Drop an ORF file from your OM System OM-5 Mark II or use the camera menu method to get the exact shutter actuation count — file processing is entirely in your browser, never uploaded anywhere.
Check Shutter Count →The OM System OM-5 Mark II (2024) is the updated version of the compact, weather-sealed mid-range Micro Four Thirds mirrorless camera. Featuring a 20 MP BSI CMOS sensor, IP53 dust and splash proofing (operating down to −10 °C), up to 7.5-stop IBIS, and a compact body designed for outdoor and travel photography, it is a strong choice for buyers seeking a robust all-weather mirrorless at a mid-range price point.
| Model | Release | Sensor | Est. Shutter Life | RAW Format |
|---|---|---|---|---|
| OM System OM-5 Mark II | 2024 | 20 MP MFT BSI CMOS | ~150,000 | ORF |
| OM System OM-5 | 2022 | 20 MP MFT BSI CMOS | ~150,000 | ORF |
| OM System OM-1 Mark II | 2024 | 20 MP MFT stacked BSI CMOS | 400,000 | ORF |
The OM System OM-5 Mark II uses ORF (Olympus RAW File) format. Unlike Canon CR3 or Sony ARW files, ORF shutter count embedding is not confirmed for all firmware versions. Two methods are available:
| Actuation Count | % of Est. Life | Assessment |
|---|---|---|
| 0 – 10,000 | 0 – 7 % | Very low use — near new condition |
| 10,000 – 40,000 | 7 – 27 % | Low use — substantial life remaining |
| 40,000 – 80,000 | 27 – 53 % | Moderate use — normal for active outdoor use |
| 80,000 – 120,000 | 53 – 80 % | High use — inspect carefully; check seals and LCD |
| 120,000 + | 80 %+ | Near est. limit — factor in potential shutter service |
For a weather-sealed outdoor camera like the OM-5 Mark II, also inspect the weather seals around ports and the battery compartment, the LCD for scratches, and verify the tilt-and-swivel mechanism operates smoothly.
The OM-5 Mark II (2024) builds on the original OM-5 (2022) with these key improvements:
The sensor (20 MP MFT BSI CMOS), weather sealing (IP53), body dimensions, and shutter mechanism are essentially unchanged from the original OM-5.
The most reliable method is via Menu → Setup → shutter count display on the camera. You can also drop an ORF RAW file into shuttercount.app — the tool will attempt to extract the count from EXIF MakerNote data if embedded by your firmware.
OM System does not publish an official rating. The estimated lifespan is approximately 150,000 actuations.
No. The OM-5 Mark II supports a fully electronic shutter mode. Electronic shutter exposures do not actuate the mechanical curtain and do not increment the mechanical shutter count. The Handheld High-Res Shot mode (which composites multiple frames) uses the mechanical shutter for each sub-frame — be aware that this mode increments the count more rapidly.
