卓越的影像捕捉及銳利的演繹能力
基本功能再進階,例如51點對焦系統,全在一台輕量的機身中


The D7100 is a compact, lightweight camera (W x H x D: approx. 135.5 x 106.5 x 76 mm; weight: approx. 675 g*1) that offers superior portability. It is loaded with features that enable excellent subject acquisition and
rendering performance capable of reproducing the finest details.

D7100是一台完整、輕量,且提供良好攜帶性的相機
(W x H x D: approx. 135.5 x 106.5 x 76 mm; weight: approx. 675 g 註1)
他也有絕佳的影像捕捉、演繹能力來重現最佳的影像細節。


The high density of 51-point AF system accurately acquires the intended subject for superior subject acquisition and tracking performance. Cross-type sensors have been adopted for the 15 most frequently used focus
points at the center of the frame. In addition, the center focus point (cross-type) is fully functional with lenses with a maximum aperture of f/8. This means faster, more precise autofocusing with a variety of conditions. The D7100 is also equipped with a new crop image area, 1.3x DX crop, which increases the angle of view by approximately 1.3x that of the standard DX-format angle of view. This effectively increases lens focal length to an
equivalent angle of view of approximately 2x*2, making distant subjects larger. In addition, the 51 focus points cover the entire image area when 1.3x DX crop is enabled for quick and certain acquisition of subjects moving randomly through the frame with high-speed continuous shooting at approximately 7 fps*3.

高密度的51點對焦系統提供了準確的捕捉及追蹤物體的能力。
在中央最常用的15點對焦點為十字對焦點。
且相容於最大光圈f/8的鏡頭。這代表在多種情況下更快、更準確的自動對焦。
D7100也搭載了新的影像裁切區域,1.3x DX裁切。
這大約增加了比
標準DX格式感光元件1.3x的視角。
增加了焦長對等效視角約為2x *註2,讓遠處物體更大。
此外,當DX1.3裁切開啟時,所有51點對焦點是包含整個影像區域,且搭配高速連續7fps連拍,
以便可以快速地捕捉隨機移動的物體。

The D7100 is also equipped with a DX-format CMOS sensor, an effective pixel count of 24.1-million pixels, the high-performance EXPEED 3 image-processing engine, and does not have an optical low-pass filter. These
features enable excellent rendering with high resolution. The incredible potential of the high pixel count, high-definition D7100 can be maximized by the use of NIKKOR lenses, which offer superior rendering performance made possible with Nikon's own optical technologies.
The D7100 also offers a number of new functions that improve operation and support more natural and
efficient shooting, including Spot White Balance, a white balance Preset Manual option that allows users to
choose a specific subject from which white balance is measured with shooting in live view. Additionally, the D7100 features an RGBW array that enables more effective accumulation of light, as well as a large, 3.2-inch
high-resolution TFT LCD monitor with wide viewing angle, and an button that enables direct access to
frequently used functions.

D7100也搭載了DX格式的2410萬的CMOS,高效能EXPEED 3影像處理器,並且沒有光學低通濾鏡,
這些功能提供了高畫素下的絕佳影像演繹,高畫素的潛力可以在使用NIKKOR鏡頭下被最大的發揮出來。
D7100也提供了許多新功能來改善操作及提高拍攝效率,
包括點白平橫。在LV下,使用者有白平衡手動預設選項,來讓使用者選擇一個白平衡已被測量的特定物體。
D7100也有RGBW陣列達到更多等效的近光量。
也搭載了3.2吋高解析TFT LCD廣視角螢幕,
並且有按鈕可以直接存取常用的功能。

D7100 primary features

  1. 1.Support for lenses with a maximum aperture of f/8 and an AF system comprised of the high-density 51 focus
    points offering faster AF initiation

    The 51 focus-point AF system built into the D7100 utilizes the new Advanced Multi-CAM 3500DX autofocus
    sensor module with 51 focus points covering a broad range of the frame for more certain acquisition of the
    intended subject. Cross-type sensors have been adopted for more certain acquisition and tracking of rapidly moving subjects. In addition, the camera is able to focus automatically with extreme accuracy, even in lighting measuring just −2 EV (ISO 100, 20°C), roughly equivalent to moonlight. What's more, the center focus point
    (cross-type) supports autofocusing with lenses with a maximum aperture of f/8. This allows users to enjoy ultra high-speed AF shooting with a compact and lightweight system when a telephoto NIKKOR lens with a
    maximum aperture of f/4 and a teleconverter (2x) are used.

    D7100主要規格:
    支援最大光圈f/8鏡頭自動對焦,高密度51點自動對焦,提供更快AF啟動速度。
    D7100的51點自動對焦是新的進階Multi-CAM 3500DX對焦模組,涵蓋了廣大的區域,更能穩定地捕捉物體移動的傾向。十字對焦感應器也可能掌握即追蹤隨機移動的物體。
    此外,也可以在−2 EV (ISO 100, 20°C,約為月光下) 下有極佳的自動對焦準確度
    更甚的是,中央對焦點(十字)支援最大光圈f/8鏡頭自動對焦,這讓使用最大光圈f/4的望遠鏡頭搭配2倍加倍鏡後,
    也可以享受高速的自動對焦。

  2. 2. 51 focus points covering the entire frame bring distant subjects closer. 1.3x DX crop for high-speed
    continuous shooting at approximately 7 fps*1.

    The DX format effectively increases the shooting angle of view to an equivalent of approximately 1.5x the
    actual focal length of the lens*2. The new 1.3x DX crop image area increases this effect by an additional 1.3x
    for a total effective increase in angle of view to approximately 2x lens focal length*2, making distant subjects
    appear closer. What's more, when 1.3x DX crop is enabled, the AF system's 51 focus points cover the entire
    frame, and high-speed continuous shooting at approximately 7 fps*1 is possible for quick and certain capture of the intended subject.

    DX格式下視角比鏡頭的實際焦長等效增加約1.5x,新的1.3DX裁切區域在原本的效果上又增加了1.3X,所以總等效視角約為2x於鏡頭的焦長。讓遠端物體看起來更近,
    更多的是,當1.3DX裁切開啟時,51點自動對焦將佈滿整個區域,且高速連拍速度提升到約7fps。

  3. 3.A new Nikon DX-format CMOS sensor, an effective pixel count of 24.1-million pixels, no optical low-pass filter, and the EXPEED 3 image-processing engine optimized for high-performance digital-SLR cameras

    The D7100 is equipped with a new Nikon DX-format CMOS sensor, an effective pixel count of 24.1-million pixels and no optical low-pass filter. It supports a broad range of standard ISO sensitivities, from ISO 100 to ISO
    6400, as well as further expansion to an equivalent of ISO 25600 (Hi 2) for capture of sharp, clear images for which noise is effectively suppressed throughout the entire range of sensitivities. In addition, when used with NIKKOR lenses loaded with Nikon's advanced optical technologies, the D7100's high pixel count achieves
    sharp, well-defined rendering with a sense of depth. The EXPEED 3 high-performance image-processing
    engine maximizes the potential of the high pixel count for faithful reproduction of scenes.

    D7100配備了全新Nikon DX-格式 2410萬畫素CMOS,且無光學低通濾鏡。
    支援了更廣範圍的ISO感應度,從ISO 100-6400,可擴充到25600。
    在搭配有高階光學技術的NIKKOR鏡頭時,則更可以解放D7100的高畫素。
    EXPEED 3高效影像引擎則最大化了高畫素影像感測器的潛力,並忠實重現景物。

  4. 4.A compact and lightweight Nikon DX-format camera that is strong despite its light weight, and extremely
    portable

    Despite its advanced basic performance and being loaded with a number of new functions, the D7100 is a
    compact, lightweight camera measuring approximately 135.5 mm wide, 106.5 mm high and 76 mm deep, and weighing just 675 g*. As an entire system, the Nikon DX format, which includes DX-format lenses, offers
    excellent portability. The magnesium alloy adopted for the top and rear covers of the D7100 ensures great
    strength, and sealing of individual components ensures a high level of water and dust resistance.
    These aspects make the D7100 the perfect camera for a broad range of uses, from casual capture of everyday scenes to full-scale photography.

    儘管搭載了許多進階及全新的功能,D7100是一台完整且輕量的相機,長高深35.5 x 106.5 x 76 mm;
    重量約675g。Nikon DX格式,包含DX鏡頭,都提供了絕佳的攜帶性。
    機頂與機背使用了鋁鎂合金,提供了良好的強度;且有高度的防滴防塵能力。
    這些面向讓D7100在廣泛的使用範圍中皆是完美的相機。
