7100 ovvero seconda generazione della serie 7mila, macchina reflex APS-C che da qualche tempo, per alcuni, ha iniziato ad affiancare* la D300s, cropped professionale che però sconta ormai l'avanzata tecnologica di sensori e sistemi di processing sempre più potenti.
E la 7100 sembrerebbe puntare a sostituire in toto la 300s ponendosi al vertice dell'offerta DX, a partire dalla realizzazione del corpo, tropicalizzato ed in lega di magnesio, e dalle specifiche dello shutter, garantito per 150.000 cicli.
Il sotto-sistema AF non è da meno poiché si tratta del nuovo Multi-CAM 3500DX a 51 punti, 15 cross-type, integrato con il sensore R,G,B da 2.016pixel 3D Color Matrix Metering II.
E' prevista anche una modalità di crop 1.3x (si, esatto, il crop su una cropped), utilizzabile sia in modo foto che video e che garantisce un burst di 7fps (15,4MPixel) e corrisponde ad un fattore di moltiplicazione di 2x, cioè, guarda il caso, equivalente a quello di un sensore m4/3...
Arriviamo quindi al sensore, un 24MPixel che con ogni probabilità non è di fabbricazione SONY (D3200) ma TOSHIBA (D5200): confrontando infatti le specifiche relative al numero effettivo di pixel ed alla risoluzione, esse sono identiche alla recentissima 5200 il che fa molto ben sperare sul fronte IQ.
In un recente articolo infatti abbiamo evidenziato come sia sul fronte video che su quello foto l'imager TOSHIBA APS-C da 24MPixel fosse superiore rispetto al suo alter-ego made by SONY.
Nikon inoltre commercializza la nuova D7100 dichiarando che essa è sprovvista di low-pass filter il che implica, similmente a quanto accade per la D800E, una risolvenza leggermente superiore: per i videomakers che stessero facendo un pensiero alla 7100 e che a questo punto pensassero immediatamente all'effetto aliasing, possiamo dire che Andrew Reid di EOSHD ha testato la 5200 trovandola totalmente priva di questo artefatto.
Il mirino è a pentaprisma con copertura del 100% e fattore di ingrandimento di 0,94x mentre il display posteriore, fondamentale per video e liveview, è un nuovo LCD da 3,2" e 1,2Mdots: unica pecca, dal nostro punto di vista, la posizione fissa.
Spot WB in liveview e video. La nuova funzione Spot WB consente di impostare il punto di bianco scegliendo un qualsiasi settore sullo schermo dal quale leggere i valori per regolare di conseguenza il bianco.
Controllo remoto fino a 120 metri di distanza. L'unità opzionale WR-1 è in grado di pilotare un esteso set di funzioni della fotocamera, sia foto che video ma il costo, circa 750 Euro, lo pone in un ambito in cui solo utenti specializzati ne potrebbero trarre beneficio.
Alcune unità per il controllo remoto di terze parti che sono in grado di sfruttare un buon 80% delle caratteristiche della macchina hanno infatti prezzi di gran lunga inferiori.

Melville, NY (February 20, 2013) - Nikon Inc. today announced the D7100, the HD-SLR that ushers in a new era of DX-format image quality and functionality for the experienced shooter and photo enthusiast. The lightweight Nikon D7100 has an impressive array of intuitive features and controls bolstered by rapid performance and a robust feature set that includes a new 24.1-megapixel CMOS sensor, Nikon's 51-point AF system and wireless connectivity.
"Solidifying Nikon's ongoing commitment to the DX-format D-SLR customer, the innovative D7100 provides new ways for photographers to capture their creative vision with incredible detail and precision, whether through still images or HD videos," said Bo Kajiwara, Vice President of Marketing, Planning and Customer Experience, Nikon Inc. "The D7100 blends the best creative features with advanced-level functionality to give the enthusiast exactly what they want and that's a great shooting experience before, during and after capture, from shooting to sharing."
Engineered for Exceptional Image Quality
At the core of the Nikon D7100 is a new 24.1-megapixel DX-format CMOS sensor, designed to render the truest, most detail-rich images possible and brilliant HD video. The innovative sensor design delivers the ultimate in image quality by defying convention; because of the high resolution and advanced technologies, the optical low pass filter (OLPF) is no longer used. Using NIKKOR lenses, the resulting images explode with more clarity and detail to take full advantage of the 24.1-megapixel resolution achieved with D7100's DX-format CMOS sensor.
Driven by Nikon's exclusive EXPEED 3 image processing engine, the D7100 realizes a focus on image quality that extends beyond staggering sharpness to outstanding images with a wide dynamic range in a variety of lighting conditions. A wide ISO range of 100-6400 (expandable to Hi-2 of 25,600) allows for more versatile shooting to capture challenging conditions such as nature at twilight or even sports under less-than-ideal lighting. Even at higher ISOs, noise is minimized for both still images as well as when recording HD video.
Performance and Features Geared for the Advanced User
The Nikon D7100 is designed for the experienced shooter ready to take their photography to the next level, who demands a camera that conveys reliability and performance, and who is eager to embrace the next photographic challenge. These features include:
- New 51-Point AF System- The D7100 features Nikon's professionally proven and lightning-fast 51-point AF system, with a new Multi-CAM 3500DX AF module. Additionally, the AF system and exposure are augmented with Nikon's 3D Color Matrix Metering II 2,016 pixel RGB sensor and Scene Recognition System, which recognizes the scene prior to shooting in order to adjust AF, AE, AWB and other parameters. The results of this system are accurate and even exposures, sharp details and vivid color, frame after frame. For additional precision, 15 of the 51 AF points are cross-type, and the center point is functional at f/8, giving DX photographers an additional telephoto advantage when using a teleconverter.
- Rapid Response and Operation - To help ensure the decisive shot is not missed, the D7100 can shoot at up to six frames per second (fps) at full resolution and up to seven fps when using the new 1.3x crop mode at slightly reduced resolution. Overall operation and image processing is swift, while startup and shutter lag is nearly imperceptible with a release time lag of 0.052s* (CIPA). Image data is also written to dual SD card slots, which accept the latest high-speed UHS-1 and SDXC cards.
- 1.3x Crop Mode - Sports photographers take note: Building upon the telephoto benefits of the DX-format, the D7100 has the unique ability to shoot in a 1.3x DX crop mode for both stills and HD video. While in this innovative mode, shooters will gain an extra telephoto boost (2X), and a boost in burst speed to seven fps, with 15.4- megapixel resolution. Additionally, while in this mode, the 51-point AF array covers more of the frame, allowing improved subject acquisition and tracking performance through the viewfinder.
- New High Resolution LCD - The new, wide and bright LCD screen is 3.2-inches and features a super high resolution of 1,229K dots. Now photographers can easily compose and check critical focus for HD video.
- New Viewfinder - Nikon has implemented a bright and high-contrast new OLED data display within the optical viewfinder that makes it easier to read and see shooting data. When composing through the viewfinder, users see 100% frame coverage, essential for proper framing.
- Spot White Balance - A new feature for Nikon cameras, Spot White Balance allows for quick and precise white balance adjustment while shooting in live view. By selecting a desired point on the screen, users can set a custom white balance from a distance, even while using a super-telephoto lens. This is helpful for shooting video or when shooting under unfamiliar lighting when no gray card is available.
- Durable Construction - Built to perform in a wide variety of conditions, the D7100 is built to the same moisture and dust resistance specifications of the venerable Nikon D300S. For durability, the top and rear covers are constructed of magnesium alloy, while internally, the shutter has been tested to withstand 150,000 cycles. Despite its robust construction, the camera remains lightweight, weighing in at approximately 1.5 pounds (body).
- Enhanced Interface - To make it easier for users to quickly access frequently used functions, the "i" button has been added to the enthusiast-oriented control layout on the camera.
Sharing and Remote Shooting Simplified
Photographers know that moment when the shutter clicks and they have created something stunning which deserves to be shared. No matter where that moment occurs, whether in an urban landscape or isolated forest, they can now share their images wirelessly by an attached WU-1a Wireless Mobile Adapter.1 With this optional adapter the user has the ability to share images to a supported smartphone or tablet, shoot remotely from their device, and transfer photos from up to 49 feet away. The Nikon Wireless Mobile Utility application is available free of charge on Google PlayTM for AndroidTM devices or from the App StoreTM. When using the application, photographers can wirelessly transfer images from the camera to a mobile device and even remotely control the camera.
Capture Exceptional HD Video
For those looking to create multimedia content, the Nikon D7100 has a wide variety of innovative features for capturing HD video at various frame rates. With a press of the dedicated video record button, video can be recorded at 1080/30p, or at 60i/50i (in 1.3x Crop Mode) for optimal playback on many HDTV's when connected via HDMI. The D7100 also provides the ability to record stereo sound through the internal microphone, or attach an optional external microphone such as Nikon's ME-1, through the dedicated microphone terminal. To reference audio, the camera also features a headphone terminal. Users can also get creative using Nikon's Creative Effects in real time. This feature lets users take advantage of modes like Selective Color or Color Sketch to create truly customized movies.
Full Control, Creatively
In addition to full manual controls, the Nikon D7100 features a variety of intelligent modes to create effects and special features so that users can unleash their creativity. Nikon's Picture Controls can be applied to photo and video to change the color, tone and saturation of an image for creative control. When capturing still images, the same Creative Effects modes and filters available in video are also at the disposal of the user. By combining consecutive frames, the D7100 also has a high dynamic range (HDR) function to let users capture photos with a vast tonal range.
NIKKOR, Speedlight and System Compatibility
For 80 years, the NIKKOR legacy has been providing world renowned optics for photographers. The D7100 is compatible with Nikon's dedicated DX-format lenses and more than 50 FX-format lenses. NIKKOR lenses offer the ultimate in sharpness and clarity in photos and HD video. For added versatility, the camera features a built-in flash, or can act as a commander in Nikon's popular Creative Lighting System (CLS).
WR-1 Transceiver
In addition to the D7100, Nikon also announced the WR-1 Transceiver for Nikon D-SLR cameras. This device uses 2.4 GHz radio frequency for maximum range when communicating with the camera, extending the range and functionality2 for remote shooting applications. The communication range between WR-1 units is approximately 394 feet3, and 15 channels are available. Users also have the ability to remotely control a camera (with a WR-1 used as a receiver) attached by operation of another WR-1 (used as a transmitter), and also perform simultaneous or synchronized release of shutters on several cameras using the WR-14. Furthermore, there are a wide variety of options for remote shooting, which include dividing remote cameras into groups and controlling each group separately and interval timer photography. Remote shooting by combining the WR-1 with WR-R10/WRT10 wireless remotes is also possible5.
