How to use the Camera Shutter Count Checker
- Take a fresh photo with the camera you want to check, or use the newest original file from its memory card.
- Drop the JPG or RAW file on the box, or click Choose files. Do not edit or export it first: that removes the maker notes.
- Read the shutter count. The badge tells you whether the number is an exact counter, a decoded value or only a Canon file number.
- Enter the rated shutter life from the camera's specifications to see how much of it has been used.
- Checking several bodies? Drop multiple files and click Download CSV to keep a record.
Where the shutter count is hidden
Every camera writes EXIF metadata into its photos: model, date, exposure and lens. Inside the EXIF block is a maker note, a private area each manufacturer formats in its own way. When a brand records the shutter counter at all, it lives there. This tool parses the TIFF structure of the file, finds the maker note and reads the brand-specific tag:
| Brand | Where the count is stored | Reliability |
|---|---|---|
| Nikon (DSLR, Z series) | Maker note tag 0x00A7 ShutterCount, a plain 32-bit number in every JPG and NEF | Exact |
| Pentax / Ricoh DSLR | Maker note tag 0x005D, scrambled with the photo's date and time tags | Decoded, very reliable on DSLRs |
| Sony Alpha | Encrypted maker note block 0x9050 (byte substitution cipher) | Model-dependent: compare two photos |
| Canon EOS | Not stored for most models; tag 0x0008 holds the file number | Approximate image count only |
| Fujifilm, Olympus / OM System, Panasonic, Leica | Not written to photo files | Check the camera menu or service software |
A quick sanity check for decoded values: take two photos a few frames apart. The second file should show a count that is higher by exactly the number of shots you took.
Buying a used camera: how to use the number
- Ask the seller for a fresh photo taken today, sent as the original file (by cloud link or email attachment, not through a chat app that recompresses images).
- Check the date taken in the details table. An old photo can hide hundreds of later shots.
- Compare with the rated life in the camera's specifications. A count under 20% of the rating is light use; above 80% leaves less headroom, but the price should reflect it.
- Remember mirrorless bodies may have been used with the electronic shutter, which usually does not add to the count, so also inspect the sensor, grip and buttons.
- Shutter replacement is a normal repair at an authorized service center; ask the seller for the receipt if it was done.
Frequently asked questions
What is a shutter count?
The shutter count, or number of actuations, is how many times the camera's mechanical shutter has opened and closed. Like the mileage of a car it is the best single indicator of how much a camera body has been used, which is why buyers of used cameras ask for it.
Which cameras are supported?
Nikon DSLRs and Z mirrorless cameras record the count in every photo, so they work best. Most Pentax and Ricoh DSLRs work too. Many Sony Alpha models store an encrypted counter that the tool deciphers, but the exact position varies by model. Canon, Fujifilm, Olympus/OM System and Panasonic cameras generally do not write the shutter count into photo files.
Why does it say no shutter count was found?
Usually the photo is not an original. Editing, exporting, sending through a messaging app or uploading to a website strips the maker notes where the counter lives. Copy a fresh JPG or RAW file directly from the memory card and try again. Some brands simply never store the count in files.
Is the Canon number the real shutter count?
No. For most Canon models the tool can only read the image file number, such as 100-4521. If file numbering was left on Continuous and never reset, it roughly matches the number of photos taken, but it ignores numbering resets and is capped at 9,999 per folder. The true count needs Canon service software.
How many actuations does a shutter last?
Manufacturers rate shutters for an average lifespan, often around 100,000 to 150,000 actuations for consumer bodies and 200,000 to 500,000 for professional ones. Check your model's specification and enter it as the rated life. A rating is an average, not a guarantee: many shutters last far longer and a few fail earlier.
Does the count include electronic shutter or video?
Generally no. The counter tracks mechanical shutter releases. Photos taken with a fully electronic shutter and video recording usually do not add to it, though behavior differs between models.
Is my photo uploaded?
No. The file is read with JavaScript on your own device. Only the metadata near the start of the file is parsed, and nothing is sent to a server.
