What To Know
- The dynamic range of a camera refers to its ability to capture detail in both the brightest and darkest areas of a scene.
- The Canon EOS 77D has a battery life of approximately 600 shots per charge, while the 850D has a battery life of approximately 800 shots per charge.
- If you are looking for a camera that is easy to use and has a long battery life, the 850D is the better choice.
The Canon EOS 77D and 850D are two popular DSLR cameras that are often considered for astrophotography. Both cameras offer a range of features that make them well-suited for capturing stunning images of the night sky. However, there are some key differences between the two cameras that may make one a better choice for your needs.
Image Quality: Resolution and Dynamic Range
The Canon EOS 77D has a 24.2-megapixel APS-C sensor, while the 850D has a 24.1-megapixel APS-C sensor. The difference in resolution is negligible, and both cameras will produce sharp, detailed images.
The dynamic range of a camera refers to its ability to capture detail in both the brightest and darkest areas of a scene. The Canon EOS 77D has a dynamic range of 13.5 stops, while the 850D has a dynamic range of 12.3 stops. This means that the 77D is better able to capture detail in scenes with a wide range of brightness levels, such as a starry night sky.
ISO Performance: Capturing Faint Stars
ISO performance is important for astrophotography because it allows you to capture images in low-light conditions without introducing excessive noise. The Canon EOS 77D has a native ISO range of 100-25600, which can be expanded to 51200. The 850D has a native ISO range of 100-25600, which can be expanded to 51200.
Both cameras perform well at high ISOs, but the 77D has a slight edge in terms of noise reduction. This means that you can capture images with the 77D at higher ISOs without sacrificing too much image quality.
Focusing: Precision for Starry Skies
Accurate focusing is essential for capturing sharp images of stars. The Canon EOS 77D has a 45-point autofocus system, while the 850D has a 88-point autofocus system. The 850D’s autofocus system is more advanced and offers better coverage across the frame. This makes it easier to focus on stars, even when they are located in the corners of the frame.
Battery Life: Endurance for Long Nights
Battery life is an important consideration for astrophotography, as you may be shooting for hours at a time. The Canon EOS 77D has a battery life of approximately 600 shots per charge, while the 850D has a battery life of approximately 800 shots per charge. The 850D has a longer battery life, which gives you more freedom to shoot without worrying about running out of power.
Ergonomics: Comfort and Control
Ergonomics is important for any camera, but it is especially important for astrophotography. You will often be shooting in uncomfortable positions for long periods of time, so it is important to have a camera that is comfortable to hold and use.
The Canon EOS 77D and 850D both have a comfortable grip and well-placed controls. However, the 850D has a slightly larger grip and a more pronounced thumb rest, which makes it more comfortable to hold for extended periods of time.
Connectivity: Sharing Your Images
The Canon EOS 77D and 850D both offer a range of connectivity options, including Wi-Fi, Bluetooth, and NFC. This allows you to easily share your images with your friends and family, or upload them to social media.
Which Camera is Right for You?
The Canon EOS 77D and 850D are both excellent cameras for astrophotography. The 77D offers better image quality and ISO performance, while the 850D offers better autofocus and battery life.
Ultimately, the best camera for you will depend on your individual needs and preferences. If you are looking for the best possible image quality, the 77D is the better choice. If you are looking for a camera that is easy to use and has a long battery life, the 850D is the better choice.
The Bottom Line: Making an Informed Decision
The Canon EOS 77D and 850D are both excellent cameras for astrophotography. By understanding the key differences between the two cameras, you can make an informed decision about which one is right for you.
