The Camera Elo: The Camera Elo represents a comprehensive rating system for digital cameras based on a large number of pair-wise comparisons, as undertaken via the CAM-parator online tool. The Elo takes image quality, as well as body characteristics and camera features into account. Both current and discontinued models are assessed according to a consistent approach. The ratings are derived in a similar way as the Elo of chess players. In addition to more details on the methodology, the page also reports the ratings of the 30 top-ranked cameras.

Update of the CAM-parator App: The new Ricoh WG-60 waterproof compact camera has been added to the camera comparison tool. Hence, it is now possible to easily compare its relative size, sensor characteristics, and core features to other models. Just select your pair of comparators using the search boxes below and you will promptly see a corresponding side-by-side comparison.
