What To Know
- The a72 has a hybrid autofocus system that combines phase-detection and contrast-detection autofocus, while the a7S has a pure contrast-detection autofocus system.
- The Sony a72 has a battery life of 350 shots per charge, while the a7S has a battery life of 380 shots per charge.
The Sony a72 and a7S are two of the most popular mirrorless cameras on the market. Both cameras offer excellent image quality, but they have different strengths and weaknesses. In this blog post, we will compare the Sony a72 and a7S in detail to help you decide which camera is right for you.
Sensor and Image Quality
The Sony a72 has a 24.2-megapixel Exmor R CMOS sensor, while the a7S has a 12.2-megapixel Exmor CMOS sensor. The a72’s sensor has a higher resolution, which means that it can capture more detail in images. However, the a7S’s sensor is more sensitive to light, which means that it can produce better images in low-light conditions.
Dynamic Range and Color Depth
The Sony a72 has a dynamic range of 14 stops, while the a7S has a dynamic range of 15 stops. This means that the a7S can capture more detail in both the highlights and shadows of an image. The a7S also has a higher color depth of 14 bits, compared to the a72’s 12 bits. This means that the a7S can produce more accurate and vibrant colors.
Video Capabilities
The Sony a72 and a7S are both capable of shooting 4K video. However, the a7S has a number of features that make it a better choice for videographers. These features include:
- A higher bit rate of 100 Mbps, compared to the a72’s 50 Mbps
- The ability to shoot in full-frame 4K, while the a72 can only shoot in APS-C 4K
- A built-in S-Log2 profile for capturing flat footage that can be color graded in post-production
- A headphone jack for monitoring audio
Autofocus and Performance
The Sony a72 and a7S both have excellent autofocus systems. The a72 has a hybrid autofocus system that combines phase-detection and contrast-detection autofocus, while the a7S has a pure contrast-detection autofocus system. The a72’s hybrid autofocus system is faster and more accurate than the a7S’s contrast-detection autofocus system, but the a7S’s autofocus system is still very good.
Battery Life
The Sony a72 has a battery life of 350 shots per charge, while the a7S has a battery life of 380 shots per charge. This means that the a7S has a slightly better battery life than the a72.
Price
The Sony a72 is priced at $1,999, while the a7S is priced at $2,999. This means that the a72 is a more affordable option than the a7S.
Summary: Choosing the Right Camera for Your Needs
The Sony a72 and a7S are both excellent cameras, but they are best suited for different types of photographers. The a72 is a great choice for photographers who need a high-resolution camera with excellent image quality. The a7S is a better choice for photographers who need a camera that can shoot in low-light conditions and that has advanced video capabilities.
