From Nikon: The D810A Provides New Features Specifically for Astrophotography, Nikon Also Announces Availability of D750 Filmmaker’s Kit
MELVILLE, NY – Today, Nikon Inc. announced the new D810A, a DSLR optimized for astrophotography and other scientific applications. By modifying the infrared cut filter for the hydrogen alpha wavelength, Nikon has created a camera that gives photographers the ability to capture the diffuse nebulae in the night sky and to create colorful, breathtaking celestial images. The D810A shares its architecture with the powerful and professional high-resolution Nikon D810 DSLR and includes other new features designed uniquely to help capture the cosmos, letting users achieve sharp and vibrant images of the universe.
“The Nikon D810A is engineered exclusively to meet the unique demands of professional and hobbyist astrophotographers,” said Masahiro Horie, Director of Marketing and Planning, Nikon Inc. “The camera’s distinctive feature set and powerful imaging capabilities make it an appealing option for those who are ready to discover the fantastic cosmic features that are hidden among the stars.” I AM Star Struck: DSLR Optimized for Astrophotography
The Nikon D810A provides hobbyists as well as professional stargazers with a powerful combination of impressive resolution and features specifically created for astrophotography and scientific applications. The infrared (IR) cut filter has been optimized to allow transmission of the hydrogen alpha spectral line, resulting in four times greater sensitivity of the 656nm wavelength. The resulting images capture the brilliant red hues of diffuse nebulae and constellations in striking detail and fidelity. While not recommended for general photography, the D810A is an excellent option for photographing the universe with either NIKKOR lenses or third-party adaptors for telescopes.
In addition to the optimized IR cut filter, the D810A adds other features that are useful for astrophotography applications. A new Long Exposure Manual Mode is implemented, giving users the ability to set shutter speeds from 4, 5, 8, 10, 15, 20, 30, 60, 120, 180, 240, 300, 600 or 900 seconds (15 minutes), as well as Bulb and Time settings. Building upon the D810’s excellent low-light capabilities, the ISO range has been optimized from 200 to 12,800 (Hi-2 51,200), for maximum sensitivity with the optimal signal to noise ratio.
The D810A also adds a new Virtual Exposure Preview Mode, which displays an estimated preview image and is available when shooting at shutter speeds longer than 30 seconds when in Live View. The brightened preview image represents a 30 second exposure, simplifying focusing and composition. The Best of Both Worlds
The Nikon D810A is based off of the Nikon D810 architecture and retains all of the features that make it a powerful tool for creating images. Users will be able to produce photos of the heavens in super high resolution thanks to the 36.3-megapixel CMOS sensor. The image sensor works in tandem with Nikon’s exclusive EXPEED 4 Image processing engine to deliver images with low noise and a dynamic range that is nothing short of stellar. The D810A also features an Electronic Front Curtain Shutter Mode, letting the electronic front curtain act as a shutter when in live view or first composing through the optical viewfinder in mirror-up mode. This feature minimizes vibrations to attain maximum sharpness when shooting subjects at very slow shutter speeds. The camera also features a durable magnesium alloy body that is sealed against dirt and moisture, giving users peace of mind when getting away from the city lights means a trek off of the beaten path.
The Nikon D810A is compatible with a wide range of high quality NIKKOR lenses and accessories, including wireless infrared remotes, cable releases and the new WR-1 wireless remote system. Additionally, Nikon’s Capture NX-D software is available as a free download, and it will feature a new option for Astro Noise Reduction for use with D810A image files. Nikon D750 Filmmaker’s Kit
For users who are looking to take advantage of the Nikon D750’s advanced video capabilities, Nikon is now offering a Filmmaker’s Kit that includes everything needed to get started in the world of cinema. The kit contains three NIKKOR lenses in popular focal lengths, including the AF-S NIKKOR 35mm f/1.8G ED lens, the AF-S NIKKOR 85mm f/1.8G lens and the AF-S NIKKOR 50mm f/1.8G lens; all which provide stunning HD clarity and excellent depth of field control for filmmakers. The kit also contains two additional EN-EL15 batteries, an ME-1 Stereo Microphone, one Atomos Ninja-2 External Recorder, and Tiffen 67mm and 58mm Variable Neutral Density Filters (8-Stops) for superior control of light. In addition, the Nikon D750 Filmmaker’s Kit features custom foam inserts, which are ideally sized for use in a hard case for transporting equipment to your next video production.

Sigma has just announced a lens that closely resembles another highly successful model in their lineup, the
Sigma 35mm f/1.4 DG HSM Art Lens
If these two lenses share similar image quality, the 24 Art is a certain hit.
Sigma Corporation of America Introduces New 24mm F1.4 DG HSM Art Lens at CP+ Imaging Show
Latest Global Vision Art lens offers highest-quality optical performance in its class
YOKOHAMA, Japan — February 10, 2015 – Sigma Corporation of America, a leading researcher, developer, manufacturer and service provider of some of the world's most impressive
lines of lenses, cameras and flashes, today announced the new Sigma 24mm F1.4 DG HSM Art lens,
the ninth Global Vision lens to join the company’s iconic Art line-up.
The announcement comes at the start of the CP+ Camera and Photo Imaging Show 2015, which begins on Feb. 12 in Yokohama, Japan.
The much anticipated 24mm F1.4 Art wide angle lens is designed for full-frame DSLRs, and when used on digital cameras with an APS-C size image sensor,
it effectively becomes a 38mm.
The lens is ideal for capturing a variety of photography subjects, including cityscapes, mountain ranges, astrophotography and weddings and is great for videography work as well.
The 24mm also excels at indoor photography in low illumination thanks to the combination of exceptional focal plane sharpness, and gorgeous bokeh rendered by nine rounded aperture blades.
The lens achieves a maximum magnification of 1:5.3 with a minimum focusing distance of 9.8 inches.
The 24mm incorporates both "F" Low Dispersion (FLD) glass and Special Low Dispersion (SLD) glass in a design of 15 elements in 11 groups to minimize chromatic aberration
of magnification especially in the edge of the image field.
Moreover, the optimized power layout includes aspherical elements that are positioned in the rear of the lens for improved wide open performance.
This helps to ensure minimal distortion through the correction of axial chromatic aberration and sagittal coma flare.
The new lens element design also delivers excellent peripheral brightness.
“The Sigma Art lenses are recognized by photographers for world-class performance, and the new 24mm F1.4 DG HSM will be a significant contribution to our selection of fast aperture prime lenses which is quickly becoming a strong force in the industry” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “Sigma is redefining the expectations of fast-aperture full-frame prime lens performance, especially wide-open, and the results the 24mm F1.4 will deliver will be up to the exacting standards set by the 35mm F1.4 DG HSM and 50mm F1.4 DG HSM .”
Other updates to this lens include a new full-time manual focusing mechanism that switches to manual focusing, simply by rotating the focus ring, even when AF is being used, first introduced on the 50mm Art. This allows the photographer to make focus adjustments quickly and easily. As with all new lenses under the Global Vision categories, every 24mm will be tested using Sigma’s own MTF measuring system, “A1,” in the company’s factory in Japan.
Other lenses in the Art line include
35mm F1.4 DG HSM
30mm F1.4 DC HSM
18-35mm F1.8 DC HSM
24-105mm F4 DG OS HSM
50mm F1.4 DG HSM
19mm F2.8 DN, 30mm F2.8 DN and 60mm F2.8 DN.
The 24mm F1.4 is compatible with Sigma’s USB dock
, allowing photographers to update the lens’ firmware and change focus parameters as well as manual focus over-ride using Sigma's Optimization Pro software. It is also compatible with Sigma’s Mount Conversion Service. The lens will be available in Canon, Nikon and Sigma mounts, and timing, pricing and availability will be announced at a later date.
Ordering the Sigma 24 Art Lens
Hopefully the fulfillment process for this lens is more expediant than we are currently experiencing with the 150-600 Sports and 24-105 Art lenses.
While many lenses are introduced to relatively low demand, my expectation is that this is not one of them.
Sigma 24mm f/1.4 DG HSM Art Lens
mounts on their site, but preorders are not currently being accepted.
