    • Excellent pocket camera

      on August 2, 2019

      Bought this to replace a Rx100 II, especially for the viewfinder. The viewfinder works great. This camera takes really great photos and is fantastic for bringing on vacations. Great if you are not a serious photographer and want better pictures than a smartphone.
