All New Nikon Shutter Count Program (for Nikon D850)

The Nikon D850 is the first Nikon DSLR that utilizes both conventional mechanical shutter and elcetronic shutter.

The current shutter counting tools in the market show only the sum of both electronic and mechanical shutter counts.

Unlike the electronic shutter, mechanical shutter has a life span and thus we tried to develop a tool that would separately show the shutter counts of mechanical and electronic shutter.

We analyzed the NEF file data and were able to distinguish the count of mechanical shutter and electronic shutter.

Due to the interchangeable shutter system of D850, users might be confused when estimating the life span or durability of one’s equipment based on the shutter count.

We expect that our program may aid in accurate estimation of the status of the camera and are glad that we could help other users at such an early stage of product release.

Special thanks to Dr. Visual Y.S for his contribution in developing such a great tool.

Please read the following articles carefully before using this tool!

1. This program is a freeware but the intellectual property rights belong to Jang Hee Lee and Yonsang Cho, and thus commercial use is prohibited.

2. This program is only for Nikon DSLR cameras (Not for mirrorless cameras)

3. This program will only show the count of mechanical shutter for cameras prior to D850.

4. Starting with D850, actuations from each shutter (electronic/mechanical) will be displayed seperately, along with the date of the photo to increase the reliability of review.

5. Due to compatibility issue with third-party lenses, there were reports of false shutter count in some cameras.
If there is a discrepancy between the actual shutter actuation and the shutter count shown in our program, we recommend that you consult with Nikon service center directly.

6. This program has undergone numerous tests and has proven to be stable. However the program is not liable to any conflict caused by the shutter count calculation and users should use this program at ones own discretion.

7. It is possible to only NEF file.
