Check Shutter Count →The Nikon Z6 II (2020) is the second generation of Nikon's all-around full-frame mirrorless camera. It uses a 24.5 MP BSI CMOS sensor with dual Expeed 6 processors (enabling faster burst speeds than the original Z6), a single XQD/CFexpress Type B card slot and a secondary SD slot, and 14fps mechanical burst. The mechanical shutter is rated at 200,000 actuations. It was succeeded in 2024 by the Z6 III, which doubled the shutter rating to 400,000.
| Model | Release | Sensor | Rated Shutter Life | Burst (mechanical) |
|---|---|---|---|---|
| Nikon Z6 II | 2020 | 24.5 MP BSI CMOS | 200,000 | 14 fps |
| Nikon Z6 III | 2024 | 24.5 MP partial-stack BSI | 400,000 | 20 fps |
| Nikon Zf | 2023 | 24.5 MP BSI CMOS (same sensor as Z6 II) | 200,000 | 14 fps |
| Shutter Count | % of Rated Life | Assessment |
|---|---|---|
| 0 – 10,000 | < 5 % | Lightly used |
| 10,000 – 60,000 | 5 – 30 % | Normal use for age |
| 60,000 – 120,000 | 30 – 60 % | Moderate to heavy — inspect carefully |
| 120,000 – 180,000 | 60 – 90 % | Heavy use — shutter replacement likely needed soon |
| 180,000 + | 90 %+ | Near or past rated life |
The Nikon Z6 II stores the mechanical shutter count in NEF MakerNote EXIF tag 0x00A7 (decimal 167). This is a standard, unencrypted Nikon MakerNote field used across all Nikon Z-series cameras and most Nikon DSLRs. ShutterCount reads this tag directly in your browser — no encryption processing needed, unlike Sony ARW files.
Shoot a mechanical NEF frame and drop it into shuttercount.app. The count is read from MakerNote tag 0x00A7 in your browser, instantly and privately.
Nikon rates the Z6 II at 200,000 actuations. The Z6 III that replaced it has twice the rated life at 400,000.
Both use the same 24.5 MP BSI sensor and have the same 200,000-actuation shutter rating. The Zf (2023) adds a retro aesthetic with physical dials and a smaller, lighter body, and benefits from firmware improvements over the Z6 II. For pure performance, the Z6 II and Zf are nearly equivalent; choose based on ergonomics and price.
Yes. The Z6 II supports electronic first curtain (EFCS) and electronic front curtain shutter modes. Electronic shutter frames do not increment the mechanical counter. Only full mechanical shutter actuations count toward the 200,000 rated life.
Only Nikon authorised service centres can reset the hardware counter. Always verify from an original NEF file, not a screenshot or JPEG.
