The Alpha a7 III Mirrorless Digital Camera from Sony is a product well refined for improved speed and low-light performance also know for its updated sensor design, the full-frame 24.2MP Exmor R BSI CMOS sensor and BIONZ X image processor combine to produce an exquisite 10 fps continuous shooting rate and improved auto-focus performance for speed, more reliable subject tracking along with wide range imagery. This updated Fast Hybrid AF System employs a combination of 693 phase-detection points and 425 contrast-detection areas for faster capturing and focusing in a variety of lighting conditions, and also maintains focus on subjects more effectively. In addition to speed and AF, the processing improvements also help to realize greater image clarity and reduced noise throughout the sensitivity range from ISO 100-51200, which can increased to ISO 50-204800.This product is sold for nearly $2000.
