The standard lens is suitable for shooting portraits, street shooting and other subjects. Usually, a lens with a focal length of 50mm is regarded as a standard lens with natural viewing angle and excellent image quality. The telephoto lens is suitable for shooting distant wildlife, sports competitions and other subjects. For example, a lens with a focal length of 70-200mm is a commonly used telephoto lens.

The price of lenses varies. If your budget is limited, you don't have to blindly pursue the most expensive lens. When choosing a lens, you can choose the right lens according to your own budget and needs.

Maintenance method of camera lens

When cleaning the camera body, first blow off the dust and hard particles on the surface with air, and then wipe the whole body surface with wet wipes. For parts that are difficult to clean, such as gaps and bayonets, you can use cotton swabs dipped in detergent to clean them at fixed points.

When cleaning the lens, first blow off the floating dust and hard particles on the lens with air, and then use the lens cloth with lens cleaner for deep cleaning. Wrap the cleaning cloth with lens agent on your finger, keep the same direction from the center of the lens, and wipe it outward with spiral force at a constant speed. For the lens of the rear lens group that goes deep into the bayonet, the microfiber lens cloth can be wrapped on a cotton swab for cleaning.

When cleaning the photosensitive element, it should be carried out in a dust-free environment and be very careful. First of all, it is necessary to detect whether the photosensitive element has dust or stains. Detection can be carried out according to the following methods: set the camera to full aperture, with the highest ISO value, manually focus to infinity, take pictures on a pure white background, and zoom in to see if there are black spots. If so, the photosensitive element needs to be cleaned.
