Nikon has today announced the launch of the first digital SLR format FX, specifically designed for astrophotography. The technology, dubbed Nikon D810A, based on the model Nikon D810.
D810A sensor type CMOS 36.3 megapixel resolution has no smoothing low-pass optical filter. In addition, an optical filter optimized for transmission of radiation of the spectral line H-alpha Balmer (wavelength – 656.3 nm) is observed in the spectra of most object space. Compared with the filter sensor camera D810, D810A sensors filter four times clearer for this part of the spectrum.
New color filter optimization for astrophotography not limited. In the list of profiles added manually select a long exposure (M *), where you can set the shutter speed to 900 s, and the preview function helps focus and framing, featuring an image corresponding shutter speed 30 seconds, if you select the shutter speed. Valve with electronic front shutter (in preview mode the mirror is raised) to minimize camera shake. In the viewfinder, you can include a permanent display of the virtual horizon that is displayed in red. By the way, as in the model D810, the image in Live View mode can be increased 23-fold to more accurate focusing, and the standard sensitivity range ISO 200-12800 expandable to ISO 51200 equivalent.
The camera is designed for continuous shooting. Full-time on a single charge Battery EN-EL15 can be made up to 3860 shots. Additional universal battery pack Nikon MB-D12 allows you to make up to 10,660 images. You can use the AC Adapter EH-5b.
The rest of the camera is not different from the D810. It also uses a system of controlling the parameters of the image Picture Control 2.0, the autofocus system Multi-CAM 3500FX 51-point system and metering with sensor RGB resolution of 91,000 points. Camera equipment includes a display size of 3.2 inches diagonally and flash.
Is a function of recording Full HD video at up to 60 f / s with the ability to change the sensitivity, shutter speed and aperture directly in the process of shooting. The camera is equipped with two slots for memory cards: CF (UDMA 7) and SD (SDXC, UHS-I). The camera body is made of magnesium alloy and is sealed to protect against dust and moisture.
With dimensions of 146 x 123 x 81,5 mm camera with battery and SD memory card weighs 980.
Sales Nikon D810A will begin in May for $ 3800. Recall, D810 at the time of issuance was valued at $ 3,300.
