Nikon D90 - a legendary camera on the secondary market

Nikon D90 made history as the world's first DSLR camera with video capabilities. This historical fact, combined with an outstanding 12.3 megapixel sensor and excellent ergonomics, created a huge fan base that still appreciates this camera. Today, almost two decades after its release, the D90 can be bought for very modest money. But it is precisely this advanced age that makes checking the mileage not just a recommendation, but an absolute necessity.

Over such a long life, the camera could change a dozen owners. Some used it as a photo-school tool, some made videos for YouTube in an era when it was a novelty, some passed it on to children for teaching. Each of these scenarios means a different level of wear and tear. If you buy a D90 based on looks alone, you are almost guaranteed to end up with a camera with an exhausted shutter life.

Age-related wear and tear on the shutter of an old DSLR

The Nikon D90 shutter is designed for approximately 100,000 guaranteed operations - a standard indicator for advanced amateur equipment of that time. Many specimens actually withstood 150,000 or more. But here you need to take into account a fundamentally important factor: the age of the materials.

Even if the meter shows a modest 30-40 thousand frames, the lubricants inside the mechanism could have degraded over the years. The springs lose their elasticity, the seals dry out. Therefore, when purchasing a D90, it is recommended to combine a mileage check with a general inspection at a service center, which will assess the general technical condition of the mechanics.

Reading Nikon's historical EXIF ​​tag

Despite its venerable age, the D90 faithfully recorded every actuation of its shutter. The first generation EXPEED processor wrote a ShutterCount to a hidden MakerNotes block for every file it saved, both RAW (.NEF) and JPEG.

The Nikon D90's MakerNotes format is well understood. Our service supports reading data from older versions of the Nikon EXIF ​​structure. For successful diagnostics, you will need the original, unedited file directly from the memory card - preferably in NEF format, as it better preserves the full package of service metadata.
