Nikon D4

Nikon D4 New Flagship in the sock of the Epiphany



 The stocking of the Epiphany nikonisti find a big surprise, the latest jewel professional expectation Nikon D4, full frame SLR designed for quick snapshots and record video in Full HD.
For fotograf professionals (and enthusiasts with a nice budget available) that i always want the best Nikon camera offers an "important" - 160 x 157 x 91 mm and a weight of 1340 grams for the body only - with a sensor CMOS FX (full frame format) from 16.2 megapixels and Nikon's EXPEED image processor 3.

Exceptional Image Quality and Speed

The Nikon D4 is designed to ensure the highest quality images in most lighting conditions. Noise minimized, signal processing A / D 14-bit built-in sensor and wide dynamic range even at high ISO settings.
The ISO range sets a new reference to ISO 12800 and shifts the interval to take an additional EV ISO 100 as standard. In the most extreme shooting situations, you can have sensitivity levels between 50 and ISO 204800.

The power of the processor EXPEED 3 allows the Nikon D4 to speed even those complex operations that need to handle large amounts of data. After the A / D conversion 14 bit image processing 16-bit high-speed allows you to export JPEG ready for presentation directly from the camera.
The EXPEED procssore 3 and the sensor FX channels allow browsing of the Nikon D4 to reach the maximum speed of shooting 11 frames per second. And with this new standard in terms of silence.

The startup time is about 0.12 seconds, the shutter lag of about 0,042 seconds (equivalent to those of the Nikon D3S).
The shutter in composite materials (Kevlar and carbon fiber) is a new concept. Nikon offers a standard life cycle of 400,000 shots. The maximum shutter speed ranges from 1/8000 to 30 seconds, with flash sync up to 1/250 seconds.
Of note is the intelligent monitoring for self-diagnostic shutter control unit to reduce power consumption when the shutter is raised for long periods of time while recording movies.





 Professional HD Video

Although not all professional photographers need to shoot video, a professional camera today can not refrain from offering super performance in this area. So the Nikon D4 records video in Full HD (1080p) at 30p, 25p and 24p, with 60p options, 50p, 30p and 25p to 720p. The video length is about 29.59 minutes.

Multi-area modes: allows recording in Full HD (1080p) and FX DX format, as well as in reduced format native Full HD (1920x1080).

High-fidelity audio control: the D4 offers the external stereo microphone input and audio output for external headphones which optimizes the audio for recording movies with an excellent sound insulation.

Uncompressed HDMI output - for those who need the best result for a video editing professional quality, the D4 offers the possibility to export the video in Live View mode uncompressed recorders and external monitors. It is the first time that this operation is possible in a SLR camera. The data are extracted to 1080i (Full HD) with the image size and frame rate indicated. If necessary, the data output can be scaled without the overlap of information, but can be simultaneously displayed on the TFT monitor camera.

Autofocus system Rirpogettato

Nikon has also worked on the autofocus system, improved both on speed and on that of precision.
The sensor module Multi-CAM 3500FX AF has been redesigned to improve the rapid detection of the subject. It offers coverage settings to 9, 21 and 51 points, individually selectable or configurable, has been redesigned to improve the speed of detection of the subject.

The module and the algorithms of the sensor autofocus significantly improve the sensitivity of the acquisition in low light conditions down to -2 EV (ISO 100, 20 ° C). All 51 AF sensors, 15 of which are cross-type sensors, are extremely reactive with any NIKKOR AF f/5.6 and, for the first time, this performance is not limited to the openings f/5.6.

The D4 maintains the full power of 11 AF sensors central, even if the aperture value is combined f / 8. A great help if you take pictures or sporting nature, because it achieves a new level of detection by combining, for example, a NIKKOR AF 600 mm f / 4 and a NIKKOR 2.0x multiplier. If the combined aperture is between f/5.6 and f / 8, you can harness the power of 15 central AF sensor.

The Nikon D4 is the first reflex with the support for the new memory cards XQD: There are two slots, one for CF cards (UDMA 7) and one for the tabs XQD.

Connectivity: a powerful system for monitoring and reporting of data makes it quick and easy file transfers over the LAN cable and wireless. The wireless LAN support is available with the new Wireless Transmitter WT-5 Compact, HTTP and FTP connection, and allows for the simultaneous release of multiple cameras with WT-5 system. For the first time in the camera is integrated wired LAN connection.
