Sigma fp L Shutter Count:
What You Need to Know

Sigma fp L — No Mechanical Shutter

Because neither the fp L nor the original fp has a mechanical shutter, the concept of "shutter count" — as a measure of mechanical wear — does not apply. Both cameras use the sensor's electronic readout to expose every frame. The sensor itself has no rated shot lifespan in the same way a mechanical shutter does.

Reading the Exposure Counter from a Sigma fp L DNG

Although the fp L has no mechanical shutter, it does record a total exposure counter in the EXIF data of its DNG files. ShutterCount can read this counter:

1. Take any photo with your Sigma fp L and locate the resulting .DNG file.
2. Open shuttercount.app in any modern browser.
3. Drag the DNG file onto the drop zone, or click to open a file picker.
4. The exposure counter appears. This is not a mechanical shutter count — it represents the total number of electronic exposures recorded.

What to Check When Buying a Used Sigma fp L

Without a mechanical shutter to assess, used fp L evaluation focuses on different factors:

• Sensor condition: Look for dead or stuck pixels, hot pixels at high ISO, and dust on the sensor. The 61 MP sensor resolves fine enough that even small sensor defects can become visible in high-resolution output.
• Lens mount contacts: The L-mount contact array can wear or corrode with frequent lens changes. Check all contacts are clean and making good electrical connection.
• USB-C port condition: The fp L is frequently used tethered or powered via USB. Check the USB-C port for play or contact damage.
• Body cosmetics: The magnesium body is durable but not weather sealed. Deep scratches near connectors or battery compartment can indicate rough handling.
• Battery and accessories: Verify battery holds charge. Original battery grip (HG-21) adds grip and a second battery — confirm it mates correctly.

Total exposure count (from DNG EXIF) can confirm the level of use as a stills camera, but even very high counts do not indicate impending failure since no mechanical wear occurs.

Sigma fp L vs Sigma fp — Shutter Count Comparison

Both the Sigma fp (24.6 MP, 2019) and the Sigma fp L (61 MP, 2021) use the same minimalist body design and identical electronic-only shutter system. The key difference is sensor resolution: the fp L uses a 61 MP BSI-CMOS sensor — the same resolution as the Sony A7R IV — offering substantially higher detail for landscape, studio, and architectural applications.

For shutter count purposes, the two cameras are identical: neither has a mechanical shutter, and neither has a rated shutter lifespan. The electronic exposure counter works the same way on both.

Sigma fp L Shutter Count — FAQ

Does the Sigma fp L have a shutter count?

No — not in the traditional sense. The fp L has no mechanical shutter. Its DNG files include an exposure counter (total electronic exposures), but this has no wear implications. There is no rated shutter lifespan.

Can I check the exposure count from a DNG file?

Yes. Drop a DNG from your fp L into shuttercount.app to see the exposure counter. Remember: this is not a mechanical shutter count and does not indicate wear.

Is there any risk of sensor wear on the fp L?

Electronic shutters can theoretically contribute to sensor aging at very high exposure counts over many years, but this is not a practical concern for normal camera use. The fp L is considered mechanically low-risk to buy used precisely because there is no shutter mechanism to fail.

Is ShutterCount free to use?

Yes, completely free. ShutterCount.app processes your files in the browser. No account, no upload, no limit on files.
