What To Know
- The A7 III can capture up to 177 JPEGs or 89 RAW images in a single burst, while the A77 II is limited to 60 JPEGs or 26 RAW images.
- The A77 II is a capable APS-C camera with a traditional DSLR design, while the A7 III is a full-frame powerhouse with advanced features and exceptional image quality.
- However, if you prefer the ergonomics of a DSLR-style camera, prioritize affordability, or are primarily interested in still photography with a crop factor, the Sony A77 II remains a solid option.
In the realm of mirrorless cameras, the Sony A77 II and A7 III stand out as formidable contenders. Both cameras boast impressive features and capabilities, but they cater to distinct photography needs. In this comprehensive comparison, we delve into the key differences between the Sony A77 II and A7 III to help you make an informed decision about which one aligns best with your photographic aspirations.
Sensor and Image Quality
The Sony A77 II features a 24.3-megapixel APS-C CMOS sensor, while the A7 III boasts a 24.2-megapixel full-frame CMOS sensor. Full-frame sensors offer several advantages over APS-C sensors, including a wider field of view, shallower depth of field, and better low-light performance. In this regard, the A7 III has a clear edge over the A77 II in terms of image quality and overall versatility.
Autofocus System
Both cameras employ advanced autofocus systems, but they differ in their implementation. The A77 II utilizes a 79-point phase-detection autofocus system, while the A7 III boasts an impressive 693-point phase-detection autofocus system. The A7 III’s autofocus system is significantly faster, more accurate, and more responsive, enabling it to track subjects with precision even in challenging lighting conditions.
Burst Shooting and Buffer Capacity
The A77 II offers a burst shooting speed of 12 frames per second (fps), while the A7 III can shoot at a blazing 10 fps in continuous autofocus mode. However, the A7 III’s buffer capacity is far superior to the A77 II’s. The A7 III can capture up to 177 JPEGs or 89 RAW images in a single burst, while the A77 II is limited to 60 JPEGs or 26 RAW images. This makes the A7 III more suitable for capturing fast-paced action or sequences of rapidly moving subjects.
Video Capabilities
The Sony A77 II offers Full HD video recording at up to 60 fps, while the A7 III can record 4K video at up to 30 fps. Additionally, the A7 III supports 10-bit 4:2:2 internal recording, which provides greater color depth and flexibility in post-production. The A7 III also features advanced video features such as S-Log3 gamma profiles and HLG (Hybrid Log-Gamma) for enhanced dynamic range and color grading capabilities.
Stabilization and Weather Resistance
The Sony A77 II lacks in-body image stabilization, relying solely on lens-based stabilization. In contrast, the A7 III features a 5-axis in-body image stabilization system that compensates for camera shake, making it ideal for handheld shooting or using telephoto lenses. Both cameras offer weather-resistant construction, but the A7 III’s more robust weather sealing makes it better suited for use in inclement conditions.
Ergonomics and Usability
The A77 II features a traditional DSLR-style body with a pentaprism viewfinder and a large, comfortable grip. The A7 III, on the other hand, has a more compact and lightweight design with an electronic viewfinder (EVF). While the EVF may take some getting used to for DSLR users, it offers several advantages, including real-time exposure and focus preview.
Connectivity and Storage
Both cameras offer a range of connectivity options, including Wi-Fi, NFC, and Bluetooth. The A7 III has the added advantage of a USB-C port, which allows for faster data transfer and charging. Both cameras support dual SD card slots for increased storage capacity and redundancy.
Wrap-Up: Unveiling the Superior Choice
The Sony A77 II and A7 III represent two distinct approaches to mirrorless photography. The A77 II is a capable APS-C camera with a traditional DSLR design, while the A7 III is a full-frame powerhouse with advanced features and exceptional image quality.
For photographers seeking a versatile camera with excellent autofocus, burst shooting capabilities, and video performance, the Sony A7 III is the clear choice. Its full-frame sensor, advanced autofocus system, and robust video features make it an ideal camera for a wide range of photographic genres, from portraits to wildlife to sports.
However, if you prefer the ergonomics of a DSLR-style camera, prioritize affordability, or are primarily interested in still photography with a crop factor, the Sony A77 II remains a solid option.
