What To Know
- The 7D Mark II has a native ISO range of 100-16000, expandable to 51200, while the 7D has a native ISO range of 100-6400, expandable to 12800.
- However, the Mark II offers a number of advantages over the original 7D, including a higher resolution sensor, better ISO performance, a more advanced autofocus system, a faster burst shooting speed, more robust weather sealing, and longer battery life.
- The Canon 7D Mark II has a faster and more precise autofocus system than the 7D, making it easier to focus on stars and other celestial objects in low-light conditions.
The Canon 7D series has been a popular choice among astrophotography enthusiasts for many years. The latest models, the 7D Mark II and the original 7D, offer a range of features that make them well-suited for capturing stunning images of the night sky. In this blog post, we will compare the Canon 7D Mark II vs Mark I in-depth to help you decide which camera is the best choice for your astrophotography needs.
Sensor and Image Quality
The 7D Mark II features a 20.2-megapixel APS-C CMOS sensor, while the 7D has an 18-megapixel APS-C CMOS sensor. Both sensors are capable of producing high-quality images, but the Mark II has a slight edge in terms of resolution and dynamic range. This means that the Mark II can capture more detail in both bright and dark areas of the sky, resulting in more vibrant and realistic images.
ISO Performance
ISO performance is critical for astrophotography, as it allows you to capture images in low-light conditions without introducing excessive noise. The 7D Mark II has a native ISO range of 100-16000, expandable to 51200, while the 7D has a native ISO range of 100-6400, expandable to 12800. The Mark II’s expanded ISO range gives it a significant advantage in capturing images in extremely dark conditions.
Autofocus System
The autofocus system is another important consideration for astrophotography, as it determines how quickly and accurately the camera can focus on stars and other celestial objects. The 7D Mark II features a 65-point all cross-type autofocus system, while the 7D has a 19-point all cross-type autofocus system. The Mark II’s more advanced autofocus system provides faster and more precise focusing, even in low-light conditions.
Burst Shooting Speed
Burst shooting speed is essential for capturing multiple images of the night sky in a short period of time. The 7D Mark II has a maximum burst shooting speed of 10 frames per second (fps), while the 7D has a maximum burst shooting speed of 8 fps. The Mark II’s faster burst shooting speed allows you to capture more images of meteors, star trails, and other transient celestial events.
Weather Sealing
Weather sealing is an important feature for astrophotographers who shoot in challenging conditions. The 7D Mark II has a more robust weather sealing system than the 7D, making it more resistant to dust, moisture, and extreme temperatures. This makes the Mark II a better choice for shooting in rainy or dusty environments.
Battery Life
Battery life is another important consideration for astrophotographers who often shoot for extended periods of time. The 7D Mark II has a longer battery life than the 7D, with a CIPA rating of 650 shots per charge compared to 400 shots per charge. This means that you can shoot for longer periods of time without having to worry about running out of battery power.
Key Points: Which Camera is Right for You?
Both the Canon 7D Mark II and the 7D are excellent cameras for astrophotography. However, the Mark II offers a number of advantages over the original 7D, including a higher resolution sensor, better ISO performance, a more advanced autofocus system, a faster burst shooting speed, more robust weather sealing, and longer battery life. If you are serious about astrophotography, the Canon 7D Mark II is the best choice for your needs.
