Nikon D4S shutter count determination
Nikon embeds information on the number of actuations that the shutter of a D4S has undertaken in EXIF data. These metadata are saved alongside each and every image file. EXIF-readers, such as the App below, can read this information and, thus, convey how many shots a camera has taken so far. The shutter count is particularly useful as an indicator of how intensively a Nikon D4S has been used and what remains in terms of the lifespan of the camera shutter.
How many images has my D4S taken up to now?
In order to find out how many shots your camera has taken, just upload a new, unedited image using the dialog box below. Both JPG and RAW file formats will work, with smaller jpg-files uploading faster. Your image will be deleted from the server once the exif-information has been obtained.

The shutter count corresponds to the number of images your Nikon D4S has captured with its mechanical shutter. Mechanical focal-plane shutters consist of a pair of light-tight curtains that move to uncover the sensor during the exposure time. Every actuation, that is every shutter opening and closing, will cause some minimal wear and tear that will eventually result in malfunction and the need for repair or replacement. A shutter can fail completely on one incident, but more likely it will deteriorate gradually. It becomes unreliable when shooting at high shutter speeds or the first and second curtains get out of sync, so that the shutter speed becomes inaccurate. If these warning signs appear, it is time to take action and get your camera shutter replaced. Shutter replacement costs generally fall into the range of US$200 to US$400, plus the hassle of having to send the camera to the Nikon service center.
That said, the actuation count is not just an indicator on whether or not the shutter might soon need to be replaced, but more generally on the overall condition of your D4S. A high shutter count indicates that the camera has been intensively used and probably also been subject to more bumps and knocks, more frequent exposure to dust, and more recurrent usage in the rain than a D4S that has been kept in a drawer most of the time and therefore shows a low actuation count. As a result, second-hand buyers on Ebay or Craigslist are willing to offer a higher price for a D4S with a low number of shutter releases than for one with a high actuation count.
What is the shutter life expectancy of my Nikon D4S?
Shutter life ratings differ across cameras, ranging from 50 000 shots for entre-level models to 500 000 actuations for some professional cameras. For the D4S, Nikon claims a shutter life expectancy of 400 000 actuations. However, it is important to note that the shutter rating does not provide a guarantee of a certain photo count before shutter maintenance or replacement are needed. The shutter might fail earlier, or it could last longer without causing any problems. The shutter rating should, thus, be seen as representing a statistically determined failure average or Mean Time Before Failure.
Most photographers are unlikely to come close to the shutter life expectancy of their imaging tools. For example, if one were to take 400 photos each and every day, this would mean 12 000 actuations per month and 144 000 shots per year. In this case, one would reach a count of 400 000 images in about three years. Few people use their cameras as regularly and intensively, and if they do, their cameras might well be up for a replacement after three years anyway for reasons other than shutter failure. Nevertheless, shutters do sometimes break down during photo sessions and such adverse events are getting more likely as the shutter count increases.
