Nikon D810A Bewertung | 108 Daten im Vergleich

The Nikon D810A is a highly capable 36.3-megapixel full-frame DSLR engineered specifically for astrophotography by modifying the highly successful standard D810 baseline. Its primary advantage is a modified infrared-cut filter that increases hydrogen-alpha spectral line transmission by approximately four times, allowing it to capture the vibrant red hues of emission nebulae with exceptional detail. Reviewers highlighted the addition of a dedicated long-exposure manual mode (M*) offering preset shutter times up to 900 seconds, an advanced built-in intervalometer that handles up to 9,999 frames, a more sensitive Live View for easier star focusing, and an electronic front-curtain shutter that entirely eliminates mechanical vibrations to prevent image blur. During testing, these features successfully produced sharp, high-resolution deep-sky images of objects like the Heart and Soul Nebulae. However, the specialized nature of the camera introduces a few notable downsides and technical trade-offs. The modified filter causes a slight pink color cast during daytime photography, which requires the user to correct images via custom presets in post-processing software. Mechanically, the camera lacks an articulated rear display screen, making framing difficult when pointed directly skyward,...

The Nikon D810a is a 36-megapixel, full-frame camera specifically tailored for astrophotography, distinguishing itself from the standard D810 with a factory-modified infrared (IR) cutoff filter. This specialized filter transmits four times more hydrogen-alpha (H-alpha) light at the 656-nanometer wavelength, allowing it to capture the vivid red nebulosities and faint celestial structures along the Milky Way that stock digital cameras usually block. In performance testing against a stock Nikon D750, the D810a recorded noticeably more and fainter red nebulosity, while successfully minimizing mirror box vignetting/shadowing compared to older camera bodies. Furthermore, despite initial industry fears that smaller 4.9-micron pixels would compromise noise levels, the camera's EXPEED 4 processor manages noise superbly, offering extremely clean dark frames with no edge glows and keeping baseline noise only about one f-stop higher than the lower-resolution D750.

The ePHOTOzine review of the 36.3-megapixel Nikon D810A identifies it as a specialized full-frame DSLR designed for astrophotography, featuring a modified optical filter with four times greater hydrogen-alpha (656nm) sensitivity than standard cameras. Key pros include excellent low-light performance with a 1 to 2-stop noise advantage over the standard D810, an M* manual exposure mode allowing for 900-second exposures, and a robust, weather-sealed body. Conversely, the review notes that the high red-light sensitivity results in inaccurate colors during daylight photography. Additional cons include the removal of base ISO 64 and 32, sluggish live view focusing, a noisy, low-light-sensitive virtual preview screen, and a lack of illuminated buttons for dark environments.

summary of the Nikon D810a review: Review Summary The Nikon D810a is a high-end, full-frame 36.3-megapixel DSLR specifically engineered for astrophotography. Its standout feature is a modified long-wavelength filter that captures four times more hydrogen-alpha light than a standard D810, making it exceptionally sensitive to the vibrant red emission nebulae found in deep-sky objects. Reviewer tests show that Nikon has resolved old issues like the "star eater" noise-reduction blurring algorithm, resulting in top-tier image quality with excellent low-noise performance, very low dark current, and a massive dynamic range that excels at capturing high-contrast subjects like galaxies without data loss. For field use, it includes highly functional tools like an electronic front-curtain shutter to stop mechanical vibration, a dedicated M* mode allowing long manual exposures up to 900 seconds, and an expanded intervalometer capable of shooting up to 9,999 continuous frames for time-lapses and starscapes. Despite its stellar astrophotographic performance, the camera has notable limitations. The prominent physical downside is its fixed, non-articulated LCD screen, making it difficult to view and change settings when a telescope is pointed straight overhead. Because...

The Nikon D810A is a specialized 36-megapixel full-frame DSLR tailored for astrophotography, matching the clean high-ISO performance of the 24-megapixel D750 while heavily outperforming the standard D810 in low-light noise reduction. A major benefit of this model is its custom infrared (IR) filter, which is optimized to capture H-alpha narrowband infrared light emissions, making red nebulae and the colors of the Milky Way pop vividly in comparison to standard camera bodies. Additionally, it features a highly convenient "M* manual mode" that allows photographers to select long exposure times beyond 30 seconds (up to 900 seconds) directly in-camera without requiring an external remote timer. However, the specialized IR filter introduces several notable downsides for versatile shooting conditions. Daytime photography often suffers from an unnatural red or warm color cast on landscapes, rocks, and water, making the camera poorly suited for regular use outside of nighttime environments. At night, this filter can cause light pollution to shift from an orange glow to a yellow hue. It also creates tricky artifacts under certain conditions, such as producing a heavy, problematic red cast around...

The Cloudy Nights forum review highlights the Nikon D810A as a specialized full-frame camera body that excels at deep-sky astrophotography due to its extremely low thermal noise, which prevents grain during long exposures. Key advantages include significantly higher sensitivity to H-alpha red wavelengths for capturing nebulae, excellent high ISO performance, and a built-in intervalometer for automated sequencing. Conversely, users identified drawbacks such as a 30% higher readout noise floor at ISO 1600 compared to the D800, making it less efficient for short-exposure astro-landscapes, and a higher base setting of ISO 200. Practical design limitations include a fixed, non-tilting LCD screen, which complicates framing, along with minor edge vignetting.

The ePHOTOzine review of the Nikon D810A highlights its specialized 36.3-megapixel sensor and enhanced infrared/hydrogen-alpha sensitivity, offering superior astrophotography performance with 1-to-2-stop noise improvement over the standard D810. Key pros include exceptional image quality, 5fps shooting, long-exposure modes up to 900 seconds (M*), and a robust, weather-sealed body with 1,200-shot battery life. However, the camera suffers from slow live view autofocus and lacks illuminated buttons, which limits ease of use in the dark, according to the review. Furthermore, the specialized sensor, which limits native ISO range, requires high-quality lenses to avoid resolution bottlenecks and can produce unnatural color balances in standard daylight, making it a niche tool rather than a general-purpose camera.

The Nikon D810A, an astrophotography-optimised variant of the D810, delivers unique advantages for everyday photography—particularly for wildlife and landscape shooters. Its sensor is finely tuned to the red wavelength, allowing it to naturally capture rich, accurate red and pink sunset hues that typically get distorted into yellowish-orange tones on standard camera RAW files. Furthermore, because its base sensitivity starts at ISO 200 rather than ISO 64, it yields exceptionally clean, low-noise files at higher ISO settings. Combined with its 36-megapixel high-resolution sensor and an incredibly quiet shutter click, the reviewer considers it an outstanding choice for animal photography. However, these specialized modifications introduce specific drawbacks for general use. The most prominent con is the higher €900 price premium over the standard D810. Additionally, the lack of a native ISO 64 or 100 makes achieving slow shutter speeds for moving landscapes or water difficult without purchasing extra neutral density (ND) filters. There is also a noticeable color-shift issue where standard green environments—such as a dim forest on a cloudy day—frequently take on an unwanted purple cast, forcing photographers to heavily rely...
