Introduction to photography, how to understand the lens name?

The lens name can be basically divided into four parts: lens category-focal length parameters-aperture parameters-special technology. Although many lens manufacturers have naming rules, they are basically in this mode. These logo characters are usually printed or etched on the pressure ring at the front end of the lens, and some are printed on the mirror body.

First, Nikon lens.

The naming of Nikon lens is a little more complicated, which can be roughly divided into the following parts: autofocus type, special function, designer (Nikkor Nikkor), focal length aperture, aperture control mode, ed use or not, internal focus or not, and the arrangement order is not necessarily.

Let's take AF-S Nikkor 70-200mm f/2.8G ED VR II as an example to illustrate:

1, AF-S This is an AF-S lens. AF-S refers to a single autofocus, and the camera pressed by the half shutter focuses once. Because the focus is locked, press the shutter to shoot. What is the full name of AF? Auto focus, that is, auto focus. S stands for silent wave motor, which means lens with ultrasonic motor. A * * * is divided into AF, AF-I and AF-S, and AF stands for this lens to support body-driven autofocus; AF-I stands for the built-in focus motor of this lens; AF-S, that is to say, this lens is an autofocus lens with a built-in noise reduction waveform motor, SilentWaveMotor.

2. Nicole said that Nicole, the manufacturer of Nikon lens, had nothing to say about it.

3, 70-200mm shows that this is a zoom lens, the focal length is in? Between 70 and 200 millimeters. If only 18 mm, 50 mm, 85 mm, etc. It means that this is a fixed-focus lens with constant focal length.

4.f/2.8 means that the aperture is constant, and the maximum aperture is F2.8. If the aperture is f/3.5-5.6, the maximum aperture is between f/3.5-5.6.

5.g indicates that this is a lens with aperture adjustment. The control mode of lens aperture is generally distinguished by D, G and E, which is usually marked behind the lens aperture value. Among them, the D lens is different from the other two, with an aperture ring design, while the G lens cancels the traditional aperture ring design, and the aperture is controlled and adjusted by the fuselage, because some early Nikon cameras do not support the aperture adjustment of the G lens; E-lens is a built-in electromagnetic aperture, which can be controlled by the electronic signal of the fuselage.

6、ED？ This is an ultra-low dispersion lens, which means that this lens contains? Ed. The lens can minimize the chromatic aberration of the lens, thus ensuring the excellent performance of the lens. In addition to this team, there is also IF: internal focusing internal focusing technology, micro:? Macro lens means that this lens is a macro lens with macro shooting function.

7. VR II This lens adopts the second generation anti-shake technology. Anti-shake technology can solve the photo blur caused by jitter when shooting below the safety shutter.

It should be noted that Nikon called its APS-C format DX and Quan Huafu FX. Where DX lens refers to APS-C special lens. Unlike the Kita brand, Nikon's DX lens can be installed on a full-frame camera. If there is no Quan Huafu lens, you can replace it with DX lens, but it will produce dark circles on the four sides of the photo, and the later cropping will not have much impact.

Second, other brands.

Canon lens names can be roughly divided into four parts: lens type-focal length-maximum aperture-lens characteristics. Sony also marks the lens classification after the aperture value, which is mainly divided into no logo, G logo and ZA logo. There is no logo, usually a cheap lens or a camera lens; The lens with G logo is Sony Minolta lens, and the lens with ZA logo is Sony's top lens. The naming method of Fuji Dragon lens is very similar to Canon lens. Lens type-focal length aperture-lens characteristics? Naming method, and the order is relatively fixed, so it is easier to identify,
