One of the real pleasures of the mountain is that you can worship the spectacular scenery that you can't find in everyday life. It is natural to want to leave beautiful pictures with a single-lens reflex camera or a mirrorless camera. So what kind of camera lens is suitable for mountain climbing? Looking back at the tens of thousands of photos taken during the climb, I came to the conclusion that choosing a single lens on a full-size machine would be a “1-24mm zoom lens” option. Here are some examples of what kind of photos you can take while climbing with this single lens. This time, the main focus is on the zoom range, so if you are using APS-C or Micro Four Thirds, please refer to this guide for selecting the angle of view.
