24.3MP FX-Format CMOS Sensor and EXPEED 4 Image Processor
The 24.3MP FX-format CMOS sensor works in close collaboration with the EXPEED 4 image processor to produce rich image quality accentuated by low noise and notable sensitivity to a native ISO 12800, which is further expandable to ISO 51200. The sensor and processor combination further work together to realize a wealth of speed throughout the camera system, including a full-resolution continuous shooting rate of 6.5 fps and full HD 1080p/60 video recording. The sensor can also record imagery in DX format and will automatically switch to and support the use of DX-dedicated lenses when attached.
51-Point Advanced Multi-CAM 3500FX II AF Sensor
Supporting the exceptional imaging capabilities of the D750 is an apt autofocus system that employs up to 51 distinct points, with options available to use 9, 21, or all 51 points depending on the situation, with AF detection sensitivity down to -3 EV. 15 cross-type points are also integrated within this array to provide even greater accuracy to centrally-located subjects. Benefitting the use of telephoto lenses and teleconverters, 11 of the focus points are also sensitive down to an aperture value of f/8. 3D Tracking, a part of the intelligent Scene Recognition System, also works to benefit maintained focusing on moving subjects for greater accuracy when shooting at high continuous shooting speeds.For even faster initial focusing and subject recognition, five AF sensors can be used together as a single focus point with the Group Area AF setting. Furthermore, Single-point AF, Dynamic-area AF (with 9, 21, or 51 points selectable), 3D-tracking (using all 51 points), and Auto-area AF modes are also available.
Scene Recognition System and Exposure Metering
The intelligent Scene Recognition System with 3D Color Matrix Metering III utilizes a 91,000-pixel RGB sensor to evaluate and analyze all aspects within a scene, including brightness, contrast, subject distance, and the scene colors, to quickly determine an accurate exposure and white balance setting to best render the scene at hand. The information gathered is also checked against onboard reference images to ensure consistency from image to image in regard to exposure, white balance, i-TTL flash settings, and subject-tracking AF performance. Additionally, benefitting working in difficult lighting conditions, a highlight-weighted metering setting can be used to maintain faithful highlight reproduction.
Built-In Wi-Fi Connectivity
Supporting a wealth of sharing and tagging possibilities, the D750 features built-in Wi-Fi connectivity to enable seamless transfer of imagery as well as remote shooting capabilities. Once the Nikon Wireless Mobile Utility app has been installed on an Android or iOS mobile device, you can use that device to browse the contents of the memory card, select images, and seamlessly transfer files between devices for immediate sharing online. Additionally, the mobile device can remotely trigger the shutter and display a live view image from the camera to enable working from a distance.
