SONY DSLR-A900 shutter life diagnostics

If there is one camera that has forever inscribed Sony's name in the professional DSLR hall of fame, it is the SONY DSLR-A900. As a craftsman, I take my hat off to the engineers who created this masterpiece. It is an uncompromising flagship that is still used by many studio and landscape photographers today due to its fantastic color.

Flagship characteristics and safety margin

The camera has an outstanding 24.6 MP full-frame sensor. The viewfinder with 100% frame coverage is one of the best in history! Despite the highest resolution for those years, two BIONZ processors allow the camera to produce 5 frames per second. The A900 bolt assembly is a masterpiece of engineering designed to withstand the extreme demands of professional use. The mechanics work with incredible precision and reliability.

Extracting accurate frame count from EXIF

As befits a device of this class, the manufacturer has ensured transparency of operation. Sony has implemented strict internal accounting: the counter of each movement of the shutter curtain is permanently recorded in the EXIF ​​service data (metadata) of the resulting image. No amount of software resets can hide the real history of this magnificent mechanism.
