Nikon D810A Digital SLR Camera Body Only

Product Code: 3010365R
The Nikon D810A is a full-frame DSLR designed especially for astrophotography. This camera features a range of specialised functions so you can capture some fantastic images of the night sky.
RRP £3,299.00 £2,679.00   after £0.00 cashback.


The Nikon D810A is a specially modified version of the popular D810, and is designed to shoot spectacular high-resolution images of the night sky.

Within the D810A, there is a redesigned infrared cut filter which is more sensitive to the H-alpha spectral line. This means that the true colour of nebulae that emit on the hydrogen-alpha wavelength can be captured on the 36.3 megapixel FX-format sensor, without the need to modify the camera. Working alongside the new filter, the camera’s ultra-high ISO, outstanding resolving power, and a host of specialised functions combine to ensure photographers can capture deep sky marvels in brilliant detail.

The D810A has also been designed to counteract some of the challenges faced when shooting into the night sky. Alongside Bulb and Time settings, you’ll find a new Long Exposure Manual mode that allows exposures up to 900 seconds. When shooting in Live View, to aid focussing and framing, a virtual exposure preview will be shown, and when you’re using the viewfinder, a red-lit horizon will appear to help confirm you are level.

Full Details


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.

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.

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.

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

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.

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.

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.

Multi-area D-Movie
For high definition video footage of the cosmos. The D810A records Full HD (1080p) movies in FX and DX formats at 50p/60p frame rates with markedly reduced moiré and false colour. Nikon’s 3D noise reduction reduces random noise, distortion, and flicker when filming at high sensitivities. The camera offers clean HDMI out, plus simultaneous capture of full-resolution footage in-camera and on an external recorder.

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.

NIKKOR lenses
Draw out the full potential of the D810A’s 36.3-MP sensor with the wide range of NIKKOR lenses. With their exceptionally high resolving power, NIKKOR lenses are acclaimed by astrophotography enthusiasts worldwide.

High-capacity EN-EL15 battery
Ultra-compact and lightweight lithium-ion rechargeable battery with a capacity of 1900 mAh (7.0 V). Capture up to 3,860 still images* on a single charge.

Additional power sources
Optional Nikon accessories keep you shooting for longer. The MB-D12 Multi-Power Battery Pack works seamlessly with the camera and can capture up to 10,660 still images on a single charge.** The sequence of battery use can be selected and set via the camera. To extend shooting time further, use the optional EH-5b AC Adapter with the EP-5B Power Connector.

Storage media
Two card slots for a smooth shooting experience. One CF card slot for high-speed UDMA 7 cards, and one SD card slot for high-speed, high-capacity SDXC and UHS-I cards.

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

Wired and wireless connection
The D810A supports Ethernet and wireless LAN. To connect, use the optional UT-1 Data Transmitter together with the WT-5 Wireless Transmitter.

*Based on Nikon tests where the built-in flash was not used, and images were not played back. According to CIPA standards, approximately 1,200 images can be captured on a single charge with the built-in flash fired for half of the exposures.

**Based on Nikon tests without using a built-in flash. Based on CIPA standards, approx. 3,270 images are captured with a built-in flash fired for half of exposures.
