How to save a SLR camera when not using it for a long time?

How to store a SLR camera if it is not used for a long time:

1. Put it in a drying box, remove the battery and lens, and cover it. If you don’t have a drying box, buy some moisture-proof silica gel and put it in your bag, and let the bag dry in the sun in advance.

2. When the lens is removed, it will be the same up and down, as long as it is not pressed down. It is best if the lens is placed vertically or flatly.

SLR digital camera refers to a single-lens reflex digital camera, that is, Digital, Single, Lens lens, and Reflex reflective in English Abbreviation DSLR.

SLR refers to single lens reflex, or SLR (Single Lens Reflex), which is the most popular viewfinder system today. Most 35mm cameras use this viewfinder. In this system, the unique design of the reflector and prism allows the photographer to directly observe the image through the lens from the viewfinder. Therefore, you can see exactly the same image that the film will "see".

SLR digital cameras have two main features. First, they can exchange lenses of different specifications. This is a natural advantage of SLR cameras and is incomparable with ordinary digital cameras. The second is to view the scene through the photographic lens. Most traditional camera lenses with the same mount will also work on DSLR cameras. Digital SLR cameras are more expensive than ordinary household digital cameras. SLR cameras are more suitable for professionals and photography enthusiasts. Most SLR camera bodies and lenses are sold separately.

The heart of the SLR system is a movable reflector, which is placed in front of the film plane at an angle of 45°. The light entering the lens is reflected upward by the reflector onto a piece of frosted glass. To correct for this defect, today's eye-level SLR cameras have a pentaprism mounted above the ground glass. This kind of prism reflects the light multiple times, changes the optical path, and sends the image to the eyepiece. At this time, the image is upright and corrected left and right.

When framing, most of the light entering the camera is reflected upward by the reflector to the pentaprism. The shutter of almost all SLR cameras is located directly in front of the film (because this shutter is located on the film plane, it is called Focal plane shutter), when framing, the shutter is closed and no light reaches the film. When the shutter button is pressed, the reflector quickly flips up to clear the light path, and the shutter opens at the same time, so that the light reaches the film and the shooting is completed. The mirror in most cameras then resets immediately.
