Rotating screen and 16 megapixels: Nikon D5100 mileage diagnostics

Nikon D5100 (2011) is one of the best-selling amateur Nikons of its time. The rotatable display, 16.2-megapixel sensor with excellent dynamic range (inherited from the professional D7000) and affordable price have made it a hit among beginners and family photographers. On the secondary market, the D5100 is found very often - and, as a rule, with an unknown or rich history of use.

The audience for the D5100 is heterogeneous: some shot landscapes with it on weekends, others maintained an active photo blog with daily sessions. The rotating screen provoked shooting from non-standard angles and more active use of Live View and video. The age of the camera (more than 13 years) means that without checking the mileage, the purchase is a gamble.

Sensor from D7000 in an amateur body: shutter life

Despite the flagship sensor, the D5100 shutter is an amateur grade with an official life of 100,000 guaranteed operations. In practice, many copies worked up to 150 thousand. Mileage up to 40 thousand is a great buy. From 70 thousand and above - bargaining and technical inspection are required.

Reading the EXIF ​​counter from D5100 NEF files

The hit count is written to the MakerNotes block of each NEF and JPEG file. The data is protected from being reset. For diagnostics, you need the original file from the memory card without processing in editors.
