Why know the mileage of the full frame SONY DSLR-A850

As a connoisseur of good optics and high-quality sensors, I always pick up the SONY DSLR-A850 with trepidation. At one time, this model made full frame accessible to many enthusiasts. This is a real tank that feels like a monolithic piece of magnesium alloy in your hands. It's impossible not to fall in love with its bright and huge optical viewfinder!

Professional-grade shutter endurance

The heart of the A850 is an excellent 24.6 megapixel full-frame sensor. Two BIONZ processors are responsible for data processing. The continuous shooting speed is 3 frames per second. The shutter installed here is full-size, with powerful springs and metal slats, designed for many years of professional use. The slam of the mirror and shutter on this camera sounds like a gunshot - solid and powerful.

Reading frame counter from EXIF ​​metadata

Since the camera belongs to a serious segment, the manufacturer approached the diagnostic issue responsibly. The device’s software code contains a continuous monitoring function: the total counter of captured frames is carefully recorded in the depths of the EXIF ​​data (MakerNotes) of each photo. This allows you to find out the exact operating time of the mechanics at any time.
