What To Know
- The D810 has a native ISO range of 64-12,800, expandable to 32-51,200, while the D850 has a native ISO range of 64-25,600, expandable to 32-102,400.
- The dynamic range refers to the camera’s ability to capture a wide range of tones from the brightest highlights to the darkest shadows.
- This difference is not significant in most real-world astrophotography scenarios, but it may be noticeable in extreme situations, such as capturing a bright moonlit landscape or a faint nebula against a dark background.
For astrophotographers, the choice between the Nikon D810 and D850 cameras is a crucial one. Both cameras offer exceptional capabilities for capturing the wonders of the night sky, but they also have distinct strengths and weaknesses. In this comprehensive comparison, we’ll delve into the key features and performance aspects of the Nikon D810 vs D850 for astrophotography, helping you make an informed decision.
Sensor and Resolution
The Nikon D810 features a 36.3-megapixel full-frame CMOS sensor, while the D850 boasts a 45.7-megapixel full-frame BSI CMOS sensor. The higher resolution of the D850 offers finer detail and the ability to create larger prints or crop images more aggressively without sacrificing quality. However, the larger pixel size of the D810 (4.88µm vs 4.35µm) provides slightly better low-light sensitivity and dynamic range.
Sensitivity and Noise Performance
Both the D810 and D850 have impressive sensitivity ranges, but the D850 has a slight edge in noise performance. The D810 has a native ISO range of 64-12,800, expandable to 32-51,200, while the D850 has a native ISO range of 64-25,600, expandable to 32-102,400. At higher ISO settings, the D850 exhibits less noise, resulting in cleaner and more detailed images, especially in long exposures.
Dynamic Range
The dynamic range refers to the camera’s ability to capture a wide range of tones from the brightest highlights to the darkest shadows. The D810 has a dynamic range of approximately 14.5 stops, while the D850 has a slightly wider dynamic range of approximately 15 stops. This difference is not significant in most real-world astrophotography scenarios, but it may be noticeable in extreme situations, such as capturing a bright moonlit landscape or a faint nebula against a dark background.
Long Exposure Performance
Long exposures are essential in astrophotography to capture faint objects and reduce noise. Both the D810 and D850 offer built-in intervalometer modes for long-duration time-lapse photography. However, the D850 has a slight advantage in its shutter life, with a rating of 200,000 actuations compared to the D810’s 150,000 actuations. This means the D850 can handle more extended shooting sessions without the risk of shutter failure.
Autofocus and Tracking
Autofocus precision is crucial for capturing sharp stars in astrophotography. The D810 features a 51-point AF system, while the D850 has a more advanced 153-point AF system. The D850’s AF system is faster and more accurate, especially in low-light conditions. It also has a dedicated “Group-Area AF” mode designed specifically for astrophotography, which helps to maintain focus on stars as they move across the sky.
Connectivity and Ergonomics
Both the D810 and D850 offer comprehensive connectivity options, including Wi-Fi, Bluetooth, and GPS. The D850 has a slightly larger and more comfortable grip, making it more ergonomic for extended shooting sessions. It also has a dedicated “Fn2” button that can be customized to quickly access frequently used settings in astrophotography, such as long exposure noise reduction or focus peaking.
Other Features for Astrophotography
In addition to the core features mentioned above, the Nikon D810 and D850 offer several specific features tailored for astrophotography:
- Electronic Front Curtain Shutter (EFCS): Both cameras have an EFCS, which eliminates vibrations caused by the mechanical shutter, reducing image blur during long exposures.
- Long Exposure Noise Reduction (LENR): Both cameras offer LENR to reduce noise in long exposures by taking a second dark frame and subtracting it from the main image.
- Focus Peaking: Both cameras have focus peaking, which highlights in-focus areas to aid in manual focus in low-light conditions.
- Bulb Mode: Both cameras offer a Bulb mode for unlimited exposure times, allowing for capturing star trails or other long-duration phenomena.
Recommendations
The choice between the Nikon D810 and D850 for astrophotography depends on your specific needs and budget. If you prioritize resolution and image quality in low-light conditions, the D810 remains a solid choice. However, if you need a camera with higher resolution, better noise performance, faster autofocus, and more advanced features for astrophotography, the D850 is the clear winner.
