Check Shutter Count →The Sony RX100 III (DSC-RX100M3, 2014) was a pivotal model in the RX100 lineup, introducing two features that defined subsequent generations: a built-in pop-up OLED electronic viewfinder (0.39-inch, 1.44M dots) and a redesigned ZEISS Vario-Sonnar T* 24–70 mm f/1.8–2.8 lens. Compared to the RX100 II's 28–100 mm f/1.8–4.9, the III trades reach for a brighter, shorter zoom that excels in indoor and low-light photography. It also gained a built-in 3-stop ND filter for shooting wide open in bright conditions.
| Model | Release | Lens | EVF | Est. Shutter Life |
|---|---|---|---|---|
| Sony RX100 III | 2014 | 24–70 mm f/1.8–2.8 | Pop-up OLED | ~200,000 |
| Sony RX100 II | 2013 | 28–100 mm f/1.8–4.9 | None (hot shoe) | ~200,000 |
| Sony RX100 IV | 2015 | 24–70 mm f/1.8–2.8 | Pop-up OLED | ~200,000 |
| Sony RX100 V | 2016 | 24–70 mm f/1.8–2.8 | Pop-up OLED | ~200,000 |
The RX100 III does not have a silent electronic shutter mode — every still photo increments the mechanical counter, making the reported count a reliable reflection of actual use.
| Mechanical Count | % of Est. Life | Assessment |
|---|---|---|
| 0 – 8,000 | < 4 % | Very low use — near new |
| 8,000 – 50,000 | 4 – 25 % | Light to moderate use |
| 50,000 – 120,000 | 25 – 60 % | Moderate use — inspect carefully |
| 120,000 – 170,000 | 60 – 85 % | Heavy use — negotiate price |
| 170,000 + | 85 %+ | Near or past estimated life |
The RX100 III was released in 2014 — used bodies are now over a decade old. Beyond shutter count, inspect the pop-up EVF hinge (test deployment and retraction), the lens barrel extension (confirm smooth zoom), battery charge capacity, and the lens elements for dust or fungus.
The Sony RX100 III stores the mechanical shutter count encrypted in ARW MakerNote tag 0x9050 using Sony's proprietary cipher. ShutterCount applies the correct decryption for the RX100 III and reads the count from the appropriate byte offset. All processing happens locally in your browser — no file data is sent to any server.
As a used camera, yes — with caveats. The f/1.8–2.8 lens and pop-up EVF remain genuinely useful. The 20.1 MP sensor produces excellent stills. However, the RX100 III has no 4K video, no silent shutter, and no real-time subject tracking AF. If your priorities are stills quality and the EVF in a pocketable body, it's excellent value. For video or sports AF, look at the V, VI, or VII.
The RX100 II has a 28–100 mm f/1.8–4.9 lens with a wider zoom range but a narrower field of view at wide angle and a significantly slower aperture at telephoto. It lacks a built-in EVF (but has an accessory port for an add-on EVF) and lacks the ND filter. The III's built-in EVF, ND filter, and wider 24 mm angle of view are the meaningful upgrades.
Yes. The RX100 III has built-in Wi-Fi and NFC for transferring images to a smartphone via the Sony Imaging Edge Mobile app and for remote shooting. The Wi-Fi transfer speed is modest by current standards but fully functional.
Go to MENU → Camera Settings → ND Filter and set it to Auto or On. In Auto mode, the camera inserts the 3-stop ND filter automatically in bright conditions. You can also assign the ND filter toggle to a custom button for quick access in the field.
