The a7 III is an entry level full frame mirrorless interchangeable lens camera (MILC) that only seems entry level because of its low price. The 24 MP imaging sensor does not give the a7 III claim to being close to the highest resolution full frame camera available, but this is still a significant resolution, one very adequate for many purposes. And, this imaging sensor has the mentioned high dynamic range and low noise qualities.

• Newly Developed Full-frame 24.2MP Back-Illuminated Exmor R CMOS Image Sensor with Evolved Image Processing
• Wide ISO range of 100 – 51200 (expandable to ISO 50 – 204800 for still images) and 15-Stop Dynamic Range at low sensitivities
• World Class AF system featuring 693 phase-detection AF points covering 93% of image area, 425 contrast AF points and fast and reliable Eye AF
• Continuous Shooting at up to 10 fps with either Mechanical Shutter or Silent Shooting and full Auto Focus/Auto Exposure tracking
• 5-axis optical in-body image stabilization with a 5.0 step shutter speed advantage
• High Resolution 4K Movie Shooting with full pixel readout and no pixel binning across full-width of full-frame sensor
• The longest rated battery life of any Mirrorless camera at 710 shots per charge
• Upgraded operability and functionality including addition of joystick for adjusting focus points, Dual SD Card Slots, SuperSpeed USB (USB 3.1 Gen 1) USB Type-C Terminal and more

Wider, faster, more steadfast AF performance

An evolved image processing system and α9 camera AF algorithms optimised for the α7 III improve AF speed, precision, and tracking performance. 693 phase-detection AF points and 425 contrast-detection AF points provide high-density wide-area coverage. AF speed improved by up to twice and more precise AF tracking performance let you capture and maintain focus on a quickly moving subject in unpredictable motion. The α7 III also autofocuses reliably down to EV-3 brightness.

Always keep the eye in focus

With new shutter charge unit and image processing system refinements, the α7 III can shoot continuously at up to 10 fps with AF/AE tracking (up to 8 fps with minimal display lag in live-view continuous shooting mode) for easy, stable shooting of even intensely active subjects. Up to approximately 177 JPEG images (standard) in full resolution, 89 compressed RAW images, or 40 uncompressed RAW images can be captured in one continuous burst. An electronic shutter allows silent, vibration-free shooting of wildlife and other sensitive situations when even slight noise can mean missing an ideal shot.

Clear, natural, realistic 4K movies

High-resolution full-frame 4K movies with full-pixel readout without pixel binning that condenses approximately 2.4 times the amount of data required for 4K movies (QFHD: 3840 x 2160) results in minimal moiré and jaggies. Advanced image processing makes it possible to record full-frame 4K movies with outstanding image quality in the mid-to-high ISO range, so you make the most of the 4K movie format’s unique potential in every shot. Super 35mm can also be selected, instead of full-frame mode, as needed.
