This is our primary camera that we use on most of our photo shoots. The D810 is a high end camera that we originally purchased to photograph weddings and portraits. It works well for travel photography as well; it has a full frame sensor, a high megapixel count, which gives us plenty of room for cropping and zooming in post. It’s super sharp, highly adaptive, and the autofocus is quick and reliable. The only complaint we’ve ever heard anyone make about it is the weight, and Jake is so used to it by now that he feels naked without it.
I want to be clear though that for most people who want to take travel photos, the D810 is probably more than they need. If you just want photos for your website or to share with friends on social media, then a much less expensive camera is probably adequate. I still recommend a DSLR of some kind though, just because the flexibility of changing lenses gives you more opportunities to be creative and get the images you envision. We used to own a combination of prime lenses and telephoto lenses, but now we just carry the telephotos, not because we didn’t love the primes (they create slightly sharper images), but because we needed to limit the amount of gear we were carrying and wanted to make sure we always had the focal length we needed.
