Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of camera accessories and cameras, and more specifically to a camera viewfinder protective mirror, a viewfinder protective cover and a camera. Background Art
[0002] A camera is a device used to capture and record images. It focuses light onto a photosensitive element through an optical lens, then converts the light into electrical signals, ultimately generating digital or film images. Cameras can take photos and record videos, and play an important role in recording, creating, and disseminating in the era of self-media, providing self-media practitioners with a wealth of tools and resources to help them better express their views and stories.
[0003] The viewfinder shield is installed on the front side of the camera's viewfinder. Some viewfinder shields are used to support the user's eye sockets when in use, keeping the eyes and the viewfinder at a suitable distance, and improving the user's comfort during the photo and video shooting process. This prior art viewfinder shield has the following defects: 1. When shooting on a rainy day, rainwater passes through the viewfinder shield and enters the camera through the gap of the camera viewfinder, causing the internal components to become damp and moldy. At the same time, it causes chemical corrosion to the coating layer on the lens in the viewfinder, affecting the later use. 2. When the camera is carried on the body, the viewfinder side will be attached to the side of the body. When walking back and forth, the forward and backward movement and left and right movement of the camera will contact and rub against the clothes. The static electricity generated will bring dust and cotton wool into the viewfinder. 3. When the camera is mounted externally, the buttons and zippers on the clothes will pass through the viewfinder shield and collide and rub against the transparency of the viewfinder, causing the viewfinder to be damaged. 4. When the user grabs the camera, the user's thumb will press on the viewfinder lens through the window of the viewfinder cover, leaving fingerprints on the lens. The user often needs to wipe the lens, which will be damaged over time, affecting the use effect and service life of the camera. Utility Model Content
