The world of photography has been abuzz with the release of two highly anticipated cameras: the Sony A77 and the Canon 7D. Both cameras offer impressive features and capabilities, but which one is right for you? In this comprehensive comparison, we’ll pit the Sony A77 against the Canon 7D to determine which camera reigns supreme.
Sensor and Image Quality
The Sony A77 boasts a 24.3-megapixel APS-C CMOS sensor, while the Canon 7D features an 18-megapixel APS-C CMOS sensor. Despite the difference in resolution, both cameras deliver exceptional image quality with vibrant colors, sharp details, and low noise levels. However, the Sony A77’s higher resolution allows for larger prints or more flexibility in cropping.
Autofocus and Speed
The Sony A77 and Canon 7D both excel in autofocus performance. The A77 utilizes a hybrid autofocus system that combines phase-detection and contrast-detection points, providing fast and accurate focusing. The 7D, on the other hand, employs a dedicated 19-point cross-type autofocus system, known for its precision and speed. Both cameras offer continuous autofocus modes for capturing fast-moving subjects.
Burst Shooting and Buffer
The Sony A77 takes the edge in burst shooting, capable of capturing up to 12 frames per second (fps) for up to 60 shots in JPEG or 28 shots in RAW. The Canon 7D is not far behind, offering a burst rate of 8 fps for up to 126 shots in JPEG or 25 shots in RAW. The A77’s larger buffer allows for longer continuous shooting bursts.
Viewfinder and LCD Screen
The Sony A77 features an electronic viewfinder (EVF) with a resolution of 2.36 million dots. The EVF provides a real-time preview of the image, including exposure and white balance settings. The Canon 7D, on the other hand, has a pentaprism optical viewfinder with a 100% field of view. Both cameras have large and bright LCD screens for framing and reviewing images.
Video Capabilities
Both the Sony A77 and Canon 7D offer impressive video capabilities. The A77 can capture full HD video at up to 60 fps, while the 7D supports 1080p video at up to 30 fps. Both cameras feature manual controls for exposure and focus, allowing videographers to customize their recordings.
Battery Life and Weather Sealing
The Sony A77 has a slightly longer battery life than the Canon 7D, with a CIPA rating of 950 shots per charge compared to 800 shots for the 7D. However, the 7D features a more robust weather sealing, making it better suited for harsh weather conditions.
The Bottom Line: The Ultimate Verdict
The Sony A77 and Canon 7D are both exceptional cameras with their own strengths and weaknesses. The A77 offers higher resolution, faster burst shooting, and a longer battery life, while the 7D excels in autofocus precision, weather sealing, and a dedicated optical viewfinder.
Ultimately, the best choice for you depends on your specific needs and preferences. If you prioritize image quality, burst shooting, and battery life, the Sony A77 is an excellent choice. However, if you require precise autofocus, weather resistance, and an optical viewfinder, the Canon 7D is the better option.
