Identification of common parameters in Nikon SLR photography

What are the common logos of Nikon cameras and lenses? To learn Nikon SLR photography, you must master the common logos of Nikon SLR cameras and lenses. I sorted out the common logos of Nikon SLR cameras and lenses for you. Welcome to read the reference!

Nikon SLR lens commonly used logo

VR:

Nikon's lens anti-shake technology. Like Canon, Nikon's VR anti-shake has many modes. Normal is normal mode, which supports translation detection; Active is active mode, which is suitable for shooting when riding a vehicle; Sport refers to sports mode, which is suitable for shooting irregular moving objects, equivalent to Canon's IS 3 mode.

IF (internal focus) and RF (back focus):

The focusing lens group is located inside and behind the whole lens structure respectively. With the lens with internal focus or back focus, the length of the lens remains unchanged during focusing, and the front end of the lens does not rotate (it is convenient to use position sensitive filters such as CPL). However, IF lenses are everywhere? Reduce the focal length? The characteristics of? Only when the focal point is at infinity can the visual angle of nominal focal length be reached; When focusing at close range, the viewing angle will be larger (the focal length will be smaller).

CRC:

That is, floating focus. For lenses with floating focus design, the positions of more than 1 lens will change during focusing. Compared with the ordinary lens focusing only by 1 lens, floating focusing can make the lens have better imaging quality in the whole focusing range.

Nanocoating (n):

Nikon's nanocrystalline coating technology can effectively suppress ghost and glare. Usually there is gold on the mirror? n？ Words.

Anti-fouling fluorine coating:

Adding fluorine coating on the lens surface can improve the hydrophobicity, oil resistance and antifouling of the lens.

FL lens:

That is, artificial fluorite lenses have good low dispersion performance and can effectively correct chromatic aberration.

Enhanced/Super Enhanced Lens:

Nikon's low dispersion lens is also used to correct chromatic aberration.

PF (Fresnel phase) optical element;

It is equivalent to Canon's DO component, and effectively compensates the chromatic aberration by light diffraction. Compared with the optical system of general lens, PF lens can reduce the number of lenses and make them smaller and lighter.

Foreign exchange:

35mm Quan Huafu photosensitive element, about 36? 24mm (corresponding products are D5, D4 series, D3 series, D8x0, D7x0, D6x0 and Df).

DX:

APS-C format photosensitive element, the size is about 23.5? 15.6mm, and the equivalent coefficient is 1.5 (corresponding products are D2 series, D 1 series, Dx0, D500, D300 series, D 100, D7x00, D5x00, D3x00 and COOLPIX A).

XQD:

A new memory card, which uses the PCI Express transmission standard for data transmission, is regarded as the next generation CF card like the CFast 2.0 card. At present, it can provide a reading speed of up to 440MB/s, which can improve the continuous continuous shooting capability of the camera (corresponding to D5 XQD version and D4 series).

UHS-ⅱ:

UHS refers to ultra-high speed SD card. Among them, UHS-I provides the highest reading speed of 104MB/s, UHS-II provides the highest reading speed of 312mb/s, UHS-II adds a row of contacts on the basis of the original SD card, and it needs to cooperate with the camera and card reader supporting UHS-II to achieve the maximum speed (the corresponding product is Nikon D500).

Cost:

Nikon image processing technology and image processor, the latest is EXPEED5/5A.

3D matrix photometry:

Nikon's matrix photometry has two enhancement modes. Among them, 3D matrix photometry integrates distance information, but the lens needs a distance encoder (original D-type, G-type and E-type lenses) to turn on the 3D matrix photometry function.

Color matrix photometry;

Nikon's matrix photometry has two enhancement modes. Among them, the color matrix photometry uses RGB photometry module, which can identify the color of the subject. Starting 3D matrix photometry needs to be used with lenses with built-in CPU (AI-P manual lens, PC-E shift lens or automatic focus lens), while AI and AI-E lenses can start color matrix photometry by setting them as non-CPU lens data.

Highlight key measurement:

The camera is equipped with the maximum proportion of photometry for the bright part to avoid overexposure, and try to keep the details and levels of the bright part, which is suitable for shooting the environment with large light or complicated light, such as stage photography (corresponding products are D5, D8x0 series, D750 and D500).

Point measurement linkage:

Most models of Nikon digital SLR can provide point measurement linkage function, that is, in the mode of point measurement and manual focus selection, the position of focus is used as the basis for metering.

Photometric coupling rod:

Nikon F-mount lens has a history of more than 60 years. Although the physical structure of the bayonet is basically unchanged, some details will still affect the compatibility between the fuselage and the lens. For example, the non-AI early lens (before 1977) is installed on a Nikon SLR with a fuselage drive motor, which will damage the metering link of the fuselage. In order to provide compatibility for all F-mount lenses, Nikon Df has designed a retractable photometric coupling rod, and the lens type can be selected in the fuselage menu.

AF-F (servo focusing):

Continuous focusing can be performed in live view/video mode, which is equivalent to AF-C focusing mode in optical view.

3D focusing:

In AF-C continuous focusing, the starting point of focusing is manually selected, and the camera can identify the object according to its shape and color, and automatically adjust the focusing position. This 3D focusing function is similar to Canon's EOS iTR AF intelligent tracking recognition autofocus function, but the difference is that all models of Nikon SLR currently support this function, and Canon only supports a few products.

Group focus:

Group focusing uses five focus points (D5 9 and D500 9) at a time, and these focus points are in a peer-to-peer relationship, among which 1 point focuses. In contrast, the central point and peripheral points of the extended focus are in a master-slave relationship, and the peripheral focus only participates in focusing when the subject is not in the central focus group.

Electronic rangefinder:

A camera with an electronic rangefinder and a lens with an aperture above F5.6 can give the rotation direction of the focus ring when focusing manually (corresponding to most of Nikon's SLR).

Double screen magnification:

This is an auxiliary function of composition, which can confirm the perspective relationship with the subject in real-life mode, and is suitable for subjects such as architectural photography.

Quiet shutter release mode (q):

Nikon began to provide silent shutter release mode from D7000, but the Q mode of the early products delayed the rising time of the reflector (the reflector was raised when released), which was not a real silent shutter. The model with Qc mute continuous shooting mode in the later period is the real mute low vibration shutter release mode, which is similar to Canon's mute shutter function.

Optimized calibration:

Nikon's photo color style options include standard, bright, natural, portrait, flat and other presets, and can be customized and adjusted.

White balance:

Most cameras can only use the spot metering area in the center of the picture to measure color when customizing the white balance, while cameras that support the spot white balance function can measure any position in the picture in live view mode (the corresponding products are D7 100 and later high-end models).

AF and suffix:

Most of Nikon's original autofocus lenses are prefixed with AF. AF stands for autofocus, which is mainly driven by the motor of the fuselage and belongs to the early autofocus lens; AF-I refers to the lens type with built-in focus motor, and also belongs to transitional autofocus lens. AF-S is the most common product at present, and S stands for SWM ultrasonic motor, similar to Canon USM ultrasonic focusing motor. AF-P refers to the stepping focus motor used in a new generation of low-end lenses, which is equivalent to Canon STM focus motor.

Aperture suffix:

The aperture value of Nikon lens has many suffixes. ? d？ The suffix indicates a built-in distance encoder (with an aperture ring on the lens); ? g？ Suffix indicates that the lens has no aperture ring (there is still a distance encoder); ? e？ Suffix indicates that the technology of electromagnetic aperture control is adopted, which is equivalent to Canon's EF lens.
