Shutter Count Checker

Read the shutter actuation count from a photo, on the cameras that record one.

Shutter count is only reliably stored by some Nikon cameras, and only in an unencrypted form on many models. Canon never stores it in the file. Treat any number here as informational, not authoritative, for anything important like buying or selling a camera.

About this tool

A mechanical shutter is a moving part with a finite life, usually rated somewhere between 100,000 and 500,000 actuations depending on the body's class. The count is the closest thing a camera has to an odometer, which makes it the first thing worth checking when buying used.

The catch is that very few manufacturers write it into the image file. Nikon does, in an unencrypted maker note tag on most bodies, which is what this tool reads. Canon never does, storing the count only in internal memory that requires service software to query. Sony, Fujifilm, and Panasonic are inconsistent at best.

Treat any number here as one input rather than proof. It can only be as trustworthy as the file it came from, a seller can send you a photo from a different body entirely, and mirrorless cameras complicate matters further by using an electronic shutter for some or all frames, which may or may not be counted depending on the model.

Frequently asked questions

Which cameras does this work with?
Most Nikon DSLRs and mirrorless bodies, which store the count in a readable maker note tag. Some newer Nikon models encrypt it, in which case the tool will say so rather than guess.
Why doesn't it work for Canon?
Canon does not write the shutter count into image files at all. It is held in the camera's internal memory and can only be read with Canon's service tools or third-party software connected directly to the body over USB.
What is a high shutter count?
It depends on the class of camera. Entry-level bodies are typically rated around 100,000 actuations, enthusiast bodies 150,000 to 200,000, and professional bodies 400,000 or more. A count at half the rating is unremarkable on a well-kept camera, and shutters often outlive their rating considerably.
Does the count include electronic shutter frames?
That varies by model. Many mirrorless bodies increment the counter for mechanical actuations only, so a camera used mostly in silent mode can show a count well below the number of pictures actually taken.
Can a shutter count be reset or faked?
Resetting requires service-level access and is not something a typical seller can do, but the file you are given can trivially come from a different camera. For a purchase that matters, read the count from a photo you take yourself on the actual body.
