The full-frame 36.3-megapixel Nikon D810A is engineered exclusively for astrophotography to capture magnificent images of nebulae that emit on the hydrogen-alpha wavelength. Thanks to a redesigned infrared (IR) cut filter, the D810A is four times more sensitive to the H-alpha spectral line (a wavelength of approx. 656 nm) than the Nikon D810. A powerful tool for photographers, this specialised DSLR frees you to capture the true colour of deep sky marvels without modifying the camera.

Durable magnesium alloy body
Extensive weather and dust sealing ensure the D810A is moisture and dust resistant.

High-resolution FX-format astrophotography
Capture nebulae that emit on the hydrogen-alpha spectral line (approx. 656 nm) with incredible clarity.

Modified Infrared (IR) cut filter
Capture nebulae and starfields without external filters. The D810A transmits light from the hydrogen-alpha spectral line at a rate that is four times higher than the D810.

Outstanding resolving power
Unleash the power of 36.3 effective megapixels. The FX-format sensor delivers spectacular high-contrast images with minimised false colour.

Long exposure M mode
Alongside Bulb and Time settings, a dedicated Long Exposure manual mode allows exposures of up to 900 seconds.

Electronic front-curtain shutter
Activate the electronic front-curtain shutter to minimise internal vibrations during exposure and reduce the risk of micro-blur in even subtle details.

Spectacular ISO
The D810A’s standard ISO range of 200—12800 can be extended up to 51200 ISO (equivalent). Nikon’s 3D noise reduction enables clean, well-defined images at high ISOs.

EXPEED 4
Boosts the camera’s overall performance. Vastly improves image rendering and ISO performance, and minimises colour fringing.

Unlimited continuous shooting
Produce seamless star-trail photography. Shoot in continuous release mode with a shutter speed of 4 seconds or slower, and you can record as many high-quality JPEGs as your media cards and battery life allow.

Extended shooting
Reliably capture thousands of images with long exposures. The D810A’s energy efficient design and high-capacity battery will keep you shooting for long periods. Optional Nikon battery packs and power adapters can extend shooting time immensely.

Multi-CAM 3500FX 51-point AF system
Fine-tuned for ultra-high resolution images. Configurable in 9-point, 21-point, and 51-point coverage settings and sensitive down to -2 EV (ISO 100, 20 °C/68 °F). System benefits include Group-area AF, expanded “store by orientation”, and options for AF mode restrictions. Fifteen cross-type sensors in the centre are compatible with AF NIKKOR lenses with open aperture of f/5.6 or faster, and 11 central focus points work with an open aperture of f/8.

Fast, durable, responsive
The D810A starts up in approximately 0.12 seconds and boasts a shutter release lag of just 52 ms. The Kevlar/carbon fiber–composite shutter unit is tested to 200,000 releases and offers shutter speed of 1/8000 to 900 s.

Live view
Increase the Live view image up to 23x and make critical focus checks with absolute precision. A virtual exposure preview for bulb and time settings also aids focus and framing.

Red-lit virtual horizon
A red-lit virtual horizon display lets you confirm leveling when shooting through the viewfinder.

Colour-tune monitor
Push the colour balance and brightness in any direction to suit your personal workflow preference. The anti-reflective 8.0-cm (3.2-in.), 1229k-dot RGBW LCD monitor also offers auto brightness control.

Picture Control 2.0
Take complete control over sharpening, contrast, brightness, hue, and saturation when shooting stills and video. Shoot with the Flat setting for the ultimate freedom in postproduction: retain all the details and preserve rich tonal information in both highlights and shadows. Use the Clarity setting to precisely adjust contrast and differentiate fine structures.
