Nikon has just announced its newest flagship DX-format DSLR: the D7100. This professional-grade camera with APS-C-sized sensor is the successor to the deservedly popular D7000, and improves upon it by way of increased speed, imaging performance and connectivity options. As a DX-format camera, the D7100’s aim is to blend high image quality elegantly with a compact form factor that makes it ideal for use in fast-paced working environments.
24.1MP DX CMOS Sensor and EXPEED 3 Image Processor
Improving upon the D7000’s image-sensor-and-processor combination, the D7100 integrates a 24.1 megapixel DX CMOS sensor and EXPEED 3 image processor. These two technologies work in tandem to produce high-resolution imagery with immense detail and clarity. In regard to the image sensor, the most significant change, compared to other DX-format cameras, is the removal of the optical low-pass filter. By removing this filter in front of the image sensor, greater image sharpness, detail and resolution are afforded for producing stills and movies with truly rich overall quality and vibrancy. The image processor, which is the same used in the FX-format D4 and D800 cameras, lends itself to efficient processing and noise reduction capabilities, and works to produce a native sensitivity range of ISO 100-6400, which can be further expanded to ISO 25600. The processor also contributes to all-around speed throughout the camera, notably in regard to a full resolution continuous shooting rate of 6 fps for up to 100 frames, which can be increased to 7 fps when working in the new 1.3x DX crop mode.
51-Point Autofocus System and 2,016-Pixel RGB Sensor
Significantly benefitting the imaging power of the sensor and processor is a refined Multi-CAM 3500DX autofocus sensor that utilizes 51 focus points to effectively blanket the scene in order to achieve sharp focus in a quick manner. The breadth of the focus areas also greatly aids shooting fast-moving subjects and maintaining focus while shooting in continuous modes. These 51 focus points include 15 cross-type sensors for greater detection of both horizontal and vertical contrast variations, which in turn produce both faster and more accurate focusing capabilities. Additionally, a central cross-type sensor is capable of working down to f/8.0 to support critical focusing with longer lenses and teleconverters.
For precise exposure metering, a 2,016-pixel RGB sensor works to evaluate different aspects of each scene, including contrast, subject distance and color, for intelligently determining accurate exposure settings. The exposure metering system works in collaboration with the autofocus system to provide face priority and subject tracking abilities in order to maintain consistent results while shooting. Nikon’s Scene Recognition System can also be employed to analyze the scene in order to determine white balance, exposure and iTTL flash settings for further consistency throughout one’s workflow.
With the introduction of the D7100 also comes a newly developed white balance system for intuitively customizing and setting white balance and color-temperature profiles. Spot White Balance can be used when working in Live View mode and provides an adjustable spot for selecting a small portion of the image from which to adjust the camera’s white balance setting; this feature will allow fast and efficient color profiling abilities while working. Also available are Picture Control mode, which allows a greater access to viewing and modifying the color characteristics of images, and Auto HDR, which composites simultaneously exposed frames into a single frame to produce an image with greater highlight and shadow detail. For creative enhancement of images, different Image Effects can be applied to both stills and movies in real time, with the results visible when monitoring in live view.
Camera Body Design
The D7100 balances its professional imaging features with an equally high-quality construction and form factor that is well suited to professional usage. The body design incorporates magnesium alloy top and rear covers to add durability and rigidity to the camera, yet the D7100 still remains lighter than its predecessor. The inclusion of durable construction materials also enables greater weather and dust resistance for increased protection when working in outdoor or adverse conditions. In line with many other professional-grade cameras, dual SD, UHS-I-compatible memory card slots are available to increase the recording abilities and provide an array of options for saving image files in order to expedite the post-production workflow.
For live view monitoring, image playback and review, and menu navigation, a large 3.2" 1,229k-dot LCD monitor is available and features an RGBW color scheme for greater overall brightness and visibility. Additionally, an optical glass pentaprism viewfinder is available and provides 100% frame coverage. The viewfinder incorporates a low-power-consumption OLED display element for clearly highlighting exposure and camera information within the finder.
The built-in pop-up flash is available to simply provide additional illumination to scenes; however, it can also function as a wireless flash commander when used in connection with iTTL-compatible speedlights. It also supports use of Nikon’s Advanced Wireless Lighting system to give more control over lighting ratios and other flash controls when working with multiple wireless flash units.
Full HD Movie Recording
The D7100 supports full HD 1920 x 1080 video recording in multiple frame rates, including 60i, 50i, 30p, 25p and 24p for a range of control over the appearance of movies. HD 1280 x 720 recording is also available in frame rates up to 60p for fluid rendition of movement. When recording movies, full-time continuous autofocus is available, as is manual exposure control for the ability to easily modify overall brightness values as well as depth of field. The built-in stereo microphone can be used for recording sound with movies or, alternatively, an external stereo microphone jack is also available for greater control over recorded sound. A headphone jack is also built in to permit real-time monitoring of audio when recording movies. The HDMI output allows for the use of an external monitor or for direct viewing of recordings on an HDTV.
Full wireless connectivity is possible with the D7100 when paired with the optional WU-1a Wireless Mobile Adapter. When connected, this adapter provides the ability to instantly share images and movies directly to an iOS or Android mobile device for sharing to social network or image-hosting sites or for simply emailing or texting. When used in connection with Nikon’s Wireless Mobile Utility app, the mobile device can also serve as a remote controller and live view monitor for the camera.
18-105mm f/3.5-5.6 Lens Kit
In addition, the D7100 being available as a body only, it is also available in a kit with the AF-S DX NIKKOR 18-105mm f/3.5-5.6G ED VR lens. This lens is ideal for shooting in a wide variety of conditions, as its 35mm-equivalent focal length range is 27-157.5mm, covering wide-angle to telephoto perspectives. Nikon VR (Vibration Reduction) image stabilization works to reduce the appearance of camera shake by up to three shutter-speed steps, resulting in sharper imagery when working in low-light conditions and with longer zoom magnifications. A Silent Wave Motor focus system provides quiet and accurate focusing abilities and the inclusion of one ED (extra-low dispersion) glass element helps to reduce chromatic aberrations and improve overall image sharpness.
The D7100 stands to be a significant advancement in regard to the professional-grade DX-format DSLR. As a flagship model, it includes the necessary improvements relating to imaging performance, without neglecting the main features relating to speed and portability that make the DX-format so enticing. The redefined shooting and connectivity features of the D7100 favor all users, as their benefits work in collaboration to result in a camera that is highly efficient, capable and enjoyable to use.
