The Canon 7D and Sony A77 are two renowned cameras that have captivated the hearts of photographers seeking performance and versatility. As a DSLR and SLT (Single Lens Translucent) camera, respectively, they offer distinct approaches to image capture. This comprehensive comparison delves into the key differences and similarities between these photographic powerhouses, helping you make an informed decision.
Sensor and Image Quality
The Canon 7D boasts an 18.0-megapixel APS-C CMOS sensor, while the Sony A77 features a 24.3-megapixel APS-C Exmor CMOS sensor. The higher resolution of the A77 offers more detail in images, especially when cropping or printing large prints. However, the 7D’s larger pixels provide better low-light performance and dynamic range.
Autofocus and Speed
Canon’s 7D is renowned for its exceptional autofocus system, featuring 19 cross-type autofocus points. This allows for precise and fast focusing, even in challenging lighting conditions. The Sony A77, on the other hand, employs a Translucent Mirror Technology (SLT) with 19 autofocus points. While the SLT design provides continuous autofocus during live view and video recording, it may not be as reliable as the 7D’s dedicated autofocus system in certain situations.
Burst Shooting and Buffer
The Canon 7D excels in burst shooting, capturing up to 8 frames per second (fps) with a buffer capacity of 126 JPEGs or 25 RAW images. The Sony A77 offers a burst rate of 12 fps with a buffer capacity of 60 JPEGs or 15 RAW images. While the A77’s higher burst rate may seem impressive, its smaller buffer capacity limits continuous shooting for longer sequences.
Video Capabilities
Both the Canon 7D and Sony A77 offer full HD video recording at 1080p resolution. However, the 7D supports higher frame rates of 60 fps, while the A77 is limited to 30 fps. Additionally, the 7D has a built-in microphone jack, allowing for external audio recording.
Build and Ergonomics
The Canon 7D is built like a tank, featuring a rugged magnesium alloy body with weather sealing. It offers a comfortable grip and well-placed controls for easy handling. The Sony A77, while also durable, has a more compact and lightweight body. Its ergonomic design provides a comfortable shooting experience, but it may not be as weather-resistant as the 7D.
Features and Customization
The Canon 7D offers extensive customization options, including custom shooting modes and programmable buttons. It also has a built-in flash and a top-mounted LCD panel for quick access to camera settings. The Sony A77 has a simpler menu system and lacks some of the advanced customization options of the 7D. However, it features a built-in GPS receiver and a tilt-able LCD screen.
Price and Availability
The Canon 7D and Sony A77 were released in 2009 and 2011, respectively. They are both discontinued models, but used and refurbished units can be found online and in camera stores. The price varies depending on the condition and accessories included.
Key Points: The Verdict
The Canon 7D and Sony A77 are both excellent cameras with their own strengths and weaknesses. The 7D offers superior autofocus, burst shooting, and weather sealing, making it an ideal choice for action, wildlife, and sports photography. The A77 provides higher resolution, continuous autofocus during live view, and a more compact body, suitable for general-purpose photography and videography. Ultimately, the best choice depends on your specific needs and preferences.
