The lens has two fingers in film and television, one refers to the optical elements used by movie cameras and projectors to produce images, and the other refers to the continuous picture taken from power on to power off, or the fragment between two editing points, also called the lens. One finger and two fingers are two completely different concepts. In order to distinguish, one refers to the optical lens and the other refers to the lens picture.

How to remove the lens of the camera?

Cameras can be divided into interchangeable lens cameras and non-interchangeable lens cameras. The lens disassembly of interchangeable lens cameras is very simple, while the lens disassembly of non-interchangeable lens cameras is very troublesome.

A camera with interchangeable lenses is a camera with interchangeable lenses. This "disassembly" is not to disassemble the lens itself, but to disassemble the lens from the fuselage.

Specifically, the lens disassembly method of interchangeable lens camera (SLR camera or micro-single camera) is: press and hold the lens release button on the fuselage, and then unscrew the lens. As for the tightening direction, the interchangeable lens cameras of different manufacturers are different. Users only need to pay attention to the two marking points on the fuselage and the lens, and make them in an aligned state, so they can remove the lens accordingly. When installing the lens, they should also aim at two marking points before tightening the lens.

As for the lens disassembly of cameras with non-replaceable lenses, it is very troublesome. The lens of this camera itself has solidified into a whole when it leaves the factory and cannot be disassembled. If you want to dismantle it, you have to dismantle the camera as a whole. This is not a routine operation, only a few skilled people can do it. Unless the camera is disassembled, it is impossible for the average user to disassemble the lens of this camera.

How to disassemble the lens of SLR camera

Disassembly steps of Canon SLR camera lens:

3. Carefully remove the two metal rings you see.

4. Mark the focusing threaded sleeve and the lens assembly to mark the depth of thread precession; Then screw the lens assembly out of the sleeve, and then make a mark to mark the relative position of the two when screwing out; Finally, unscrew the ring piece in front of the lens (rotate counterclockwise with rubber ring or fingertip friction).

5. Remove the screws on the lens assembly, carefully open the lens assembly, and then remove the front lens group. At this time, you can see the diaphragm blade.

6. After removing the screw of the aperture assembly, remove the aperture blade, thus removing the lens.

Precautions for lens removal of Canon SLR camera

3. After the lens is disassembled, the fuselage and lens are separated and have been handled. Clean the body and lens housing with a clean rag.

4. If you don't use the Canon SLR camera for a long time, remove the lithium battery inside and put on the cover. Then put away all the parts, so that you can have a better shooting effect next time.
