the heavy Sigma and use it as a walk around lens for people/action, especially for subjects I can not get too close to. I really like the 2.8 of the Tamron for low light, and it served me well recently when doing some caving. A 18-200 would have not performed very well in that situation. I found that there are two main ways of traveling. 1) Traveling quickly on tours, busses, observing quickly changing action. A zoom would seem to be more ideal so as not to miss anything. Could primes work here? 2) Traveling and spending time in one place. Primes seem like they would work well since photos can be better composed due to time not being a factor. I often revisit particular places multiple times in a city for example as light changes and I think of new ways to compose shots. I'm still learning so the more info the better. Thanks!
