Semi-professional class standard: Nikon D300 diagnostics

Nikon D300 (2007) is rightfully considered one of the best semi-professional DSLRs in history. Flagship AF system technology (51 points!), a waterproof D3-level magnesium body, a fast EXPEED processor and an excellent 12.3-megapixel sensor - all this has made the D300 a favorite of serious enthusiasts and a working tool for professionals. This is what makes checking the mileage of a used D300 absolutely necessary.

The D300 was used for reporting, weddings, nature and sports. The speed of 6 fps (8 fps with the handle) meant that during an active day of work the mileage increased by thousands of frames. After almost 20 years on the secondary market, it is almost impossible to find a D300 with an "honest" history without inspection.

Semi-professional resource with flagship reliability

The D300 shutter is designed for 150,000 guaranteed operations - a record for the semi-professional class at that time. In practice, many copies exceeded 200 thousand. Instances with mileage up to 80 thousand are an excellent purchase. Over 150 thousand - requires a thorough inspection of the mechanics.

Reading EXIF ​​data from D300 NEF files

The hit count is written to the MakerNotes block of each NEF and JPEG. For diagnostics, you need the original file from the memory card without intermediate processing.
