The Nikon D810A is the first full-frame FX format digital SLR designed for astrophotography and other scientific applications. Sitting proudly in a class of its own, the D810A brings a 36.3-megapixel CMOS sensor and a redesigned infrared (IR) cut filter that's four times more sensitive to the H-alpha spectral line to allow breathtaking celestial images of nebulae to be captured in all its natural and colourful beauty.

Nikon Video: The World of Astrophotography
As a modified version of the camera that boasts the most outstanding resolving power of any Nikon D-SLR, the D810A is a very special beast. Designed to deliver the ultimate in image detail, the FX-format sensor enables high-contrast 36.3-megapixel images with minimised false colour. The standard ISO range of 200-12800 can be extended up to 51200 ISO (equivalent) and 3D noise reduction enables clean, well-defined images at high ISOs. Nikon’s fast and powerful EXPEED 4 image processor boosts the camera’s overall performance and minimises colour fringing.
Modified infrared (IR) cut filter
A truly exceptional camera, the D810A delivers results that are impossible to achieve with a regular D-SLR. The D810 is a popular camera with astrophotographers: it has the power to photograph the night sky, but a standard camera sensor is not the best way to capture images of nebulae that emit on the H-alpha wavelength. In order to prevent red colour cast, the optical filters in general D-SLRs restrict transmission of reddish light in the visible light range. In contrast, the characteristics of the D810A’s optical filter have been modified to increase the transmission of reddish light from the hydrogen-alpha spectral line by approximately four times (compared to the D810). As a result, photographers can now capture the beautiful, “true-red” colour of nebulae that emit along the H-alpha wavelength without modifying the camera. The benefits of the D810A’s modifications are apparent, even when photographing starfields and star landscapes.
Equipped with a number of specialised functions, the D810A effectively counters some of the challenges astrophotographers face. Alongside Bulb and Time settings, a new Long Exposure Manual mode allows exposures of up to 900 seconds. To minimise internal vibrations during exposure, photographers can activate the camera’s electronic front-curtain shutter and reduce the risk of micro-blur in even subtle details. When shooting in Live view, a virtual exposure preview for Bulb and Time settings aids focus and framing. And, as with the D810, the Live view image can be magnified up to 23x, allowing critical focus checks to be made with absolute precision. When shooting through the viewfinder, a new red-lit virtual horizon display lets you confirm leveling.
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.
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.
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.
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.
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.
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.
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.

Applicants must be:
- Aged 18 years or older from the application date
- In permanent UK residence for a minimum of three years
- Fulfil at least one of the following employment criteria:
- In regular, permanent employment.
- Retired from regular employment - With a minimum age of 50.
- Not working through disability.
Note: All applicants will be subject to a credit reference check by the lender.
Credit is subject to application and status. Warehouse Express Ltd trading as Wex Photographic act as credit broker and not the lender. Barclays Partner Finance act as the lender.
Can I repay early? If so how?
No repayments are scheduled in the initial six-month deferral period. However, it is possible to pay off the loan, either by way of a lump sum or in smaller amounts. If the loan is fully repaid within the six-month deferral period, then no interest is payable, but a £29.00 early-settlement will be incurred. Such repayments may be made to Barclays Partner Finance by cheque, debit card or standing order. Unfortunately it is not possible to set up a direct debit within the deferral period. Further information on how to make such repayments will be set out in the loan agreement pack provided by Barclays Partner Finance.
What happens if I don't repay within the first six months (deferral period)?
Following the six month deferral period, Barclays Partner Finance will initiate a monthly direct debit payment for the remaining duration of the loan. Interest will be charged at a rate of 19.9% APR on outstanding balances (backdated to the first date of the loan). Late payment penalties and early repayment charges will apply from this point. Barclays Partner Finance will send a reminder letter approximately one month before the six month deferral period is due to elapse. Note: If you chose to spread the cost and pay monthly, interest is charged from the start of the loan, not from the start of the repayment period.
What will I receive from the finance provider (lender)?
Barclays Partner Finance will send a loan agreement pack approximately four weeks after delivery of the goods, confirming that the account has been activated and, from this point, it is possible to make repayments against the loan.
