The D7100 is a 24-megapixel camera with an 18mm-105mm kit lens that has a 35mm-equivalent focal length range of 27mm-157.5mm. It has a 3.3-inch LCD (1,229,000 pixels). It also includes a through-the-lens viewfinder, which is helpful when composing in bright light.
Because it accepts interchangeable lenses, and includes a mirror and a through-the-lens viewfinder, we consider this model an SLR.
The camera's kit lens has a maximum aperture of f/3.5. The camera's shutter speed range is 30 seconds to 1/8000 of a second.
The D7100 stores photos and video on SD/SDHC/SDXC memory cards. It captures images as JPG or RAW files at a top resolution of 6000 x 4000 and full HD-resolution video as MOV files at a top resolution of 1920 x 1080 at 60p and 60i fps.
Like most digital cameras, this model comes with a proprietary rechargeable battery.
This SLR model has 51 autofocus points. It also includes 22 exposure modes, and an exposure compensation control that can be set at +/-5 EV. The image stabilization system for this camera is optical.
The D7100 measures 5.3 inches wide by 4.2 inches high by 3 inches deep, and weighs 44 ounces (2.7 pounds) (with battery, memory card, and strap).
Full frameA full-frame image sensor is the size of one frame of 35mm film and significantly larger than sensors found in many other digital cameras. Often, this type of sensor handles a wider variety of lighting situations more accurately. It also limits the amount of visual noise that can distort and degrade an image.
Swivelling screenA swivel screen allows you to frame difficult-angled photos in the camera’s LCD screen. It is also called an articulated display, which when used on a tripod allows you to tilt the LCD screen to avoid either having to stand on your toes or to crouch to the level of the LCD screen to be able to see it. A fully articulating screen allows you to shoot selfies and to see how it is framed when standing in front of the camera while shooting photos or video.
Hot shoeA hot shoe is located on top of the camera and is used to attach a flash unit and other compatible accessories. It is a bracket, which surrounds an electrical connection between camera and accessory for standard, brand-independent flash synchronization.
Memory cardMemory cards indicates the types of memory cards a model can accept if it has a built-in memory-card reader for playback of MP3 audio files or JPEG picture files.
Color spaceThis refers to computerized models of color ranges that a camera can reproduce. The two most common are sRGB and Adobe RGB. In terms of size, Adobe RGB has a larger color range than sRGB. Another model, ProPhoto RGB, has one of the largest ranges. Color spaces can generally be set via your SLR's menus.
PC flash sync jack
PC flash sync jackAlthough the hot shoe is the most common method, you can also use this terminal to connect your flash to your SLR body.
Maximum apertureThe maximum aperture (lens opening) for wide and telephoto shots. A single number indicates that the camera does not have a zoom lens.
Touch screenDisplay that is sensitive to finger contact, letting you select and move screen objects, launch programs, choose from menus, scroll through photo libraries, and the like. Some touchscreens have "multi-touch", letting you use more than one finger to resize and rotate objects.
Wireless remoteThe remote control included with the camera.
Widest angleThe lower the number for widest angle, the broader the vista the camera can capture.
Live viewThis feature lets you compose directly on the camera's LCD display.
Exposure modesThese modes or settings refer to those available directly on the main mode dial and often include the main exposure modes, such as program auto, shutter priority, aperture priority and manual. Select scene modes, such as portrait, sports, close-up and landscape modes as well as additional settings can be found on this dial as well.
Exposure compensationAllows for minor adjustments to the automatic-exposure settings. When a scene has high contrast, as in a backlit scene, automatic exposure may not achieve the effect you want. It helps to be able to alter the settings so that the subject of the photo does not appear too dark or too light.
Manual focusDigital cameras provide greater depth of field than cameras with longer focal-length lenses, such as 35 mm or APS cameras; therefore, manual focusing will rarely be needed. It's not even possible to do on some cameras. Manual focus options vary; a few cameras provide a continuously adjustable manual focus ring, others only a limited number of discrete focus distance settings.
Macro focusThis is a setting that allows you to take extreme close-ups, from a few inches to only 1 or 2 feet away from the subject. test
Manual controlsSome cameras allow the user to set the aperture (f-stop), shutter speed, or (usually) both. This feature is used to override the automatic exposure settings when more control is needed. During a sporting event for example, you may want to use a high shutter speed to freeze the action. Or, you may want to use a low shutter speed to blur moving objects (like a waterfall) while keeping stationary objects sharp. Using shallow depths of field can be used to blur the background of photos while keeping the foreground in focus. Typically up/down arrow keys are used to change settings displayed on the LCD or in the viewfinder. These controls are not as easy to use as on conventional film cameras.

35mm equivalent multiplier
35mm equivalent multiplierMany SLRs have sensors that are smaller than the actual size of one frame of 35mm film, which changes a lens's effective focal length. To determine the equivalent focal length, you multiply the lens's focal length by the appropriate multiplication factor. Most Nikon SLRs have a 1.5x factor, which changes the effective focal length of a 50mm lens to 75mm. An Olympus SLR's 2x factor would change a 50mm lens to 100mm.
Shutter speed range
Shutter speed rangeShutter speed controls the length of time that the camera lets in light to expose the camera's sensor. This specification shows the range of selectable shutter speeds by defining the minimum and maximum shutter speeds.

HeightThe height of the camera body is measured in inches and rounded to the nearest tenth of an inch.
WidthThe width of the camera body is measured in inches and rounded to the nearest tenth of an inch.
DepthThe depth of the camera body is measured in inches and rounded to the nearest tenth of an inch.
Total weightFor cameras with interchangeable lenses, it is the total weight of the camera body plus the lens it was tested with. The battery and memory card are also included in the total weight for all cameras.
Memory card slots/type
Memory card slots/typeThe number of slots and the type of memory card format the SLR uses for storing images.
Max. buffer size JPEG/RAW
Max. buffer size JPEG/RAWThis number essentially calculates the number of images (either JPEG or RAW files) that can be stored in a buffer (where files are stored temporarily) before the camera slows down.
LCD pixel count
LCD pixel countTotal number of pixels of the LCD monitor. In general, the higher the number of pixels, the clearer and sharper the image will be.
Still image formats
Still image formatsThe type of image file (or image file combinations) the camera uses to record and store digital images. Examples include JPEG and RAW file formats.
