Drop a RAF file from your Fujifilm GFX 50S and get the exact mechanical shutter actuation count in seconds — processed entirely in your browser, never uploaded anywhere.
Check Shutter Count →The Fujifilm GFX 50S (2017) was the camera that launched Fujifilm's GFX medium format system and made large-sensor mirrorless accessible to a broader audience. Its 51.4 MP medium format BSI CMOS sensor (43.8 × 32.9 mm) delivers exceptional image quality, and the modular design with an interchangeable EVF was groundbreaking at its price point. The focal plane mechanical shutter is rated at 150,000 actuations — lower than APS-C flagships due to the larger shutter curtain dimensions required by the medium format sensor.
| Camera | Release | Sensor | Rated Shutter Life | RAF Tag |
|---|---|---|---|---|
| Fujifilm GFX 50S | 2017 | 51.4 MP medium format | 150,000 | 0x1438 |
| Fujifilm GFX 50S II | 2021 | 51.4 MP medium format | 150,000 | 0x1438 |
| Fujifilm GFX100S | 2021 | 102 MP medium format | 150,000 | 0x1438 |
| Fujifilm GFX100S II | 2024 | 102 MP medium format | 150,000 | 0x1438 |
The Fujifilm GFX 50S does not display the shutter count in its menus. The count is stored in the MakerNote section of every RAF RAW file the camera produces. ShutterCount reads it directly in your browser:
When evaluating a second-hand GFX 50S, the shutter count is especially important given the cost of medium format shutter replacements:
| Actuation Count | % of Rated Life | Assessment |
|---|---|---|
| 0 – 15,000 | 0 – 10 % | Very low use — near new |
| 15,000 – 45,000 | 10 – 30 % | Low use — plenty of life remaining |
| 45,000 – 90,000 | 30 – 60 % | Moderate use — normal for working photographers |
| 90,000 – 135,000 | 60 – 90 % | High use — negotiate price accordingly |
| 135,000 + | 90 %+ | Near or past rated life — factor in shutter replacement (~€300–500) |
GFX 50S bodies are often sold by professional photographers upgrading to the GFX100 or GFX50S II. Used counts in the 30,000–80,000 range are common and represent reasonable value if priced accordingly.
Fujifilm RAF files contain a proprietary MakerNote section within the EXIF data. ShutterCount reads tag 0x1438 (labelled ImageCount in ExifTool), which stores the cumulative shutter actuation count as a 4-byte integer.
This tag is consistent across the entire GFX lineup and most X-series cameras, making Fujifilm one of the more straightforward brands for in-file shutter count reading.
Fujifilm strips the MakerNote from in-camera JPEG exports on GFX bodies. The shutter count tag is only reliably present in .RAF RAW files. Always use the original RAF from the memory card.
Take a photo, locate the RAF file, and drop it into shuttercount.app. The count is read from MakerNote tag 0x1438 in your browser — no upload, no account required.
Fujifilm rates the GFX 50S shutter at 150,000 actuations. This is lower than Fujifilm's APS-C cameras because the medium format shutter curtain is physically larger and cycles more slowly.
The GFX 50S II (2021) is smaller, lighter, and adds IBIS (6.5 stops) — a major advantage for handheld medium format work. The shutter rating (150,000) and sensor resolution (51.4 MP) are identical. For used buyers, the GFX 50S offers the same image quality at a significantly lower price, but without IBIS.
The internal hardware counter can only be reset by Fujifilm service after a shutter replacement. The RAF ImageCount tag can reset under some circumstances (card format, firmware update) — always cross-reference with other evidence like cosmetic wear when evaluating a used body.
