ShutterCount is certified to work with 104 Canon EOS (including recent ones), 67 Nikon and 29 Pentax camera models. New to ShutterCount? Use the Wizard! 200 cameras, unlimited readings. Trusted by 200,000+ customers from 130+ countries, this is the gold standard in shutter count reading software. The count is read directly from USB or Wi-Fi connected Canon EOS DSLRs and select mirrorless models, as well as from image files for Nikon and Pentax cameras. And you can save a trip to a service center by doing the reading for yourself. ShutterCount displays the number of shutter actuations (the shutter count) of your Canon EOS, Nikon or Pentax digital camera, so you can easily check whether a newly purchased camera is really new, or check how heavily used a pre-owned item is.
