The Olympus OM-D E-M10 Mark IV has an estimated shutter lifespan of around 100,000 actuations (no official rating published by Olympus). Like all Olympus cameras, ORF files do not store a confirmed shutter-count tag — check via the camera menu for the most reliable reading.
Check Shutter Count →The Olympus OM-D E-M10 Mark IV (2020) is the entry-level flagship of the OM-D line, designed for first-time mirrorless buyers and casual photographers upgrading from smartphones. It features a 20.3 MP Live MOS sensor, 5-axis IBIS (4.5 stops), a selfie-capable 180° tilting LCD, and 4K/30p video. Unlike the E-M5 and E-M1 series, it does not offer weather sealing. Olympus does not publish a rated shutter count for the E-M10 Mark IV; field experience suggests approximately 100,000 actuations.
The camera is designed for casual daily use rather than professional or semi-professional shooting, so the lower estimated shutter life is consistent with its intended audience.

exiftool -ShutterCount yourfile.ORF. ExifTool reads from Olympus MakerNote tags and may return a count on E-M10 Mark IV firmware, though results can vary by firmware version.The E-M10 Mark IV is an entry-level camera aimed at casual photographers. Many used examples have seen light use and will have low counts. The estimated 100,000-actuation lifespan means that modestly used examples can still offer significant remaining life.
| Actuation Count | % of Est. Life | Assessment |
|---|---|---|
| 0 – 5,000 | 0 – 5 % | Very low use — near new |
| 5,000 – 30,000 | 5 – 30 % | Low use |
| 30,000 – 65,000 | 30 – 65 % | Moderate use — normal for active shooters |
| 65,000 – 85,000 | 65 – 85 % | High use — negotiate price |
| 85,000 + | 85 %+ | Near or past estimated life |
Olympus does not publish an official shutter count rating for the E-M10 Mark IV. Based on its entry-level positioning and field reports, approximately 100,000 actuations is a reasonable estimate. Compare this to the E-M5 Mark III (~150,000) and E-M1 Mark III (200,000).
Yes. The E-M10 Mark IV offers excellent image quality from the 20 MP M4/3 sensor, effective IBIS (4.5 stops), a compact body, and an intuitive menu system — all in a lightweight form factor. Its lack of weather sealing and relatively modest shutter rating are acceptable trade-offs for a first mirrorless camera.
All Micro Four Thirds lenses (from Olympus, OM System, Panasonic, and third parties) are interchangeable. A lens used on the E-M10 Mark IV will work natively on the E-M5 and E-M1 series, and vice versa. This is one of the major advantages of the M4/3 standard.
Inspect: sensor cleanliness (shoot a plain surface at f/11), LCD condition (no dead pixels or scratches), IBIS function (verify with a slow-shutter test), card slot integrity, and overall button/dial feel. Since the camera has no weather sealing, check for any signs of moisture ingress around buttons and dials.
