Drop an SRW RAW file from your Samsung NX20 and get the exact shutter actuation count in seconds — processed entirely in your browser, never uploaded anywhere.
Check Shutter Count →The Samsung NX20 (2012) was Samsung's enthusiast APS-C mirrorless camera and a significant step forward from the original NX10. It was the first Samsung NX camera with a built-in electronic viewfinder — a 1.4M-dot OLED EVF — and added built-in GPS for geotagging and Wi-Fi for wireless image transfer. The NX20 also upgraded the sensor to 20.3 MP (from 14.6 MP on the NX10) and gained 1080p Full HD video recording. RAW files are stored in Samsung's SRW format.
Like all Samsung NX cameras, the NX20 is now exclusively on the used market following Samsung's 2016 exit from the consumer camera business. Its age (over a decade) makes a low shutter count particularly important when buying used.
| Model | Release | Sensor | EVF | GPS | Rated Shutter Life | RAW Format |
|---|---|---|---|---|---|---|
| Samsung NX20 | 2012 | 20.3 MP APS-C | Built-in OLED (1.4M) | Yes | ~100,000 | SRW |
| Samsung NX10 (predecessor) | 2010 | 14.6 MP APS-C | Optional external | No | ~100,000 | SRW |
| Samsung NX30 (successor) | 2014 | 20.3 MP APS-C | Built-in OLED pop-up | No | ~150,000 | SRW |
| Samsung NX1 (flagship) | 2014 | 28.2 MP APS-C BSI | Built-in OLED | No | ~150,000 | SRW |
The Samsung NX20's estimated shutter life is approximately 100,000 actuations. Given the camera's age and the discontinued NX system, shutter replacement is not straightforward — factor this into any purchase decision above 60,000 shots.
| Actuation Count | % of Rated Life | Assessment |
|---|---|---|
| 0 – 10,000 | 0 – 10 % | Very low use — near new |
| 10,000 – 30,000 | 10 – 30 % | Low use — good condition |
| 30,000 – 60,000 | 30 – 60 % | Moderate use — typical for a working camera |
| 60,000 – 85,000 | 60 – 85 % | High use — negotiate price; shutter service approaching |
| 85,000 + | 85 %+ | Near or past rated life — budget for shutter replacement |
The Samsung NX20 stores the shutter count in the Samsung MakerNote embedded in every SRW RAW file. ShutterCount reads this value locally in your browser without transmitting the file anywhere. The counter is a permanent hardware value that persists across battery changes and firmware updates — it cannot be reset without a physical shutter replacement.
The NX30 (2014) improves on the NX20 with a higher estimated shutter rating (~150,000 vs ~100,000), a better pop-up EVF design, and a flash sync port for studio strobes. The NX20 is typically cheaper, has a slightly smaller body profile, and includes built-in GPS that the NX30 omitted. For travel photography where geotagging matters, the NX20's GPS is a genuine advantage. For all other use cases, the NX30 is the better buy if condition and price are similar.
The NX20's built-in GPS receiver embeds latitude, longitude, and altitude in every JPEG and SRW file. No external GPS accessory is needed. The GPS receiver takes 30–60 seconds to acquire a fix from cold start; subsequent shots geotag instantly. The GPS is one of the NX20's most distinctive features — neither the NX30 nor the NX1 included built-in GPS.
No. The NX20 uses a conventional focal-plane mechanical shutter for all exposures. There is no full electronic shutter mode. Every shot increments the mechanical counter.

The estimated lifespan is approximately 100,000 actuations. Samsung did not officially publish this figure for the NX20.
At 40,000 actuations the NX20 has used 40% of its estimated 100,000-shot lifespan — moderate use. Given the discontinued NX system and the camera's age, prefer bodies below 30,000 when possible.
Resetting the counter requires physical shutter replacement. Always verify from an original SRW file — not a screenshot or JPEG — when buying a used body.
Samsung exited the consumer camera market in 2016 to focus on smartphone cameras. No new NX lenses or bodies have been produced since. The NX20 was one of Samsung's mid-range enthusiast releases during the platform's most active years (2012–2014).
