Buried inside the camera are the heart and soul components of the D750. With the lens off, you can see the 24.3-Megapixel, full-frame FX-Format CMOS imaging sensor hiding behind the mirror. The sensor collects the light data for your images. Its light sensitivity ranges from ISO 100 to 12,800 natively, but is expandable to 51,200, along with a Lo1 setting that's equivalent to ISO 50. The sensor is complimented by the 51-point metering system and the 3D Color Matrix Metering III with a 91,000-pixel RGB sensor that produces fast and accurate exposures with crisp autofocus.
The brains of the camera is the EXPEED 4 image processor, which provides all of the power to the sensor, AF and metering systems and all other in-camera functions and shooting modes. It is also responsible for the fast frame rates, low noise levels and wonderful full 1080p HD video recording.
A final new addition to the D750 is the built-in WiFi system, allowing you to connect your smartphone or tablet to the camera without the need for an external adapter. You never have to worry about leaving the adapter behind allowing you to always have access to view your images on a separate device or to use it as a remote for the camera. It also allows you to share your images with the world anywhere you have internet access.
Above is the D750 with 24-120mm f/4 VR lens attached. This lens is available as one of the kit buying options and is currently available for approx. $3,600 directly from Nikon. The body is also available on its own for $2,300.
Here is a great example of the small body size of the D750 (compared to other full-frame DSLRs) along side the 24-120mm f/4 VR and 20mm f/1.8 lenses.
While they are not always included on dSLR's in this range, Nikon has included a small but powerful pop-up unit, with a range of up to 39ft. at ISO 100. This pop-up unit also works to control external flash units in the commander mode.
Composing your images is accomplished with the Eye-level Pentaprism viewfinder with built-in dioptic adjustment. It features 100% frame coverage with the FX-format image sensor. Camera information and AF is shown with a Type B BriteView Clear Matte Mark III screen, so you always know your shooting info.
On top is the camera's accessory hotshoe. This allows you to mount external accessories like an external SpeedLite or Video light.
Another new addition to Nikon's upper-level dSLR's is the 3.2-inch tilting LCD screen. With 1,229k dots of resolution and adjustable levels of brightness, the image details are easy to see in all lighting conditions. The screen is also used for all video and Live View shooting. Live View allows you to shoot at difficult angles with the tilting screen instead of just snapping and praying.
For storing your images, Nikon has included dual SD/SDHC/SDXC memory card slots. Dual high-speed cards allow for several recording options, including leaving the second card as overflow, separate cards for JPEG/RAW or still images and video. The camera is shown here with the SanDisk Extreme UHS-1 memory card that was used in all of our tests.
On the left side of the camera you will find all of the input/output ports. From top to bottom you will find the Remote Release port, headphone and microphone ports, and from left to right on the bottom are the high-speed USB and HDMI ports. This provides everything you need for both creative still and video inputs as well as being able to view them on any HDTV or external monitor with an optional HDMI cable.
