Check Shutter Count →The Nikon D7100 (2013) was Nikon's flagship DX-format DSLR at launch — featuring a 24.1 MP APS-C CMOS sensor without an optical low-pass filter for maximum sharpness, a 51-point AF system with 15 cross-type sensors, weather-sealed magnesium-alloy body, and 6 fps continuous shooting. It was a favourite among wildlife, sports, and travel photographers seeking DX crop factor reach with enthusiast-grade build quality. The mechanical shutter is rated at 150,000 actuations.
| Model | Release | Sensor | Rated Shutter | Max Burst |
|---|---|---|---|---|
| Nikon D7100 | 2013 | 24.1 MP DX CMOS (no AA filter) | 150,000 | 6 fps |
| Nikon D7200 | 2015 | 24.2 MP DX CMOS | 150,000 | 6 fps |
| Nikon D7500 | 2017 | 20.9 MP DX CMOS | 150,000 | 8 fps |
The D7100 uses a conventional mechanical focal-plane shutter for every shot — making the shutter count a direct and complete record of total usage.
| Shutter Count | % of Rated Life | Assessment |
|---|---|---|
| 0 – 15,000 | < 10 % | Lightly used |
| 15,000 – 60,000 | 10 – 40 % | Moderate use |
| 60,000 – 100,000 | 40 – 67 % | Heavy use — inspect carefully |
| 100,000 – 135,000 | 67 – 90 % | Very heavy — budget for shutter replacement |
| 135,000 + | 90 %+ | Near or past rated life — significant risk |
The Nikon D7100 stores the shutter count in NEF MakerNote EXIF tag 0x00A7 (decimal 167) — the same standard Nikon tag used by the D7200, D7500, all Z-series bodies, and the full D-series DSLR range. ShutterCount reads this tag directly from the NEF file in your browser. No encryption processing is required.
Shoot a NEF frame and drop it into shuttercount.app. The count is read from tag 0x00A7 in your browser, instantly and privately.
Nikon rates the D7100 at 150,000 actuations. This is the same rating as the D7200 and D7500 that followed it.
The D7200 improves on the D7100 with better high-ISO performance, built-in Wi-Fi and NFC, a much larger burst buffer (18 RAW vs 6 RAW), and improved AF tracking algorithms. Both share the same 150,000-actuation shutter rating and similar DX sensor resolution.
Only Nikon authorised service centres can reset the hardware counter. Always verify from an original NEF file.
