First Nikon D5 and more D810a details leaked

The first rumors about the Nikon D5 have appeared on the web, suggesting that the flagship FX DSLR will be revealed sometime later this year with a new image sensor.

At the beginning of 2014, Nikon announced the development of the D4s, its flagship professional camera that would take the place of the D4. The DSLR was released sometime in March 2014. Although higher-end models usually have a slower refresh cycle, it seems like the Japan-based company will launch another flagship FX DSLR by the end of the year.

An unnamed source is reporting that Nikon will introduce the so-called D5 during the second half of this year, while revealing some details about the camera.

Nikon D4s might be replaced by the Nikon D5 in 2H 2015.

Nikon D5 rumored to be announced during the second half of 2015

The Nikon D5 DSLR camera is rumored to employ a brand new 20-megapixel full frame image sensor, which will be an upgrade over the 16.4-megapixel sensor of the D4s.

Additionally, the shooter will come packed with a 173-point autofocus system, which will be a significant improvement over the 51-point AF system offered by the current flagship.

Nevertheless, the design and the body size will be “similar” to the ones of the D4s. For now, the source is inviting photographers not to expect any drastic changes in the design.

Last, it appears that the D5 will be powered by the same EXPEED 4 image processor as the D4s.

As usual, this information needs to be taken with a pinch of salt, especially considering the fact that the Nikon D5 is expected to be announced in 2H 2015.

Nikon D810a, the astrophotography version of the D810, coming soon

During the first few days of February 2015, a source claimed that Nikon was working on a special version of the D810. This DSLR would be aimed at astrophotographers as it would offer a higher hydrogen-alpha sensitivity.

Hydrogen-alpha is a spectral line that corresponds to deep-red color in the Balmer series. It appears when a hydrogen electron gets from its third lowest energy level to its second lowest level. Among others, nebulae emit such light, so it is important in astrophotography.

Canon has previously launched the EOS 60Da, which is based on the EOS 60D, but comes with a higher hydrogen-alpha sensitivity than the regular model.

The new Nikon D810a rumors are stating that the camera will offer a longer shutter speed. It is said that five more stops of shutter speed will be offered by the astrophotography-aimed DSLR.

Its announcement is said to take place this week, before the beginning of CP+ 2015. Stay tuned for more information!
