Nikon D810A: Featuring a 36MP Sensor and an Infrared Filter
Nokia has recently released the D810A for the astrophotography enthusiasts, mainly targeting the aesthetic requirements rather than the scientific ones. The rollout might soon begin in May as we expect a higher-price tick for this specialized gadget. The specs sheet associated with this camera is detailed as follows:
Sensor and Lens
The D810A features a 36MP sensor which sports a fuller frame, paired along with an IR filter. This arrangement comes in as a modification to the existing D810 and is meant for astrophotography. While the usual filters are broad-ranging and easily filter out the visible radiation, the ones sported by the D810A are more sensitive to the longer wavelength in Red. The Hydrogen Alpha lines can be captured with ease as the emission nebulae is gauged closely for the hot hydrogen clouds and gases. The D810A might not be suitable for regular pictures and bound to bring in the reddish tinge.
The sensor size for the D810A featuring Nikon F lens is 35.9x24mm, featuring the CMOS make. The ISO rating for the same is 200-12800 with an expandable limit of up to 51200. The shutter speed range is 30-1/8000 seconds.
Self Timer is supported besides burst shooting rate of 5 frames per second.
Modes and Image Quality
Besides these, the multiple metering modes are also supported in Multi, Spot, Center-Weighted and many more. The D810A also supports several auto focus modes in Phase Detect and Live view besides supporting manual focus as well. The main highlight has to be the Long Exposure Manual Mode allowing one to set the shutter speed before setting up the Bulb Mode. The shutter speed limit which can be configured is 4 to 900 seconds in a time span of 15 minutes.
Another exciting feature has to be image monitoring option up to 23X for checking the focus accuracy. Again the Live view mode allows an exposure time span of 30 seconds which is certainly a generous limit for astrophotography. The electronic shutter is also present which reduces the mechanical shaking. The D810A comes with built-in Capture NX-D software for minimizing the image noises as well.
HD or 720p and 1080p video recording option is also supported by the D810A in addition to the multiple supported formats in MPEG-4 and H.264.
The D810A features a 3.2 inch TFT-LCD display with RGBW compatibility. The Optical viewfinder also comes in handy.
In terms of Connectivity, the D810A features only the USB 3.0 for high speed file transfers.
Dimension and Battery
In terms of physicality the D810A measures 146mmx123mmx82mm and weighs 880g. The entire body is structured out of magnesium alloy. The D810A sports the Nikon EXPEED 4 image processing chip which offers several selective flash modes to select from. Again the durable body is properly sealed against moisture and dirt. Powering the gadget is an EN-EL15 lithium-ion battery. Other exciting features include 51 autofocus points besides several flash modes in front-curtain sync and red eye reduction.
