Check Shutter Count →The Fujifilm GFX 100 (2019) was a landmark: the first mirrorless camera to combine a 102 MP medium-format BSI CMOS sensor, in-body image stabilization (IBIS), and 4K video recording in a single body. It launched the concept of a truly versatile medium-format system beyond the studio, aimed at commercial, fine-art, and documentary photographers.
The mechanical focal-plane shutter is rated at 150,000 actuations — lower than full-frame cameras because medium-format shutters are larger and more complex to manufacture at high cycle counts. Fujifilm does not publish an official rating; this figure is widely reported from Fujifilm service documentation. The GFX 100 also offers an electronic shutter (up to 1/16,000s) that adds zero mechanical wear.
| Model | Release | Sensor | Rated Shutter Life | RAW Format |
|---|---|---|---|---|
| Fujifilm GFX 100 | 2019 | 102 MP MF BSI | ~150,000 | RAF |
| Fujifilm GFX 100S (compact version) | 2021 | 102 MP MF BSI | ~150,000 | RAF |
| Fujifilm GFX 100S II (2nd gen) | 2024 | 102 MP MF BSI | ~150,000 | RAF |
| Fujifilm GFX 100 II (flagship successor) | 2023 | 102 MP MF BSI | ~150,000 | RAF |

| Image Count | % of Rated Life | Assessment |
|---|---|---|
| 0 – 7,500 | 0 – 5 % | Very low use — near new |
| 7,500 – 45,000 | 5 – 30 % | Low to moderate use |
| 45,000 – 105,000 | 30 – 70 % | Moderate to heavy use — within rated life |
| 105,000 – 135,000 | 70 – 90 % | Heavy use — negotiate price significantly |
| 135,000 + | 90 %+ | Near or past rated life — budget for shutter replacement |
Both share the same 102 MP sensor and ~150,000-actuation shutter rating, but differ in important ways for used buyers:
GFX 100 advantages: Integrated vertical battery grip for better portrait ergonomics and extended battery life, dual battery capacity (~800 shots vs. ~400 on the 100S), larger body for better stability with heavy GF lenses.
GFX 100S advantages: Significantly more compact and lighter (~900g vs. ~1,400g with grip), lower used prices, more recent manufacture so likely lower shutter counts available on the used market.
For studio and commercial use, the GFX 100 remains compelling at its used price. For travel and handheld use, the GFX 100S is generally the better choice.
Yes. The GFX 100 was the first GFX camera with in-body image stabilization, providing up to 5.5 stops of compensation. The IBIS uses the sensor-shift mechanism to stabilize, which is separate from the mechanical shutter and does not affect shutter wear.
The GFX 100 has two SD card slots (UHS-II compatible). Unlike the later GFX 100 II, it does not accept CFexpress cards. For the best continuous shooting performance with 102 MP RAF files, use UHS-II SD cards rated for at least V60 speed.
Yes. The GFX 100 uses the Fujifilm G mount and is compatible with all GF lenses. It is also compatible with G-mount tilt-shift lenses and available adapters for Hasselblad V, Mamiya 645, Phase One, and Leica S lenses via Fujifilm and third-party mount adapters.
