Canon camera main parts

(1) UV lens:

Filter the excess ultraviolet rays in the air and protect the lens. UV brands, such as; Baogu, Kengo, Hasen, B W, and some original lenses of big brands, etc. Prices are also uneven: for example, from tens of yuan to hundreds of yuan. When you choose, you should pay attention to the coating on the surface of the UV mirror, especially when shaking under strong light, and seeing colorful colors, the light transmission performance is very good. Putting the camera in front of our eyes is a feeling that we can't see the camera. Moreover, lenses with tens of dollars are not strictly ultraviolet lenses (called protective lenses). First of all, the lens is not coated (there is no coating, and there is no function above the UV lens, just to protect the lens and prevent the lens from falling off). Putting them on the lens is like adding a piece of high-grade glass. The imaging effect is not as good as without lens.

(2) Liquid crystal protective film:

Mainly plays a role in preventing the LCD screen from being scratched. This protective film is used by electrostatic adsorption on the surface of LCD screen. If the surface of the protective film is seriously scratched after long-term use, it can be replaced in time, and it has no corrosive effect on the surface of the LCD screen. (The film used on the mobile phone sticks to the surface of the LCD screen and cannot be replaced. )

(3) Blowing:

Clean the dust on the lens and camera surface, but be sure to pay attention to it when cleaning. The blow head must be at a distance from the lens, and blow hard through the palm of your hand (this can ensure that the blow head will not accidentally touch the lens, causing scratches on the lens.

(4) lens cloth:

It should be used in conjunction with blowing. When wiping the lens, don't blow the floating ash on the lens with your mouth, so as to avoid saliva on the lens (especially after eating greasy things, once the lens is stained with greasy saliva, it is not easy to wipe it.

(5) Photographic bag:

First of all, the choice of camera bags should be selective (that is, what is the use of buying bags), such as rain, shock, dust and fire prevention. There are many kinds of camera bags on the market now: Jeep, Le Shebao, Weifeng, Buckingham, Nikko, Buster, Jiduoxi and so on.

Canon camera classification

(1) EOS series: professional positioning camera. EOS series are all digital SLR cameras, which can change lenses and adopt CMOS imaging, with good imaging quality and strong expansibility.

(2)Powershot series: positioning semi-professional cameras. Stylish appearance with manual function. CCD imaging. Suitable for photographers. The imaging is good and has certain expansibility. According to the needs of different users, Powershot series is divided into four series: A, S, G and P (1). A series is mainly for home users, and most of them are entry-level products. ⑵S series and G series are mainly aimed at middle and high-end users, and their performance and pixel indicators are higher than those of A series.
