What To Know
- This difference in battery life is due to the fact that the A77 II has a smaller sensor and a more efficient processor.
- The A99, on the other hand, has a larger full-frame sensor, a more advanced autofocus system, and a more robust build.
- If you are looking for a camera that is small and lightweight, and you want to shoot fast-moving subjects, the A77 II is the better choice.
The world of photography is constantly evolving, with new technologies and advancements emerging all the time. Two of the most popular camera types on the market today are mirrorless cameras and DSLRs. In this blog post, we’ll be comparing two of the top models from each category: the Sony A77 II and the Sony A99.

Design and Ergonomics
The A77 II and A99 have very different designs, reflecting their different target audiences. The A77 II is a more compact and lightweight camera, making it ideal for travel and everyday use. The A99, on the other hand, is a larger and heavier camera, but it offers a more robust build and better ergonomics.
Both cameras have a weather-sealed design, making them resistant to dust and moisture. This makes them ideal for use in harsh conditions, such as rain or snow.
Image Quality
One of the most important factors to consider when choosing a camera is image quality. Both the A77 II and A99 have excellent image quality, but the A99 has a slight edge due to its larger full-frame sensor.
The A99’s full-frame sensor provides a wider dynamic range, which means it can capture more detail in both the shadows and highlights. It also has a better signal-to-noise ratio, which means that images will be less noisy, especially at high ISO settings.
Autofocus
The A77 II and A99 both have excellent autofocus systems, but the A99’s system is slightly faster and more accurate. The A99 uses a hybrid autofocus system that combines phase-detection and contrast-detection autofocus, which gives it a wider range of focusing capabilities.
The A77 II’s autofocus system is also very good, but it is not quite as fast or accurate as the A99’s system. However, the A77 II does have a slight advantage in low-light autofocus, thanks to its larger APS-C sensor.
Continuous Shooting Speed
The A77 II and A99 both have fast continuous shooting speeds, but the A77 II has a slight edge. The A77 II can shoot at up to 12fps, while the A99 can shoot at up to 10fps.
This difference in continuous shooting speed may not seem like much, but it can be significant for sports and wildlife photography. If you need to capture fast-moving subjects, the A77 II is the better choice.
Viewfinder
The A77 II and A99 have very different viewfinders. The A77 II has an electronic viewfinder (EVF), while the A99 has an optical viewfinder (OVF).
EVFs are becoming increasingly popular, as they offer a number of advantages over OVFs. EVFs are brighter and more detailed, and they can provide real-time information about the exposure and other camera settings.
OVFs, on the other hand, are more traditional and offer a more direct view of the scene. They are also less likely to cause eye strain, especially when shooting in bright sunlight.
Battery Life
The A77 II and A99 have very different battery lives. The A77 II has a CIPA-rated battery life of 500 shots, while the A99 has a CIPA-rated battery life of 490 shots.
This difference in battery life is due to the fact that the A77 II has a smaller sensor and a more efficient processor. If you need a camera with long battery life, the A77 II is the better choice.
Which Camera is Right for You?
The Sony A77 II and A99 are both excellent cameras, but they are designed for different types of photographers. The A77 II is a more compact and lightweight camera with a faster continuous shooting speed and better battery life. The A99, on the other hand, has a larger full-frame sensor, a more advanced autofocus system, and a more robust build.
If you are looking for a camera that is small and lightweight, and you want to shoot fast-moving subjects, the A77 II is the better choice. If you are looking for a camera with the best possible image quality and autofocus performance, the A99 is the better choice.
Alternative Considerations
If you are still not sure which camera is right for you, here are a few alternative considerations:
- Sony A7 III: The A7 III is a newer model than the A77 II, and it offers a number of advantages, including a higher resolution sensor, better autofocus, and improved image quality.
- Sony A7R III: The A7R III is a higher-resolution version of the A7 III, with a 42.4MP sensor. It is a great choice for photographers who need the highest possible image quality.
- Sony A9: The A9 is a professional-grade mirrorless camera with a stacked CMOS sensor and a blazing-fast continuous shooting speed of 20fps. It is the best choice for photographers who need the best possible performance.
