Check Shutter Count →The Nikon D4S (2014) is a mid-cycle refresh of the D4 that ruled the press and sports world for a full Olympic cycle. It keeps the 16.2 MP FX sensor and 51-point Multi-CAM 3500FX AF module but adds the new EXPEED 4 processor, Group Area AF, an expanded native ISO range up to ISO 25,600 (usable to 409,600 expanded), 11 fps continuous shooting with full AF/AE, faster buffer clearing and sharper high-ISO noise reduction. The mechanical shutter is rated at 400,000 actuations — the same figure as the D4, D5 and D6.
| Camera | Year | Sensor | Rated Shutter | NEF Tag |
|---|---|---|---|---|
| Nikon D3 (2007) | 2007 | 12.1 MP FX | 300,000 | 0x00A7 |
| Nikon D4 | 2012 | 16.2 MP FX | 400,000 | 0x00A7 |
| Nikon D4S | 2014 | 16.2 MP FX | 400,000 | 0x00A7 |
| Nikon D5 | 2016 | 20.8 MP FX | 400,000 | 0x00A7 |
| Nikon D6 | 2020 | 20.8 MP FX | 400,000 | 0x00A7 |
The D4S does not display its shutter count on-screen. Every NEF RAW file, however, contains the total actuation count in MakerNote tag 0x00A7.
Note: a JPEG exported from the camera typically keeps the same MakerNote block, but NEF is always the most reliable source. If you shoot NEF+JPEG, use the NEF side of the pair.
The D4S was aimed at working professionals who routinely shoot tens of thousands of frames per assignment. Shutter counts on the used market are often much higher than on prosumer bodies of the same era.
| Shutter Count | % of Rated Life | Assessment |
|---|---|---|
| 0 – 30,000 | < 8 % | Very low — near-new condition |
| 30,000 – 100,000 | 8 – 25 % | Low use for a professional body |
| 100,000 – 250,000 | 25 – 63 % | Normal use for a working D4S |
| 250,000 – 400,000 | 63 – 100 % | Heavy use — still fine, price accordingly |
| 400,000 + | 100 %+ | Past rated life — budget for shutter replacement |
The good news: because Nikon rated the D4S very conservatively, shutters routinely last well beyond 400,000 cycles. The bad news: replacement cost at a Nikon service centre is typically €400–600, so factor this in when negotiating a high-count body.
The D4S writes images in Nikon's NEF RAW format, based on TIFF with a Nikon-specific MakerNote block. ShutterCount parses the TIFF IFD structure, locates the Nikon MakerNote, and reads the image count from tag 0x00A7 (ShutterCount).
All processing is done locally in your browser — the file never leaves your device. This is the same method used by every reliable Nikon shutter count tool, including the popular desktop utilities.
Shoot a NEF frame and drop it into shuttercount.app. The count is read from MakerNote tag 0x00A7 directly in your browser.
Nikon rates the D4S at 400,000 actuations — matching the D4, D5 and D6. This is a conservative figure, and well-maintained D4S bodies often exceed it significantly.
Only Nikon authorised service centres can reset the counter, typically after a physical shutter replacement. Third-party EXIF editors cannot alter the in-camera hardware counter. Always verify from an original NEF file.
Nikon has never officially said, but it follows the same "S" suffix Nikon uses for mid-cycle refreshes (D2H → D2Hs, D3 → D3S). The D4S delivers a meaningful refinement of the D4, with faster processing, Group AF and improved high-ISO performance.
Depends on your priorities. The D5 has a newer 20.8 MP sensor, 153-point AF system, faster 12 fps burst and 4K video. The D4S is cheaper, weighs slightly less, has a slightly more reliable battery life on its EN-EL18a pack, and is often found with lower shutter counts relative to its professional peers. For stills-focused sports and wildlife on a budget, the D4S remains an outstanding value.
