Check Shutter Count →The Sony FX6 (ILME-FX6) is a 2020 full-frame Cinema Line camera built around a 10.2 MP full-frame BSI Exmor R CMOS sensor — the same sensor technology as the A7S III, tuned for cinematic video with exceptional low-light performance (ISO 80–102,400, expandable to ISO 409,600). The FX6 features a 12G-SDI output, dual CFexpress Type A / SD card slots, and is designed as an affordable entry point into Sony's professional Cinema Line alongside the Venice and FX9.
Sony does not publish a mechanical shutter rating for Cinema Line cameras. The FX6 primarily operates with an electronic shutter for video recording; the mechanical shutter is used only when capturing still ARW images.
| Model | Release | Sensor | Est. Shutter Life | RAW Format |
|---|---|---|---|---|
| Sony FX6 | 2020 | 10.2 MP full-frame BSI | ~200,000 (est.) | ARW |
| Sony FX3 (compact sibling) | 2021 | 12.1 MP full-frame BSI | ~200,000 (est.) | ARW |
| Sony FX30 (APS-C) | 2022 | 26 MP APS-C BSI | ~200,000 (est.) | ARW |
| Sony A7S III (shared sensor class) | 2020 | 12.1 MP full-frame BSI | ~200,000 (est.) | ARW |
| Actuation Count | % of Est. Life | Assessment |
|---|---|---|
| 0 – 5,000 | 0 – 2.5 % | Very low — typical for video-first Cinema Line use |
| 5,000 – 40,000 | 2.5 – 20 % | Low mechanical use — camera used for both stills and video |
| 40,000 – 120,000 | 20 – 60 % | Moderate — more stills-oriented use pattern for a cinema camera |
| 120,000 – 180,000 | 60 – 90 % | High mechanical use — negotiate price |
| 180,000 + | 90 %+ | Near or past est. life — budget for shutter replacement |
Like all Sony Alpha and Cinema Line cameras, the FX6 stores the shutter count in ARW files under an encrypted MakerNote block at tag 0x9050. ShutterCount applies Sony's decryption algorithm (based on cubic residues modulo 249) and reads the count at the appropriate byte offset for the FX6's sensor/firmware combination.
All processing happens locally in your browser. The ARW file is never transmitted anywhere.
Yes. The FX6 includes a mechanical shutter used for still image capture. For all video recording, the FX6 uses an electronic shutter — mechanical shutter actuations only occur during still photo shooting.
It depends on whether the JPEG retains MakerNote data. Many post-processing tools and editors strip MakerNote from JPEGs. Drop a JPEG into shuttercount.app to attempt the read; for the most reliable result, always use an original ARW file directly from the camera.
A high shutter count on an FX6 indicates significant still photo use, which is unusual for a cinema camera. Investigate why: an FX6 with 100,000+ actuations may have been used as a photo/video hybrid by a photographer, which is not necessarily a negative, but does indicate higher mechanical shutter wear than a typical video-only FX6.
